Helix Midnight Luxe mattress review: Unbeatable comfort and support for side sleepers

Helix Midnight Luxe Mattress review in brief

The Helix Midnight Luxe is a luxury hybrid mattress designed for side sleepers — although it's versatile enough to support back sleepers, as well. That's just one of the reasons why it's earned a spot in our guide to the best mattresses for all sleepers and budgets.

In our opinion, it's a well-deserved spot. We tested every inch of the Midnight Luxe per our mattress testing methodology, assessing its performance against key factors that come into play when choosing a new mattress — motion isolation, edge support, and pressure relief (very important for side sleepers).

Of course, comfort is subjective, so we also had a band of expert mattress testers — comprising people with different body types and sleep needs — try this mattress. That includes our lead tester, who slept on the Midnight Luxe for a months-long stretch at her home, and another tester with back pain who slept on a version with the ErgoAlign support layer during a hotel stay.

Below you'll find our in-depth review of the Midnight Luxe. If you only have time for the highlights, here’s our Helix Midnight Luxe Mattress review in brief…

The Helix Midnight Luxe is a hybrid mattress that stands at a statuesque 13.5” tall, with a navy and white colorway that's befitting of even the most luxurious of hotels. But it’s what’s underneath the covers that makes the Midnight Luxe so impressive.

Our lead tester — who shares her bed with her partner (and sometimes their children and cat) — called in a queen-size Helix Midnight Luxe for testing. While Helix rates this mattress as 5-6 out of 10 on the firmness scale, our panel of testers felt it was slightly firmer and rated it as 6 out of 10, placing it in the true medium-firm category.

As an average-weight side sleeper, our lead tester found that the plush pillow top layer absorbs pressure from around the shoulders, hips, and knees. You won't need to shift positions in the night due to an achy shoulder or dead hips. Additionally, our lead tester's partner, a heavier-weight back sleeper, also felt comfortably supported when lying on both his back and side.

This is because the Midnight Luxe's plush pillow top is underpinned by high-density memory foam, responsive foam, and up to 1,000 steel coils. This all works in tandem to hold you on top of the mattress, as opposed to sinking deeply into it.

If back pain relief is a major motivator in buying a new mattress, consider the ErgoAlign upgrade ($249 at MSRP). This is a tri-zoned foam layer that's firmer in the center to aid alignment. One of our testers slept on this version of the Midnight Luxe during her travels and enjoyed pain-free mornings as a result.

As well as appealing to both side and back sleepers, another big tick for couples with different sleep styles is the bed's ability to isolate motion incredibly well. Despite children climbing in and out of bed in the middle of the night, there's very little motion transfer, which is great news for anyone who shares a bed.

Support around the edge of the bed is reliable. Again, that's largely due to the individually wrapped coils that bolster the perimeter. Our lead tester did feel a little bit of sink when sitting on the bed's edge, which we're putting down to the squishiness of the pillow top. Otherwise, she could sleep right up to the bed's edge without feeling like she would tip out.

We've tested the Helix Midnight Luxe during heatwaves and cold snaps. The breathable Tencel cover kept us cozy in the winter and — while not cooling as such — at a comfortable temperature in the summer. However, hot sleepers have the option to upgrade to the GlacioTex cooling cover for an additional $249 at MSRP, or the new CoolForce layer crafted from graphite ribbons to draw heat from the body, which costs an additional $499 at MSRP.

Price-wise, regular Helix mattress sales mean that a queen Midnight Luxe retails in the region of $1,918 (more on pricing and when the best time to buy is below). Standard shipping within the US is free and fast, but FedEx will only deliver to your front door. After teaming up with delivery firm LoadUp, you can now add on mattress setup and removal options; prices vary and depend largely on your location.

Having tested (and re-tested) the Helix Midnight Luxe, we highly recommend the Helix Midnight Luxe for side and back sleepers looking for the right balance of comfort and support. It's durable and well-made. We rate it as one of the best hybrid mattresses you can buy.

