The Helix Midnight Luxe is the newer, taller and plusher version of the original Helix Midnight and has recently knocked its predecessor off the top spot of our best mattress for side sleepers buyer’s guide. The Midnight Luxe is a 13.5 inch tall hybrid mattress made with a mix of Helix Responsive Foam, Copper Gel Memory Foam, plus DuraFoam and up to 1,000 individually wrapped coils for enhanced lumbar support and four-sided edge support (something that was lacking slightly in the original). This enhanced support is topped off by an ultra plush pillow top cover, which is wrapped in a hypoallergenic Tencel cover (which is another upgrade on the original).  

Despite the deep pressure relief the pillow top provides, this is still a mattress that you sleep on top of as opposed to sinking too deeply into, thanks to the responsive memory foam layer underneath, which is underpinned by steel coils and dense foam base layer. Helix rates this mattress as 5-6 out of 10 on the firmness scale, but we rate it as a slightly firmer 6 out of 10, placing it in the true medium-firm category. This firmness, in addition to the enhanced lumbar support, means that it’s suitable for back sleepers, too. It’s plush, but surprisingly supportive. 

The Helix Midnight Luxe boasts outstanding motion isolation, which is great news if you’re a restless sleeper who shares their bed. The strengthened edge support means you can sleep up to and sit comfortably on the bed’s edge without it slowly feeling it dip or collapse beneath you (there is a bit of sink, but that’s down to the squishiness of the pillow top). 

In terms of temperature regulation, the Tencel cover is an improvement on the breathable cover included as standard on the Helix Midnight. It’s hypoallergenic and cool to the touch, and our testing panel felt comfortably cool throughout the testing period. However, if you're prone to overheating, you might want to upgrade to the GlacioTex cooling cover for an additional $249. Our only real niggle is the lack of handles on the side, which make moving this bed a little arduous. That aside, we highly recommend the Midnight Luxe if you want a plush hybrid bed for comfier, cooler side sleeping.

Materials: Memory foam, other foams, coils

Not the best for sleepers over 250lbs

Too soft for some tastes

The Helix Midnight is a highly rated hybrid, and it's our top affordable choice for  side sleepers guide thanks to the perfect amount of sinkage at the shoulders and hips to keep your spine in neutral alignment when you're snoozing in this position, at a competitive price. Our testers loved sleeping on this mattress and found that it delivered plenty of support for the lower back, too. 

At the top of the Helix Midnight mattress, you'll find a layer of blended memory foam that contours to your body and relieves pressure points when sleeping on your side. This works with various other foams to effectively deliver cushioned comfort. Don't worry – you won't feel as though you're being swallowed alive here, as the memory foam layer isn't hugely thick. Alongside these foams, the Helix Midnight mattress includes a layer of individually wrapped, 8" pocketed coils, which boost airflow through the mattress as well as limiting motion transfer within the mattress. That's great news if you've got a restless bedmate, as this bed will absorb motion and prevent their wriggling from disturbing your rest. 

You'll also find a range of temperature-regulating materials, which we found worked effectively to keep our testers comfortably cool at night. The soft-touch stretch cover stays cool to the touch, even during warmer weather, although very hot sleepers may wish to upgrade to the GlacioTex Cooling Cover for an extra $249. 

Rated 6/10 on the firmness scale, the Helix Midnight's medium softness offers the pressure relief you need around your hips and shoulders. However, it is on the softer side of what we'd recommend for side sleepers, and indeed being too soft is one of the main complaints from those people who didn't get on with this mattress. If you prefer a firmer feel, or if you also like to sleep on your front or sleep on your back sometimes, you should look for a mattress that's more like a 7 or even 8/10 (check out the Awara Natural Hybrid at #9 on this list). Note it also might not be supportive enough for those over 250lb (head to our best mattress for heavy bodies guide for recommendations there).

