I’ve slept on a variety of memory foam mattresses so I know first hand how memory foam can contour to your body to relieve pressure at the touch points and offer a night of cozy and comfortable sleep.
Memory foam mattresses have become a hugely popular bed type and from testing experience I know just how much variety memory foam can have. Many of the recommendations in our best mattress buying guide are made using memory foam, so you have plenty of options available when choosing.
What makes a good memory foam mattress? The best memory foam mattresses offer cushioned comfort across the body, making them the preferred choice for helping people with aches and pains sleep more comfortably. My top pick right now is the Nectar Classic Memory Foam Mattress — we’re currently in the middle of retesting this model and it’s proving even better than we remembered.
The Black Friday mattress sales and deals are well underway, making now an excellent time to invest in the best memory foam mattress for your sleep health. My team has tested every bed in this guide, so read on to discover this year’s best memory foam mattresses…
1. The best memory foam mattress overall
Quick verdict: The Nectar Classic Memory Foam is a well-balanced, mid-range mattress that offers excellent pressure relief and support for your entire body. Although not a super sinking mattress, the surface does contour to your joints to provide the hug-like, cushioned comfort you expect from memory foam.
Yes, it's not the most luxurious mattress in this guide — the Saatva Contour5 at #3 wins that accolade. But it takes the top spot thanks to its great value for money: the Nectar mattress performed well in all our in-house tests, and is more affordable than many of its closest rivals. We found the Nectar Mattress comfortable for most sleep styles, and rate it among the best mattresses for side sleepers that we've tried. The temperature regulation also impressed us (although the Cocoon Chill at #5 is better for very hot sleepers), and while the edge support could be improved that's not unusual for an all-foam bed — and it outperforms many of the others here.
What we like about it...
✅ Good balance of softness and support: The cushioned build ensures the medium-firm Nectar still provides ample pressure relief. It's a good middle ground for those who want a bit of a foam 'hug' but hate feeling trapped.
✅ Excellent for couples: We expect a foam mattress to absorb motion well — the Nectar stands out for couples because it pairs this motion isolation with a feel that suits different sleep styles. Less compromise, more happy sleepers.
✅ Good cooling for an all-foam mattress: We awarded the Nectar 4 out of 5 for temperature regulation.. It can't compete with the Cocoon Chill (#5) but our testers avoided the sweaty nights that can plague all-foam mattresses.
What we don't like about it...
❌ Lacks support for back sleepers and heavy people: Our testers noticed that in some sleep positions (like on their backs) the Nectar had a tendency to sink at the hips. This can lead to lower back pain. The Puffy Cloud (#7) is better for dedicated back sleepers.
❌ Not a luxurious build: The Nectar Classic Mattress is our top memory foam choice because it provides a strong all-round performance at a good price — but it can't compare to the premium luxury of the Contour5 (#3) or the Tempur-Adapt (#6).
I've slept on both the original Nectar Classic and the new Nectar Classic Memory Foam Mattress, and I can really feel the difference. The new Nectar is a touch softer than the previous model, making it ideal for all sleeping positions now (before we rated it mostly for side and back sleepers). There's plenty of support here to keep your spine aligned in any sleeping position, and the contouring effect cushions your curves without making you feel like you're being sucked into the mattress. I think the Nectar Classic is fantastic value for money, and it's my top recommendation for anyone looking to buy a memory foam mattress online.

2. The best cheap memory foam mattress
Quick verdict: The Siena is a reliable, all-foam mattress by Resident Home, the same company behind the Nectar Classic at #1. We think it's the best cheap mattress you can buy. Only the Zinus Memory Foam at #9 is cheaper in this guide, but the Siena is better quality.
Budget memory foam mattresses often fall into the same traps: not enough support and a tendency to sleep hot. Our testers found the Siena Memory Foam Mattress side-stepped these issues, with a firm feel that holds the entire body and avoids the sinking 'hug' that can trap heat (although it's not as cool as the Cocoon Chill at #5). That firmness means you don't get the classic memory foam 'hug' of other mattresses (choose the Tempur-Adapt at #6 if that's particularly important to you). But it's also very sturdy — it doesn't suffer from the sag that often afflicts cheaper all-foam models.
What we like about it...