Helix Midnight Luxe Mattress review: Price & trial

• Typical discounts range between 20% and 25% off
• The best sale is 27% off with free bedding bundle
• It comes with a 120 night sleep trial and limited lifetime warranty

Helix mattress sales typically range between 20% and 25% off throughout the year. However, that discount tends to rise to 27% off during major events, like the upcoming Black Friday mattress sales. (That's often courtesy of a semi-exclusive discount code.)

Sometimes, Helix will include free items with purchase — either a couple of pillows or an entire bedding bundle. When it comes to buying the Helix Midnight Luxe at the best possible value, timing is everything.

Here’s the current MSRP and sale pricing for the Helix Midnight Luxe mattress:

• Twin MSRP: $1,436 (usually on sale for $1,149)
• Twin XL MSRP: $1,686.66 (usually on sale for $1,349)
• Full: $2,061.33 (usually on sale for $1,649)
• Queen: $2,398.66 (usually on sale for $1,918)
• King: $2,924 (usually on sale for $2,339)
• California king: $2,924(usually on sale for $2,3399)
• Short queen: $2,398.66 (usually on sale for $1,918)
• RV king: $2,924 (usually on sale for $2,339)

As well as regular mattress sales, you'll get a 120-night sleep trial, a limited lifetime warranty, plus free and fast shipping when you buy the Helix Midnight Luxe. There is also an option to upgrade to white glove delivery through a third party, with prices and availability depending on your location.

Those sleep benefits are decent, but fall slightly short when you compare them against a similarly priced mattress with a similar spec: the Saatva Classic. In contrast, you'll get a 365-night sleep trial with the Classic, a limited lifetime warranty, plus a free white glove delivery.

That's not to say that the Luxe's benefits are at all lacking, but if a lengthy sleep trial and free mattress installation (and removal of your old one) appeals to you, then shop around (and check out our Saatva Classic mattress review.)

Helix Midnight Luxe: twin was $1,436 now $1,048.28 with TOMS27 code at Helix Sleep
There's currently 27% off the Helix Midnight Luxe mattress in the Black Friday sale when you use our TOMS27 code at the checkout, bringing the price of a queen down to $1,751 (was $2,398). This is the cheapest you're ever likely to see this outstanding side sleeper mattress, and this price won't be around for long, so our advice is to get on this deal sooner rather than later.

Helix Midnight Luxe Mattress review: Design

• At 13.5", it’s two inches taller than the Helix Midnight
• 6 comfort layers, comprising of memory foam, foam and coils
• Zoned lumbar support coils for pressure relief

At 13.5 inches tall, the Helix Midnight Luxe is 2 inches taller than the Helix Midnight, which sits in the brand’s Core range. This height difference is crucial, as a depth of between 12 and 14 inches is considered an optimum depth for supporting the side sleeping position.

Like other beds in Helix’s Luxe collection, the Midnight comes with a breathable, hypoallergenic Tencel cover. However, you also have the option to upgrade to a cooling GlacioTex cover for additional temperature regulation, or a GacioTex cooling cover with additional CoolForce layer that is crafted from graphite ribbons to draw heat from the body.

There is yet another optional upgrade; the ErgoAlign layer. This is a zoned top layer featuring ultra dense foam around your mid section, designed to support and release pressure from your lumbar region.

For the purpose of this review, we tested a queen size mattress with the hypoallergenic Tencel cover, but also got the opportunity to spend four nights on a Helix Midnight Luxe with the inclusion of the ErgoAlign layer. For closer analysis on this layer, and whether we think it's worth the additional $249, scroll down to our comfort and support section below.

Beneath the Tencel cover is a premium quilted pillow top sewn into the top of the mattress, which provides an elevated, cloud-like feel. Underneath is a dense layer of responsive foam which helps give the bed its medium firmness rating. Next up, there is a layer of copper gel-infused ultra responsive memory foam for optimal support and stability.

We then reach the layer of durable steel coils, of which there are up to 1,000 within the Midnight Luxe. This advanced lumbar support provides reinforced support beneath the hips to help keep your spine in healthy alignment as well as bolstering the support around the bed’s edge. At the bottom, a dense layer of foam provides the base support of the mattress.

