Mattresses remain at their lowest prices in the Cyber Monday sales this morning – I’m a certified sleep expert and I’m bringing you the best deals of the day, live

The number one deal I recommend

If you're looking for luxury, then I have some good news: one of the best luxury mattresses is reduced in one of the best mattress sales of Cyber Monday. Yes, I'm talking about the Saatva Classic. Rated our number one best mattress, you just have to glance at the practical galaxy of five stars we awarded in our Saatva Classic Mattress to see why we love it. We awarded full marks for motion isolation, temperature control, pressure relief, edge support, durability and the whole package. Senior Sleep Editor (and Certified Sleep Science Coach) Claire Davies described the Saatva Classic as the “comfiest, most supportive mattress [she’s] ever slept on”.

So the fact that you can save $400 on the Classic Mattress at Saatva today is, in my opinion, excellent value. I don’t expect the price to drop any further from here on out, so if you want to experience all-round sleep luxury, shop now.

What to look for in a decent luxury mattress this Cyber Monday

Nicola Appleton, Sleep Editor, Tom’s Guide

If you’re shopping for a luxury mattress in the Cyber Monday sales, you might be wondering how to spot a decent one from a dud. Firstly, our guide to the best luxury mattresses contains our 11 top options, so if it features in there, it comes with our seal of approval. But for a quick explainer on what makes a luxury mattress a worthwhile investment, here’s my quick tips.

1. Does it come with a decent warranty?
You might have noticed that some mattress brands, like Saatva, DreamCloud and Nectar, offer lifetime warranties. This doesn’t mean that your mattress will last forever, but it does speak volumes about the quality of the mattress you’re buying. A long mattress warranty = a brand that has faith in the construction of their bed.

2. Does it contain quality materials?
A truly luxurious mattress will be crafted from top-quality materials, whether that’s Tempur-Indulge memory foam in the Stearns & Foster Lux Estate, the cashmere blend cover in the DreamCloud mattress, or the GOTS certified organic New Zealand wool in the Saatva Classic.

3. Is it comfortable?
What’s comfortable for one person might not be comfortable for the next. So think carefully about what position you sleep in and what your sleep needs are before making your purchase. For more help, we’ve written a guide on how to choose a mattress.

4. Is it worth its price tag?
It’s a common trap to fall into, but a high MSRP alone doesn’t make a mattress luxurious. Instead, take all of the pointers above into account. Does it come with a lengthy warranty? Does it contain quality materials? Does it actually suit your sleep style? If the answer is no, then it’s not worth the investment.

Now you know the difference between a memory foam and a hybrid mattress (if you don't, scroll down for a quick explainer) let's explore two of the best deals on our favorite memory foam and hybrid mattresses: the Nectar Memory Foam Mattress and the DreamCloud Hybrid Mattress:

Memory foam vs hybrid mattress: which should you buy?

Earlier, our Features Editor Lauren explained why she's glad she swapped her hybrid mattress for a memory foam (and why she thinks you should too). But if you're new to mattress shopping, you might be wondering just what on Earth we're talking about. So let's break down the difference between memory foam vs hybrid mattresses....

• Memory foam beds excel at pressure relief and motion isolation
• Hybrids are generally more supportive, bouncier, and cooler
• Hybrids are typically pricier than memory foam mattresses

The obvious difference between memory foam and hybrid mattresses is their construction. Memory foam mattresses are made exclusively of foam, whilst hybrids use foam and springs. Hybrids are typically pricier than all-foam mattresses as the former includes more materials.

Memory foam mattresses are known for their excellent motion isolation, as the dense foams can trap movement (and there's no bouncing springs). Thick foams also help distribute body weight around the pressure points, which is good news for anyone with joint pain. However, some people may find it difficult to move around and feel 'stuck.' Not everyone likes feeling hugged by their mattress.

Most hybrid mattresses will make you feel as if you're floating atop the surface – there's less 'sink' than an all-foam. The reactive flex of the springs provides a stronger foundation, as well as better airflow and edge support. On the other hand, hybrids may not limit movement as well as foam mattresses.

Consider swapping your mattress to memory foam this Cyber Monday

Lauren Jeffries, Sleep Features Editor, Tom’s Guide

I was always very skeptical about memory foam mattresses, hating that hugging, sinking in sensation. I assumed they’d make me feel claustrophobic, so I opted for cheaper spring mattresses instead. However, when the opportunity came my way to try the Nectar Luxe Memory Foam Mattress, I decided to give it a try.