✅ Sturdy edge support: Memory foam mattresses have a reputation for being weak at the sides, but the Siena is an exception to that rule. It's particularly useful if you have mobility issues and need to push out of bed.
✅ Comfortable for stomach sleepers: The best mattresses for stomach sleepers are typically hybrids, but the Siena is the rare all-foam bed with enough firm support to keep your hips elevated when lying on your front.
✅ A durable build: Cheap memory foams can often show dips and sags, but our testers felt the Siena Mattress has good longevity and should be comfortable to use for several years.
What we don't like about it...
❌ No classic foam 'hug': If you're shopping for a memory foam mattress, there's a good chance you want the sink-in feel we associate with all-foam beds. You won't get that with the Siena, as this is a mattress you lie on top of. The Zinus at #9 is better for marshmallow softness, while the Nectar is a good midpoint.
❌ Lacks some pressure relief: The Siena mattress doesn't offer much cushioning at the touch points, and while it softens with use, the pressure relief could be improved. The Nectar Memory Foam mattress at #1 is a better option if you tend to wake up with sore shoulders.
I've been testing memory foam mattresses for years so I know how rare it is to find one that performs as highly as this one did for the small price tag. The Siena Memory Foam Mattress aced nearly all of my team's in-house tests, punching above its weight in terms of support, motion isolation, temperature regulation and edge support. The latter surprised me because most foam mattresses I've slept on have pretty weak edge support. I did find the Siena Memory Foam much firmer than advertised though, so don't pick this mattress if you like a medium feel – I'd recommend the Nectar Classic above instead. But if you love firm mattresses and enjoy the feel of memory foam, the Siena is your best bet.

3. The best luxury memory foam mattress
Quick verdict: The Saatva Contour5 is a premium memory foam mattress with a sumptuous finish akin to a five star hotel bed. Using dense high-quality foams to create a supportive hug feel, the Contour5 comes out on top for sheer quality — the only reason it isn't at number one is the hefty price tag.
With both a medium-firm and firm feel to choose from, the Contour5 can suit a range of sleep styles. Our testing panel found the thick foams comfortable from the very first night, with a cradling effect similar to the foams of the Tempur-Adapt (#6). Despite the pressure reliving hug, the Contour5 is able to maintain a cooler sleep feel. Perhaps not comparable to the Cocoon Chill (#5), but our lead tester never woke up sweating.
If you're looking for luxury, the Contour5 is untouchable. However, the high price tag can be an issue. The Saatva Loom & Leaf (Also tested) is a premium alternative, while the DreamCloud (#4) offers value for money luxury, but you'll miss out on the Contour5's exceptional pressure relief.
What we like about it...
✅ A cooler 'hug': Saatva uses cooling phase change material to keep temperatures low during the night. It's not quite the cool feel of the Cocoon Chill (#5), but the Contour5 keeps you in a close hug that's cozy, not stuffy.
✅ Multiple firmness levels: The Contour5 is available in a 'Medium' and 'Firm' feel, to suit more sleep positions. We tested the Medium and while slightly firmer than expected it's ideal for side sleeping. Front sleepers should consider the Firm.
✅ Sumptuous feel: Lie down on the Contour5 Mattress and it provides immediate comfortable cushioning — that's what our testers discovered, anyway. You can feel the quality in the foams as they contour to your joints.
What we don't like about it...
❌ Weak edge support: Weaker edges are common complaint of memory foam mattresses, but considering the price tag of the Loom & Leaf, we might expect better. Especially as hybrid Saatva mattresses often excel in this area.
❌ $99 return or exchange fee: The majority of the beds in this guide come with free returns, so the $99 fee from Saatva feels like a sore spot. It's not exactly a deal breaker — or that unusual, the Tempur-Adapt (#6) has a returns fee as well — but it is a frustration
It feels hard to justify the cost of the Saatva Contour5 at first, at full price, a queen is £2,995, especially as a queen Nectar Classic will often set you back just $649. But the Contour5 outshines most beds in this guide when it comes to design, durability and overall comfort. You can feel the quality in the dense foams, while the cooling technology ensures the Contour5 avoids the pitfalls of other all-foam beds. It can't beat the Nectar on price or benefits apart from shipping — Saatva offers free White Glove Delivery, compared to Nectar's standard free shipping — but if you have the budget I highly recommend the Contour5. If you sleep hot and have a small budget, I recommend the Cocoon Chill (#5) instead.