It is worth noting that this bed expands incredibly quickly (within 30-45 minutes), so we would advise making sure your mattress is where you’d like it (and the right side up) before removing it from the box. Its depth, plus weight (between 95 lbs - 125 lbs, depending on the mattress size), make it difficult to maneuver. However, since adding handles in a recent design-refresh, this process is now much easier.

Helix Midnight Luxe Mattress review: Comfort & support

• Premium pillow top offers exceptional pressure relief
• We rate this mattress as 6 out of 10 for firmness
• Supportive enough to sleep comfortably on your back, too

The Helix Midnight Luxe has been crafted specifically with side sleepers in mind, but is supportive enough to sleep on your back, too. And that's down to the bed's combination of its plush premium pillow top, closely followed by its ultra responsive memory foam.

During both stints sleeping on the Midnight Luxe, our side-sleeping lead tester experienced cloud-like comfort across her shoulders, hips and knees. What’s more, she didn’t experience any of the dreaded 'dead hip' she is prone to getting when sleeping on her side for too long, which meant she was comfortable enough to stay sleeping on her side throughout the night.

However, a separate member of our testing panel, a side sleeper with mild scoliosis and recurrent lower back pain, spent four nights sleeping on a Helix Midnight Luxe with ErgoAlign during a stay at the Fairmont Scottsdale Princess in Scottsdale, Arizona, courtesy of 3Z Brands, the parent company of Helix. Unusually for her, she found most benefit from the inclusion of the dense foam support layer when sleeping on her back.

"I’m typically a side sleeper and found Midnight Luxe comfortable in that position. (I also slept on my stomach at points, which felt fine.) However, by the end of my stay, I was waking up on my back — a position I rarely find myself in," she notes. "Thanks to the Midnight Luxe's reinforced lumbar support (the dense foam in the ErgoAlign centre, firmer pocket coils in the middle) and the cozy pillow-top, I couldn't help but shift onto my back and feel the tension melt away.

Given my history of back problems, sleeping on my back is probably a good habit for me to develop. Yet, no other mattress (or topper) I’ve tried has made me enjoy it as much as the Midnight Luxe With ErgoAlign did."

Regardless of whether you sleep on your side or back, the plush pillow top offers blissful cushioning across the touch-points of the mattress, which — alongside the responsiveness of the upper foam layer — provides blissful body cradling comfort. However, it's worth repeating that this is by no means a soft bed and, thanks to the inclusion of up to 1,000 individually wrapped steel coils and copper-infused memory foam, it provides plenty of support that holds you on top of the bed, as opposed to sinking too far into it.

The steel coils work in tandem with the foam layers to effectively provide enhanced lumbar support and pressure relief. As well as keeping the spine cradled in healthy alignment when side sleeping, this ergonomic support meant that our lead tester’s heavier back-sleeping partner felt comfortable and supported while sleeping on his back, making this a good option for combination sleepers.

Helix Sleep places the Midnight Luxe as slap bang in the middle for support at 5-6 out of 10 for firmness, but we would rate it slightly firmer at 6 out of 10. However, stomach sleepers will likely find this mattress to be too soft to adequately support their spine when sleeping on their front. If you want a firmer mattress that performs well for side and stomach sleeping, we recommend the Nectar Memory Foam Mattress instead (read our Nectar Mattress review for more).

Pressure relief score: 5 out of 5

Helix Midnight Luxe Mattress review: Set up

• Free and fast shipping within 3-5 days in the US
• Arrives in box and expands within 30-45 minutes
• No obvious off-gassing during unboxing

Delivery on the Helix Midnight Luxe is free and fast within the US. As we'd expect from one of the best mattress in a box brands in America, the Helix arrives vacuum packed and neatly rolled into a box for easy transportation. Unlike some other premium mattresses, White Glove Delivery isn’t included in the delivery.

However, Helix has recently teamed up with delivery firm LoadUp, which means you can arrange to have your mattress set up in your chosen space, as well as arranging the removal of your old bed. Prices for this service depend on your location and should be arranged at checkout - just enter your zip code for an estimate.

