How we test
We research and test the latest mattresses for side sleepers to provide expert recommendations, then use our test data to rank them out of 10. Read our mattress methodology for more.

Some of this year’s best mattresses cater to side sleepers, as many of them are available to buy in soft or medium-firm comfort levels, have ample pressure relief, band enough firmness to ensure that your back and joints are in correct alignment. 

We have been gathering test data -- both from verified customer reviews and our very own expert mattress testing panel -- on the best mattresses for side sleepers for a number of years now, in order to compile a list of this year’s very best options. We have found that the best mattress for side sleepers is still the Helix Midnight mattress.  This all-foam mattress is designed specifically to meet the unique needs of side sleepers, offering pressure relief in all other right areas. You can read more about our findings in our Helix Midnight mattress review

While the Helix Midnight is a top choice for side sleepers, we have included the nine other mattresses that also ranked highly in this roundup. Mattress sales run all year around, but with Black Friday mattress deals arriving every day now ahead of the Cyber Monday mattress deals, there’s never been a better time to invest in a new mattress. 

Now, let’s take a look at the best mattresses for side sleepers, as reviewed by our sleep experts…

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 sits at the top of our best mattress for side sleepers guide because it offers the perfect amount of sinkage at the shoulders and hips to keep your spine in neutral alignment when you're snoozing in this position. 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). 

Helix Midnight: from 

Helix Midnight: from $936 $702.20 + a bedroom bundle at Helix

Helix is currently offering 25% off its mattresses, taking the price of a queen size mattress down to $999. This is likely to be Helix's best Black Friday offer, as Helix mattress sales usually take 20% and offer a free pillow set rather than a whole free bundle, so this is definitely the best time to buy.

The best hybrid mattress for side sleepers

Saatva's highest-rated hybrid 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 mattress: from $1,095 $695 at Saatva Head to Saavta using the link here and you can save up to $400 on the price of a Saatva Classic, with prices starting from $695. Their Black Friday deal is the best Saatva sale we've seen this year, as it is cheaper than the regular deal prices (typically you'll pay $1,995 for the queen, and evergreen sales usually drops the price to $1,695), so now is definitely the best time to buy. 

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.

The best pressure relieving mattress for side sleepers

The best side sleeper mattress if you have aching joints

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: was

Purple Mattress: was $799 now from $599 at Purple
This new Purple mattress deal is better value on the larger sizes of the Purple Mattress, reducing the price of a queen size to $1,199 (last month it cost $1,259). That means a saving of $200, making now is the best time to buy the Purple Mattress if you need a new bed urgently and can't wait for Black Friday to see if prices drop further. You'll also get free shipping and a 100-night trial too.

The best budget cooling mattress for side sleepers

Best mattress for side sleepers: Cocoon by Sealy Chill Hybrid mattress in a bedroom

The best cooling mattress for side sleepers on a budget

Specifications

Type: All foam
Firmness (1-10): 6
Height: 10"
Trial: 100 days
Warranty: 10 years
Price bracket: Lower-mid
Materials: Memory foam, other foams

Reasons to buy

Specialist cooling cover works well

Excellent support

Reasonably priced

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: was

Cocoon by Sealy Chill: was $619 now from $399 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 early this year, so it's cheaper now than we've ever seen it. A queen is $699, which is incredible value. You'll take home up to $199 of free cooling pillows and sheets too.

Lacks support for heavier bodies

The Amerisleep AS3 is a medium firmness mattress that's perfect for side sleepers. It's available in all-foam and hybrid versions – we tested the latter and were very impressed. The comfort levels are made with Amerisleep's proprietary Bio-Pur foam, which is made from plant materials and offers comfortable cushioning around the shoulders and hips – perfect for side sleeping. We also found this foam delivered much better temperature regulation than other mattress foams we've tested, making this a solid choice for hot sleepers.

Beneath the foam is a layer of pocket coils, which help add firmness. However, side sleepers who weigh over 250lb should approach with caution, as this mattress likely won't provide enough support. Combi sleepers should also be aware this mattress will probably be a little too soft for back / stomach sleeping.

The coils along the sides of the mattress are extra-sturdy, and in our review, we were impressed by the edge support on the AS3 Hybrid. That's good news if you want to be able to spread out over the whole mattress. Motion isolation is also excellent, meaning you won't be disturbed if your partner is a restless sleeper.

Discounts in the region of $450 off of a queen size Amerisleep AS3 mattress are not unusual, but it is still a great price. It’s difficult to predict whether this discount will be topped when the Black Friday deals drop at the end of November, but we wouldn’t bet on it.

Temperature affects firmness

The GhostBed Luxe specializes in keeping sleepers cool. It's a little softer – we rate it a 6 out of 10 firmness in our tests – and well-suited to lighter-weight side sleepers who spend half the night kicking off the covers because they feel too hot to sleep through. It's also a good choice for couples as it provides excellent motion isolation.

Hot sleepers will be drawn to the Ghost Ice fabric quilted cover that helps the surface stay cool to the touch. This is followed by a 1-inch slab of gel memory foam to deliver a cozy body hug feel. After that comes an extra airflow-boosting layer, but we're most excited by the Ghost Ice Layer; it uses thermo-sensitivity tech to sense heat and keep the core of the mattress cool. None of our testers ever felt warm when sleeping on the GhostBed Luxe so the tech absolutely works.

There's an additional 2 inches of gel memory foam further down to relieve pressure points, followed by 2 inches of GhostBounce foam to contour to your body, with a 7.5-inch slab of high-density support foam at the base to help the mattress last for many a year to come. Edge support and motion isolation are also top-notch. Those who want a luxury mattress with a slow-moving feel will find this to be one of the best mattresses for side sleepers without question.

When you’re buying a mattress with the word 'Luxe' in the title, you can normally expect a softer feel and a heftier price tag. You get both here, although constant sales mean you can ignore the MSRP. If it's out of your budget but still want a cooling mattress, check out the budget-friendly Cocoon Chill (#3) or the mid-range Purple (#5).

GhostBed Luxe: from $2,595 $1,298 at GhostBed