4. The best hybrid memory foam mattress
Quick verdict: The DreamCloud Mattress uses multiple layers of memory foam to add a plush touch to a hybrid build (hybrid mattresses feature springs alongside foams). Offering luxury at a lower price, it's significantly cheaper than the Contour5 (above), the cashmere blend cover provides pressure relief, while sturdy springs and a medium-firm feel make it a supportive pick for back and stomach sleepers.
The DreamCloud is a strong all-rounder, although our side sleeping testers found it took a few weeks to break in (the Nectar at #1 offers comfort quicker). The springs give the DreamCloud a bouncier feel than an all-foam bed but, unfortunately, not the improved edge support we might expect from a hybrid — it trails behind the Siena (#2). But this is still an excellent example of how memory foam can enhance a hybrid bed.
What we like about it...
✅ Well priced luxury: We often recommend the DreamCloud as a lower cost alternative to the Saatva Classic, our all-time favorite mattress. While the DreamCloud isn't quite as luxurious, it offers a competitive feel for much less.
✅ Supports back and stomach sleepers: Strong coils and dense foams work together to keep the lumbar region elevated. Our front sleeping tester was impressed with the lack of "hip dip", keeping their lower back pain free.
✅ Supportive for sleepers with bigger builds: The DreamCloud has a good weight capacity and a strong, supportive feel that meant our heavier tester could enjoy head-to-toe comfort.
What we don't like about it...
❌ No sink-in feel: The DreamCloud has some plushness, but this isn't a bed that 'hugs' the body. For a proper memory foam embrace, consider the Tempur-Pedic Tempur-Adapt (#6) or even the contouring of the Nectar (#1).
❌ Weaker edge support: Hybrid memory foam mattresses typically have stronger sides than all-foam alternatives, so the hit-and-miss edge support of the DreamCloud is disappointing. The Siena (#2) is all-foam but stronger at the sides.
❌ Needs breaking-in: It took some of our testers time to adjust to the DreamCloud, as it doesn't have the soft relief a side sleeper might expect. For a mattress that feels comfortable right away, consider the Puffy Cloud (#7).
Like the Nectar Classic (#1), the DreamCloud Hybrid Memory Foam was redesigned a few months ago. It's shorter at 12" (the older version was 14" tall) yet somehow packs in an extra layer. I highly rate DreamCloud mattresses and recommend the Hybrid Memory Foam to people who want a more responsive mattress (compared to all-foam beds) that still offers excellent pressure relief. The DreamCloud is the second highest-rated mattress my team has tested, and while you can buy it in a pure memory foam version, I think the Hybrid Memory Foam option is the most supportive. It keeps the spine aligned in all sleep positions, and gets rid of excess heat quickly for cooler sleep. My only gripe is that it takes a few weeks to break in, but once done it's seriously comfortable.

5. The best cheap cooling memory foam mattress
Quick verdict: The Cocoon by Sealy Chill mattress is an all-foam bed that uses a phase-change material cover to wick away heat and sweat. As a budget-friendly all-foam mattress, our testers were initially skeptical of the Cocoon's cooling abilities. But after a few weeks sleeping on it, we agreed this is one of the best cooling mattresses around.
The stand-out feature is the phase change cover, which absorbs heat for cooler nights. It can't quite compare to the premium cooling of the GhostBed Luxe in our Also Tested section, but on the other hand, the Cocoon is more than half the price. With a similar, if slightly firmer, feel to the Nectar at #1 the Cocoon Chill suits most sleep styles, but side sleepers might prefer the plusher Saatva Contour5 (#3). Hot sleepers on a budget — you can't beat the Cocoon by Sealy Chill.
What we like about it...
✅ A cooler feel on a budget: Cooling mattresses are typically premium beds, but the Cocoon by Sealy Chill offers high-quality temperature regulation at a mid-range price.
✅ Comfortable for most sleep positions: The Cocoon Chill has a medium-firm feel with good pressure relief that will suit most sleep styles. If you have a bigger build, you'll probably feel more comfortable lying on your front or back.
✅ Eases back pain: The Cocoon Chill holds the lumbar region in a comfortable neutral alignment and the cooling is another bonus — you're less likely to toss and turn (potentially aggravating an injury) if you're a comfortable temperature.