Given how heavy the Midnight Luxe is (between 95 lbs — 125 lbs, depending on the mattress size), the option to upgrade your purchase to include in home set-up is useful — but could work out expensive. If you want a good side sleeper mattress but would prefer a brand who ships direct to your bedroom and installs your new mattress for free, try the Saatva Classic instead.

Our box arrived incredibly damaged, but we believe that would have happened during shipping. Despite the damage to the box, the mattress had its plastic wrap still intact and was undamaged inside.

When we read that the Helix would take just 30-45 minutes to fully inflate, we were skeptical. The rate of expansion differs from each mattress and depends largely on the materials and components used, but other mattresses in a box usually take between 4 and 72 hours to fully expand. However, once we started unwrapping the mattress, it immediately began to take shape and had fully expanded within the specified time.

Some mattresses in a box can emit a strong odor after being vacuum sealed. This is called mattress off gassing, and is essentially any Volatile Organic Compounds (VOCs) being released into the air after being sealed. (Strong mattress off gassing is an indication of higher levels of VOCs, which is bad news for your health.) Despite having a sensitive sense of smell, our lead tester didn’t detect any obvious off-gassing.

Helix Midnight Luxe mattress review: Performance

• Dense memory foam layers dampens motion across the mattress surface
• Tencel cover provides reliable temperature regulation, plus cooling upgrade options available
• Support around the perimeter of the mattress is reliable

Our lead mattress tester initially slept on a queen size Helix Midnight Luxe mattress for seven weeks. As part of Tom’s Guide’s rigorous mattress testing methodology, we carried out a series of objective tests in order to gauge three specific areas of performance — motion isolation (a term to describe how well a bed absorbs movement), edge support (how sturdy the perimeter of the mattress is), and temperature regulation (how well the mattress regulates temperatures and prevents overheating).

Here's what we discovered:

Motion isolation 

As someone who shares their bed with a partner (and often their two kids and cat), motion isolation is a keen area of performance for our lead reviewer. The Helix Midnight Luxe absorbs motion throughout the mattress incredibly well, which meant that our lead reviewer (a self-confessed restless sleeper) wasn’t disturbed by any movement elsewhere in the bed throughout the night.

In order to cross reference the Helix Midnight Luxe’s motion isolation against that of other mattresses, our lead tester then carried out a series of drop tests. We dropped a 10lb weight from a 6 inch height on the surface of the mattress, placing a wine glass 4 inches, 10 inches and then 25 inches away. We observed both the movement of the wine glass, and how quickly the weight settled into place.

When dropping the weight 4 inches away, the glass wobbled but didn’t fall over. When we did the drop a second time from 10 inches away, the wobbled again, but less so. When we dropped the weight from a distance of 25 inches away, the wine glass barely moved. In all instances, the 10lb weight bounced once before settling.

These results mirror the findings our lead tester experienced during the testing period during which she and her family slept on the mattress, that the Helix Midnight Luxe handles motion isolation incredibly well.

Motion isolation score: 4.5 out of 5

Temperature control 

The Helix Midnight Luxe comes with a breathable Tencel cover that is derived from Eucalyptus feels cool to the touch. During our stints of sleeping on the standard Tencel cover, we didn’t overheat at any point, nor did we feel like our temperature was steadily rising throughout the night.

However, it is worth noting that our lead mattress reviewer wouldn’t describe herself as a particularly hot sleeper. That said, our secondary mattress tester slept on the Helix Midnight Luxe for four nights in Arizona during September and also reported that she maintained a comfortable temperature throughout the night.

If you are a particularly hot sleeper, there are now two separate cooling upgrade options with the Helix Midnight Luxe. The GlacioTex cooling cover, which costs an extra $249 across all mattress sizes at full MSRP, or the GlacioTex cooling cover and a graphite-infused CoolForce layer that works to draw 22% more heat from the body over a 12 hour period. This costs an extra $498.66 for all sizes at full MSRP.