The best luxury mattress for side sleepers

Best mattress for side sleepers: The Saatva Classic mattress shown on a light wooden bed frame in a stylish bedroom

Saatva's best-rated luxury hotel mattress for side sleepers

Specifications

Type: Innerspring hybrid
Material: Pillow top, memory foam, coils, other foam
Firmness (1-10): 3, 5-7 or 8
Height: 11.5" or 14.5"
Trial: 365 nights
Warranty: Lifetime
Price bracket: Premium

Reasons to buy

+
3 firmness options to choose from
+
Luxurious feel and high build quality
+
Free white glove delivery

Reasons to avoid

-
$99 returns fee
-
Some slight motion transfer

If you prefer a more traditional innerspring feel, the Saatva Classic is well worth a look. There is a little bit of foam in this mattress (a thin layer to offer extra lumbar support in the middle third, and rails around the perimeter for stability), but the main body of the mattress is mostly springs, with a pillow top for cushioning. This is a mattress you sleep on top of, rather than sinking in too deeply. 

One big draw is that the Classic can be customized to your preferences, with two heights and three firmness levels to choose from. For side sleepers, we'd recommend either the soft (rated 3/10 on the firmness scale) or Luxury Firm (5-7), depending on your body weight and whether your preference is for a plusher or firmer feel. (We rank the 8/10 version as one of the best firm mattresses, but it likely cause pressure to build up in the shoulders for most side sleepers.) 

We tried out the Luxury Firm option and found it delivered fantastic pressure relief, with the dual-coil system providing buoyant, firm support, and a little bounce. We rate it amongst the best mattresses for back pain, too.

The abundance of springs inside this model provides plenty of space for air to circulate, and the Classic sleeps nice and cool, with no issues trapping heat. (This can be an issue with all-foam models.) If you want that memory foam feel but struggle with sleeping hot, check out the GhostBed at #8. 

Price-wise, this sits in the premium range, but the build quality is impeccable and there are perks like white glove delivery included for free. If you have the budget, the Saatva Classic is a worthwhile investment. As a slightly cheaper, yet still luxurious alternative, check out the Brooklyn model at #4.

Saatva Classic: $1,395 $995 at Saatva

Saatva Classic: from $1,395 $995 at Saatva
Our exclusive $400 Labor Day discount yields stronger prices for the Saatva Classic than the general Saatva mattress sale taking place right now. It reduces the cost of a queen size to $1,695 (was $2,095), which is tied as the lowest price we've seen for it this year. You'll get free mattress installation with old bed removal too, plus a year's sleep trial and a lifetime warranty. That's excellent value for a handcrafted mattress.

The best mattress for side and back sleepers

Materials: Memory foam, other foams

Takes a while to expand

Nectar's popular memory foam mattress offers a slight sink-in feel but with a more noticeable amount of firmness compared to squishier side sleeper mattresses like the Helix Midnight above. This medium-firm bed-in-a-box balances comfort and support brilliantly. It'll contour to the shape of your body to relieve pressure on your shoulders, hips and knees, so you won't wake up with aches and pains in those places, but it's still firm enough that you'll feel well supported. You won't sink deeply into this mattress, but you can still expect some cradling.

Our testers also found that the Nectar mattress does a brilliant job at minimizing motion transfer, so you won't feel your partner (or pet) move around in bed next to you. Because it's slightly firmer, it's also suitable for combi-sleepers who sometimes like to lie on their back or stomach, making it a versatile choice overall.

This bed is entirely foam (in fact, we think it's one of the very best memory foam mattresses you can buy). At the top, you'll find 3 inches of high-density gel memory foam, which Nectar has designed to work in tandem with 2 inches of adaptive response memory foam for extra support. At the base are 7 inches of standard foam to provide you with a sturdy sleeping space. 

All-foam mattresses can trap body heat and sleep warm. We didn't have any particular issues with this when we tried the Nectar, but if you know you sleep hot, consider the Cocoon (#3) instead. This is a similar all-foam design, but for a slightly higher price, you get a specialist cooling cover. Or if you have the budget, the GhostBed Luxe (#8) offers excellent cooling. 

The Nectar mattress also receives top marks for added extras: there's a 365-night mattress trial period and a Forever Warranty, which is the best you'll find anywhere. This mattress is basically never sold at MSRP – it's one of the best mattress in a box models when it comes to sheer value for money.