What we don't like about it...
❌ Limited contouring: The Cocoon Chill does gently adapt to your frame, but there isn't the classic 'hug' you might expect from memory foam. If you want a squishy embrace that doesn't sleep hot, consider the Contour5 at #3 (but be prepared to pay more).
❌ Too warm for seriously hot sleepers: If you struggle with night sweats or hot flashes, the Cocoon Chill might not provide the specialist cooling you need. Upgrading to the hybrid version will enhance cooling, otherwise, consider the GhostBed Luxe (Also Tested) for a softer feel with even better temperature regulation.
I'm a hot sleeper so I'm naturally wary of memory foam mattresses (I've tested far too many that transform into mini ovens within an hour of sleeping on them). The Cocoon by Sealy Chill Memory Foam is an outlier on two fronts: one being that it dissipates heat well, and this down to its use of gel memory foam and a cover infused with heat-wicking Phase Change Material. It's also an outlier because it does all that cooling (in addition to reducing painful pressure points along the body) for a fraction of the average cost of a queen size mattress ($699 plus $179 of free bedding). By the way, it's always 35% off – so don't feel rushed to buy it if you need more time to consider your purchase.

6. The best memory foam mattress for back pain
Quick verdict: If you want a classic memory foam feel, you'll find buckets of it with the Tempur-Pedic Tempur-Adapt mattress. Tempur Materials are the original memory foam, with a cushioning that immediately contours to your body. A sturdy supportive core makes the Tempur-Adapt good for front and back sleepers, and our sleeper with back pain felt relief as soon as their lumbar touched those squidgy Tempur-Pedic foams.
The Tempur-Adapt has a comparable feel and price tag to the luxurious Contour5 (#3), but without the options (or the cooling) of its rival. However, Tempur Material is known for its unique feel and for many, the slow-moving foam is worth the investment. While the Puffy Cloud (below) has fantastic back support for the price, it lacks the sumptuous feel of the Tempur-Adapt. The ZInus (#9) has a similar squishiness, but honestly, can't compare.
What we like about it...
✅ Pressure relief at the lumbar region: Tempur Material foams are known for their cushioned 'hug', and with the Tempur-Adapt you'll get this marshmallow softness across your lower back, reducing pressure for fewer aches and pains.
✅ Comfortable for back and stomach sleepers: It's not all about the cushioning with the Tempur-Adapt, as a layer of dense foam at the base of the mattress keeps your spine from sinking too far.
✅ Top quality motion isolation: We expect good motion isolation from a memory foam mattress, but the Tempur-Adapt goes above and beyond. Our testers found the Tempur-Adapt able to "absorb virtually every movement".
What we don't like about it...
❌ Sleeps very warm: Our lead tester sleeps warm and regularly woke up sweaty on the Tempur-Adapt Mattress. The Cocoon Chill (#5) and GhostBed Luxe (Also Tested) are specialist cooling foam beds, but even the cheaper Nectar (#1) stays cooler overnight.
❌ No options: Unlike the similarly priced Saatva Contour5 (#3), the Tempur-Adapt is available in just one firmness option. Unless you want to pay to upgrade, that is — the versatile ProAdapt is around $1,000 more for a queen.
❌ Lacks support for side sleepers: Our side-sleeping testers had mixed results with the Tempur-Adapt. Some felt it too firm at the shoulder, others too soft at the hip, and one found it took a while to get comfortable. The Tempur-Cloud and Leesa Original (Also tested) are better for side sleepers.
Tempur-Pedic mattresses are like Marmite: half of my team love the way they feel, half hate it. Personally, I rate Tempur-Pedic beds. I slept on a Tempur foam mattress during the third trimester of my pregnancy, when I was dealing with excruciating hip and lower back pain, and it was the only thing that helped me feel comfortable enough to actually sleep. That's also the level of comfy pressure relief you can expect from the Tempur-Pedic Tempur-Adapt. This is our best-rated memory foam mattress for back pain, with my lead tester getting instant relief the moment she laid on it. There is a downside though: it retains heat, so you'll need to consider an alternative (such as the Cocoon by Sealy above, which is also cheaper) if you have night sweats or hot flashes.