That said, if sleeping hot is your primary sleep concern, we would recommend checking out our Bear Elite mattress review instead. It comes in three firmness options so is comfortable for all sleepers, has zoned lumbar support for back pain relief and, like the Luxe, isolates motion incredibly well. However, with a usual queen sale price of $1,578, it works out as better value than upgrading to Helix's specialist cooling covers. (And we also rate it as our best cooling mattress on the market.)

Temperature control score: 4.5 out of 5

Edge support 

Edge support is a term to describe the sturdiness of the perimeter of a mattress. Sturdy edge support is an important feature for any mattress, as it allows you to sleep right up to the bed’s edge, or safely sit before standing without feeling as though the mattress is dipping or collapsing beneath you.

Image 1 of 2

Helix Sleep states that the Midnight Luxe features full perimeter edge support for added stability. To evaluate this claim, we placed a 50lb weight along the mattress’s perimeter and measured how far it sank.

When positioned on the side, the weight sank about 3", and when placed at the foot of the bed, it sank 2.75". On a few occasions, the weight began to roll forward, though this may have been influenced by the plush, pillowy feel of the pillow top.

When sleeping on the mattress, our lead reviewer was able to sleep comfortably right up to the edge without experiencing any sinking or dipping. She also felt well supported when sitting at both the side and foot of the mattress. Other testers agreed, noting that the mattress felt reliably sturdy when sitting on the edge before standing up.

Edge support score: 4 out of 5

Helix Midnight Luxe Mattress review: Customer reviews

• 4.5 out of 5 stars from over 7,600+ verified customer reviews (October 2025)
• Critics deem the Helix Midnight to be softer than expected
• 5 star reviews cite its outstanding lumbar support

At the time of this update (October 2025), there are 7,600+ verified customer reviews on the Helix Sleep website, giving an average rating of 4.5 out of 5 for the Helix Midnight Luxe mattress.

Many of the 5 star ratings laud the bed’s plush but supportive sleep surface, which they believe provides deep pressure relief for their side sleeping position. Elsewhere among those 5 star reviews, those who share a bed find it comfortable and supportive for all different sleep needs (we rate the Luxe as one of the best mattresses for couples for this reason.)

Other satisfied reviews cite its lumbar support as helping reduce or eliminate back and neck pain, while others recommend the Midnight for both back and side sleepers.

From the relatively small pool of one and two star ratings, the main criticisms are that the mattress is softer than expected while a smaller still minority feel the mattress is much firmer than expected. There were also several criticisms surrounding the Midnight’s temperature regulation, with some complaining of overheating despite investing in the GlacioTex cooling cover.

Most recent reviews praise the 'perfect' balance of plushness and support, and some go as far as to say they're 'obsessed' with this mattress.

Should you buy the Helix Midnight Luxe Mattress?

The Helix Midnight Luxe provides outstanding pressure relief, crafted specifically for side sleepers. However, we found it to be as comfortable and supportive for back sleepers, too.

The inclusion of a plush, pillow top, and enhanced zoned lumbar support makes it worth the price hike from the Helix Midnight, which, taking into account current discounts, costs $973 for a queen. You can read our Helix Midnight mattress review for a closer analysis of the Luxe's more affordable predecessor.

Motion isolation is also very strong, which will appeal to restless sleepers who share a bed. Temperature regulation is decent, but could be worth splashing out on the GlacioTex cooling cover if you're an especially hot sleeper. Edge support has been bolstered around the bed's perimeter, so you can sleep comfortably right up to the edge, or safely sit before standing.

After experiencing the Helix Midnight Luxe with ErgoAlign firsthand, we would recommend paying the additional $249 at MSRP for those with significant back pain. However, even without the ErgoAlign layer, we deem the Luxe to be one of the best mattresses for back pain, due to its pressure relief and enhanced lumbar support.

In short, if you're predominantly a side, back, or combination sleeper who shares a bed or experiences back pain, then the Helix Midnight Luxe is an excellent mattress for you. The outstanding pressure relief, motion isolation, and zoned lumbar support make it an excellent choice.