I’m so glad I did. Since swapping to memory foam, I don’t ‘sink in’ like I thought I would, but I lie on top of the mattress, with key pressure points like my shoulders, hips and knees sinking slightly. Just enough to relieve the pressure but not enough to feel like I’m being smothered. The motion isolation is superb, too, and it’s really helped my partner and I sleep through the night without disturbing each other. For more information about my experience, read our Nectar Luxe mattress review.

So, I’d strongly suggest shopping the best memory foam mattresses this Cyber Monday, with the Nectar Luxe memory foam mattress being the comfiest bed I’ve ever slept on.

Pros and cons of buying a mattress or bed topper from Amazon

Frances Daniels, Sleep Staff Writer, Tom's Guide

Sometimes you just need to buy a new mattress. But, often, a mattress topper is a cheaper way to get a few more years out of your mattress, before you replace it... So if you're thinking about buying a mattress topper at Amazon in the Cyber Monday sales today, I've got some advice for you.

After all, Amazon is a good option for budget beds, cheap mattress topper deals, and lightning-fast shipping. You’ll find some of our top picks for best cheap mattress and the best cheap mattress toppers all over the site. But what are the benefits and pitfalls of buying a bed or mattress topper from Amazon?

Here are the things I’d like you to know before buying a mattress or topper from Amazon...

3 pros of buying from Amazon

✅Cheap deals:
You can often pay much less for a mattress on Amazon than if you were to buy it directly from the brand, even if it’s only on certain sizes.

✅Faster shipping
The Cyber Monday sales can cause an increase in demand, leading to shipping delays and back orders. Amazon, on the other hand, is known for their speedy delivery — a huge plus if you need a bed before Christmas.

✅More options
Brands run out of stock or discontinue certain models when revamping their collections. Amazon gives you the chance to buy discontinued models and items that are sold out on the brand’s website.

2 cons of buying from Amazon

❌No sleep trials or warranties
The beauty of buying directly from a brand is that their benefits are clearly outlined, such as a sleep trial. While Amazon usually offers 90-100 day returns, they don’t offer official trials which allow you to literally sleep on your purchase for an allotted number of weeks.

❌Less reputable:
While you can find mattresses and bed topper from reputable brands at Amazon, there are a lot of cheaper beds from less well-known brands that you may be tempted by, but aren’t always the best quality. Plus, be aware of fake reviews and how to spot them.

Three reasons to replace your mattress - instead of a getting topper

Frances Daniels, Sleep Staff Writer, Tom's Guide

Cards on the table: I love a good mattress topper. They're cost-effective, add extra comfort or support, and can prolong the life of your exisiting mattress. All in all, they save you from buying a new mattress — or, at least, they save you from buying a new mattress for the next few years.

However, sometimes you have to admit that you can't literally cover up your bed's issues with a mattress topper. Here are three reasons to replace your mattress instead of buying a new topper:

1. Your mattress is over 10 years old
All mattresses need to be replaced at some point, and by that we mean at least every decade. So, unless you have an organic latex bed (which can last up to 25 years), it's likely that your mattress is past its expiration date and should be replaced ASAP.

2. Your mattress isn't supportive enough
All mattresses start to sag over time, leading to an uneven and unsupportive sleep surface. No topper will fix a dip that is more than two inches deep

3. Your mattress is damaged
If your mattress is ripped or badly stained, this could lead to deterioration of materials. In some cases, stained and unclean mattresses lead to mold or mildew and can even trigger allergies.

The mattress I’d buy this Cyber Monday

Rachael Penn, sleep and mattress writer, Tom’s Guide

I’ve written about scores of mattresses throughout this holiday sales event, but there’s one deal that stands out for me this Cyber Monday — the Casper Snow. So what makes it special?

It’s all about the cooling tech. If you’re anything like me and overheat at night regardless of the season, then you’ll be drawn in by the Snow’s innovative cooling layers, which include a cool-to-the-touch cover, phase change materials, and heat delete bands, which work to wick away heat while you sleep. It’s a medium-firm mattress, which means it will hit the sweet spot between comfort and support for back and side sleepers.