7. Best memory foam mattress for back sleepers
Quick verdict: The Puffy Cloud Mattress has a firmer feel, counterbalanced by a plush quilted surface. After a month of testing we rate it the best memory foam mattress for back sleepers because it delivers support to the entire lumbar region while cradling the touch points to prevent pressure build up.
Our testers fund there isn't much sink to the Puffy Cloud Mattress, allowing the spine to rest at a neutral angle when in a back sleeping position, for fewer aches and pains. Side sleepers should also get on with the Puffy Cloud, as the quilted top provides pressure relief at the shoulders and hip. However, particularly lightweight sleepers might prefer the softer Nectar (#1). Weak edge support is an issue, but overall we found the Puffy Cloud enjoyable to sleep on — if perhaps not as luxurious as the Saatva Contour5 (#3) or the DreamCloud (#4).
What we like about it...
✅ Medium-firm support: The Puffy has a firmer feel for a memory foam mattress, similar to the Siena (#2). Your back will feel supported from the neck down, without the twisting that can occur when you’re sucked into a softer mattress.
✅ Cushioned pressure relief: Layers of felted fiber and memory foam ensure comfort the second you lie on the Puffy Cloud, relieving pressure where the body pushes into the bed. It’s a cheaper alternative to the Tempur-Adapt (#6).
✅ Cool to the touch feel: The Puffy Cloud cover feels refreshingly cool and maintains a neutral feel during the night.
What we don't like about it...
❌ Strangely slippery cover: If you hate making the bed in the morning, watch out for the slippery effect of the Cloud cover. Our testers found the sheets often came loose, unlike the smooth cooling of the Cocoon Chill (#5). But the bigger issue with the silky surface relates to edge support...
❌ Lacks support at the edges: By itself, the edge support is average for an all-foam bed. Add on the slippery cover and things become a little more precarious. The cheaper Siena (#2) is superior here.
The Puffy Cloud delivers an excellent balance of comfort and support. The breathable cover feels plush (albeit a little slippery), while the comfortable pressure-relief foam promotes good spinal alignment. I recommend it for back sleepers who don't want a mattress they'll sink into, but also want to avoid a super firm feel. There's just enough cushioning at the pressure points to alleviate firmness and make this a good middle ground.

8. Best memory foam mattress for joint pain
Quick verdict: The Purple Original Mattress isn't your standard memory foam bed, but that's why it's our top pick for joint pain. Sitting alongside the layers of foam you'll find the Purple USP: a GelFlex Grid that uses hyper elastic polymer to mold to the joints and create an almost weightless pressure relief.
The GelFlex Grid gives the Purple Original a unique feel, one that it took our review panel some time to get used to — it's not the classic foam of something like the Nectar (#1). However, after an adjustment period, the GelFlex Grid comes into its own. It's soft where you need cushioning, firm where you need support, and quick to respond if you toss and turn; our testers described it as akin to "floating on air". There isn't the plush finish of other memory foams (like the Puffy Cloud above), but there's oodles of pressure relief for aching joints.
What we like about it...
✅ Responds to your movement: The geometric shaping allows the GelFlex Grid to cradle every joint, and unlike the slow reacting Tempur-Adapt foams (#6), it moves quickly to embrace any new sleep positions.
✅ "Floating" relief: Overall, the Purple Original has a medium firm feel, but that doesn't quite describe it; It's squishy in some places, gently firm in others, and responds to pressure to create that "floating" feeling your joints will appreciate.
✅ Good air circulation: Unlike dense foam, the grid provides open spaces for hot air to circulate and cool, similar to the breathable feel of a hybrid (like the DreamCloud at #4). Our testers found hardly any heat got trapped overnight.
What we don't like about it...
❌ Odd sleep experience: Expect to take some time getting used to the Purple Mattress, as the GelFlex Grid has an unusual feel. If you want a more traditional memory foam at a similar price, try the Leesa Original Mattress (Also tested).
❌ On the thin side: The Purple Original is just 9.25 inches tall, which is under the 10-inch recommended mattress thickness for adults. We still think adults will feel supported by the bed, but in comparison, the Nectar (#1) is 12 inches tall.
I recommend the Purple Mattress to sleepers with joint pain who don't mind a few initially uncomfortable nights in the pursuit of pain relief. Our testing panel needed some time to get used to the feel of the Purple's GelFlex Grid, but soon feel in love with the "floating" pressure relief. The responsive support suits a range of sleep styles, although the thinner build might not be ideal for lightweight side sleepers and those with a bigger build.