Nectar Memory Foam: $699 $349 at Amazon

Nectar Memory Foam: from $699 $349 at Amazon
We usually recommend buying straight from the manufacturer for the best aftercare, but Nectar no longer sells its original memory foam mattress since it's been replaced by the slightly redesigned Nectar Classic. There's unlikely to be a major difference in performance between the two, and most sizes are priced the same, but we've tested the previous Nectar Memory Foam Mattress and highly recommend it for side sleeping. Amazon has it for Nectar's standard sale price, with a queen costing $649 (was $899). Per the Amazon product page, Nectar's one-year trial and forever warranty should still apply.

The best memory foam mattress for side sleepers

Specifications

Type: Hybrid
Firmness (1-10): 6-7
Height: 9.25"
Trial: 100 nights
Warranty: 10 years
Price bracket: Upper-mid
Materials: Foam, GelFlex Grid

Reasons to buy

+
Great pressure relief for hips and back
+
Supportive with good spinal alignment
+
Sleeps cool

Reasons to avoid

-
Edge support could be better
-
Thinner option

If you tend to wake up with hip and knee pain from lying on your side, the Purple Mattress might well be the best option for you. We tested this mattress across all sleeping positions and it was particularly comfortable for side sleeping, thanks to Purple’s own Gel-Flex Grid technology; a durable hyper-elastic gel that flexes under pressure to deliver tailored support where you need it most.

While we found the edge support to be a little weak compared to similar mattresses, there's little else to complain about on the award-winning Purple Original. The combination of hyper-elastic polymer material and dual layers of foam reduce all pressure on your main impact points, and our testers felt supported from head to toe when sleeping on this mattress. It delivers good airflow too, making it an excellent choice for restless side sleepers who toss and turn at night because they’re overheating. 

We found it to have a true medium-firm feel; we didn’t sink in too much at the hips and back, so our spine stayed in neutral alignment and we didn't feel any stiffness upon waking up. Overall we found it supportive, comfortable and cool, and liked the responsive yet firm feel. You'll have 100 nights to trial it at home, with Purple refunding your money if you change your mind during the trial. 

Purple Mattress: $999$799 at Purple

Purple Mattress: was $999 now from $799 at Purple
For Labor Day, the Purple mattress sale knocks $200 off every size of the original Purple Mattress, which brings the price of a queen down to $1,299. This is an improvement over the $100 discount we saw previously, but it's been cheaper in the past. You'll still get free shipping and a 100-night trial.

The best budget cooling mattress for side sleepers

Trial: 100 days
Warranty: 10 years
Price bracket: Lower-mid
Materials: Memory foam, other foams

Reasons to avoid

Edge support not the best

GhostBed sleeps cooler

Nectar is similar + cheaper

Made by industry giant Sealy, the Chill is a medium firm, all-foam mattress that delivers a lot for a mid-range price. Our reviewers all agreed that it's especially well suited to side sleepers, providing plenty of cushioning and support in this position. An upper layer of memory foam contours comfortably to the sleeper's body to provide tailored support, although you won't sink in as much as you will with some of the other models in our list. 

The real star of the show is the phase-change material in the stretch-knit cover, which does a great job of regulating the temperature and wicking away heat. In our review, even our hot sleeper didn't wake up feeling sweaty once. (That cover is the main reason to choose the Chill over the Nectar (#2), an otherwise very similar mattress for a slightly lower price.)

While the Chill doesn't have quite the chilling powers of the GhostBed (at #8), it sleeps impressively cool for an all-foam model at a lower-mid range price. In fact it's excellent value all round – the Chill is far cheaper than most specialist cooling models, and we rank it amongst the best mattresses under $1,000.

The Cocoon by Sealy Chill also absorbs motion extremely well, making it a great choice for light sleepers who share a bed. We wouldn't necessarily recommend this model to heavier weight individuals, though, who may sink through the memory foam layer and not get those body-contouring benefit.

Cocoon by Sealy Chill:$619$374 with code EXTRA25 at Cocoon
EXTRA25

Cocoon by Sealy Chill: was $619 now from $374 with code EXTRA25 at Cocoon
There's 35% off the Chill, which is a standard Cocoon by Sealy sale, but the good news is that this mattress had an MSRP drop last year, so it's cheaper now than we've ever seen it. Add code EXTRA25 to shave another $25 off. After all discounts, a queen is $674, which is an incredible value. You'll take home up to $199 of free cooling pillows and sheets too.