9. Best memory foam mattress on Amazon
Quick verdict: The Zinus Green Tea Memory Foam Mattress is an entry level all-foam mattress. The simple build helps keep the overall price low, but Zinus doesn't skimp when it comes to cushioned pressure relief. For side sleepers, the Zinus offers a dreamy all night 'hug'. It's similar to the Tempur-Adapt (#6) but without the luxurious support — however, it's also much, much cheaper.
Compared to the similarly priced Siena (#2), the Zinus has some of the pitfalls we expect from a cheap memory foam. The support is soft at the edges, while the foams trap heat in the night. And while the overall quality is decent, expect reduced durability. However, this is an Amazon best seller for a reason, and that reason is deep relief at a low price from a convenient marketplace. But if you have the money for more, consider upgrading to the Nectar (#1)
What we like about it...
✅ Plenty of cushioned pressure relief: You sink into the soft layers of the Zinus, as the foams contour to you to improve weight distribution and alleviate pressure. Like the Saatva Contour5 (#3), the relief is notable at the shoulder and hips.
✅ Absorbs most motion: The slow-moving Zinus foams capture movement to keep it trapped to one part of the mattress. Your partner could jump up and down on their side of the bed and you'd hardly feel it.
✅ A classic foam feel: The all-foam Zinus delivers the 'hug' that defines memory foam for many of us. It's a cuddle in a mattress, contouring to your shape to hold you comfortably overnight.
What we don't like about it...
❌ Too soft for back and stomach sleepers: There's a quicksand effect to the Zinus, which allows your lower back to sink deeper into the mattress. The Siena (#2) is similarly priced and offers much more support for those who lie on their front or back.
❌ Very weak edges: Our lead tester found they lacked stability when lying on the edge of the Zinus Memory Foam Mattress, and the sides sag when you press against them. Weak edges aren't unusual for an all-foam bed, but the Nectar (#1) does better.
❌ Lacks some durability: Customer reviews indicate the Zinus Memory Foam Mattress can show some signs of sagging after a few years of use. If you can afford to upgrade to the Nectar, expect improved longevity.
The Zinus Green Tea Memory Foam Mattress is an inexpensive bed that delivers good comfort for the price tag. I recommend it for side sleepers — if you're a front or back sleeper, the Siena is a better choice — and plenty of cushioning can help you avoid numb hips and shoulders. Just make sure you don't sleep too close to the edge, or you migt come crashing off the sides.

How we test memory foam mattresses
At Tom's Guide, we are consistently researching and testing new memory foam mattresses so we can recommend the best ones. Our review process is editorially independent, and our team of expert testers use a set criteria to ensure you get a well-rounded, unbiased opinion. Only the very best memory foam mattresses make it into this guide.
We test all memory foam mattresses in these key performance areas: support, comfort, pressure relief, motion isolation, temperature control, edge support, and build quality. Each mattress is tested by one lead tester, with a further testing panel consisting of people with different sleep styles and body types also trying the bed to provide a range of opinions.
After a testing period of at least three weeks, we compile our results into a review. We also analyze customer reviews to identify potential areas for concern or praise that are affecting the wider user base. You can learn more about our testing process on our mattress methodology page.
Memory foam mattress FAQs
How to choose the right memory foam mattress
Why you can trust Tom's Guide Our writers and editors spend hours analyzing and reviewing products, services, and apps to help find what's best for you. Find out more about how we test, analyze, and rate.
When choosing a memory foam mattress, my number one piece of advice is to opt for a mattress with a sleep trial. A sleep trial gives you a period of time to test the bed. If the mattress isn't right for you, you can return it within the trial period. It can take a while to adjust to a new mattress, particularly if you're switching from a hybrid to an all-foam model, and the trial gives you a chance to make that adjustment from the comfort of your own home.
After the sleep trial, I recommend prioritizing your sleep position when buying a memory foam mattress. Side sleepers need lots of cushioning, which is something memory foam generally does well. Back sleepers need more support, balanced by cushioning. Stomach sleepers, on the other hand, need to prioritize lumbar support — which can make it hard to find a good memory foam mattress.
Your body type is another key consideration. Memory foam mattresses can be suitable for bigger bodies, but it's important to choose one with a good weight capacity (most standard mattresses support up to 250lbs per person). And if you have a larger build, it's best to avoid all-foam mattresses with too much "sink".
It's also important to think about your sleep needs: do you share a bed? Are you a hot sleeper? Do you need help getting off the mattress in the morning?
Bed sharers can often benefit from memory foam mattresses, as these models are known for their motion isolation. The dense foams are capable of capturing movement and absorbing it, so your partner can toss and turn without bothering the other person in the bed.
However, the thick foams also have a reputation for holding onto heat, meaning they aren't always the best choice for hot sleepers. If you sleep hot but you want a memory foam bed, I recommend looking for models with specialist cooling properties, such as gel-infused foams, phase change materials and perforated foams.
Memory foams can also lack edge support; when you sit or push against the sides, they show significant sink. This can be an issue if you have limited mobility and need to press against the mattress to get up in the morning. Firmer memory foam mattresses tend to have stronger sides than softer models.
How long does a memory foam mattress last?
A memory foam mattress can last for up to 10 years, which is when we recommend replacing your mattress. The average lifespan is around six to 10 years. After this, you might notice your mattress starts sagging, and the foams retain the dips where you've been lying on the bed.
You can extend the life of your memory foam mattress by caring it for it properly. We have advice on how to clean a mattress, while some brands recommend rotating your foam bed to delay sagging. A mattress protector is also essential, to prevent stains and damp from damaging the foams.
A mattress warranty can help you better understand the potential lifespan of your mattress. 10 years is considered a standard warranty, but some brands, such as Nectar and Saatva, offer a lifetime warranty. This indicates they have a lot of faith in the integrity of their materials.
What is the best depth for a memory foam mattress?
We recommend a mattress thickness of at least 10 inches for an adult. A mattress this tall should be able to accommodate the layers needed for both comfort and support, with enough height to prevent the uncomfortable feeling that you might sink through the foam and out the other side of the bed.
Thicker, plusher mattresses are often recommended for side sleepers, as they have ample cushioning where the body presses against the bed. But that doesn't mean you can't get comfortable on a shorter mattress: the Leesa Original is great for side sleepers and just 10 inches tall.
Shorter mattresses can have enough support for adults, but they need high quality materials to achieve this (the Purple Original is a good example). Budget mattresses under 10 inches tall are often better for guest rooms or children.
What density of memory foam is best?
Foam density is an often overlooked attribute of a good memory foam mattress. As a general rule, high-density foams are more comfortable and have better durability than low-density foams. A good memory foam density is around 2.5lb, with 1.5lb being the acceptable minimum. Some luxury mattresses feature even denser foam (3lb and above), but you'll have to pay more for this increased density — the Saatva Contour5 has an ultra-premium 5lb memory foam core..
High-density foams offer durable cushioning, while low-density foams are more likely to start sagging after just a few years of use. However, foam density doesn't change the firmness of the mattress: a 3lb foam can be soft or firm.
Unfortunately, finding foam density figures can be tricky. If you're curious about the density, try checking the specs or contacting the brand directly. While we don't factor the exact density into our reviews, we do consider the overall durability of the mattress before making our recommendations.
Memory foam vs hybrid mattress: Key differences
Memory foam mattresses consist of multiple foam layers, with memory foam often used in the upper layers for comfort and stable foams layered beneath for support.
Like memory foam mattresses, hybrids also use comfort layers and support layers. However, while many hybrid mattresses use memory foam as cushioned comfort layers, these typically sit on top of a layer (or layers) of springs.
Beyond the build, memory foam and hybrid mattresses often have key differences in feel. Memory foam mattresses are known for their 'sink-in' feel, with the adaptable foams providing pressure relief and motion isolation. However, they do have a reputation for weaker edge support and a tendency to sleep hot.
The use of springs typically gives hybrid beds stronger edges and better temperature control. They're also bouncier, without the 'hug' of foam. This can make it easier to move around and change position, but sometimes result in disruptive motion transfer.
In this guide, alongside all-foam mattresses we've also included memory foam hybrids, such as the DreamCloud. These mattresses pair springs with memory foam layers for a bed that balances cushioning with bounce.
Other hybrid mattresses, including some of the choices in our best hybrid mattress guide, use different materials as comfort layers. This includes latex foam and wool.
