Best mattresses for side sleepers looking to get cozy

A miserable mattress shopping experience inspired two Silicon Valley software engineers to found Tuft & Needle in 2012, promising their customers “quality craftsmanship without the gimmicks.” Their highly rated, medium-firm mattresses are popular on r/Mattress, where the vast majority of users gush about their premium support, softness, and durability, as well as the company’s customer service and overall value.
T&N mattresses contain three different layers of material: just-bouncy-enough T&N Adaptive® Foam for optimal pressure relief; a breathable cover for cool sleeping; and a high-quality support layer for all-night comfort. They’re designed to fit on virtually any box spring, platform, or frame, but can also be placed directly on the floor (if that’s your thing) without losing their shape.
One Redditor writes:

“3 years sleeping on a queen Tuft and Needle mattress here. Still love it just as much as the first night I had it. My husband, who had back pain, also loves it. Super easy process/delivery, affordable and comfortable. 10/10 would sleep again.”

No matter your sleeping style, no one likes waking up in a sticky knot of sweat-soaked sheets. Enter: the Leesa, a medium-firm foam mattress containing a recovery layer of memory foam, a support layer of dense foam, and two inches of LSA200 Foam Technology™. The latter’s microcell structure permits ample airflow to reduce moisture while providing enough support and pressure relief for even the most scrupulous of side sleepers. 
Specs aside, you’ll sleep even better on a Leesa once you find out what it does beyond the bedroom: The company donates one mattress for every 10 they sell, and has contributed more than 30,000 units to date.
If a Leesa sounds like the right mattress for you, head over to their website ASAP: One of their current deals will give you 10% off the model of your choice plus a free memory foam pillow.
Redditor Jonah-the-cat writes:

“My wife and I purchased a Leesa during their Black Friday sale and it has been wonderful from night one. [I am] a side sleeper and I sleep hot so I was worried about the temperature being too warm but I have not noticed it at all. We have a Malouf Sleep Tite protector on the mattress and that doesn’t seem to make it sleep hot either.”

Zinus’ main draw is its ridiculous affordability: You can get its California king-sized mattress for a fraction of the price of other brands’ twins. Impressively, though, this 16-year-old company from Seoul doesn’t sacrifice comfort to bring you a bargain. 
Designed to be as calming and cozy as a mug of green tea, Zinus’ 12-inch medium-plush mattress contains a two-inch layer of gel-infused memory foam featuring natural green tea extract and active charcoal for lasting comfort and freshness. This material upon several inches each of cloud-like comfort foam; body-conforming high-density foam; and durable, high-density base support foam, all of which is enveloped by a knit jacquard cover. Zinus recommends you place its mattresses on a box spring for extra support, but they’ll do just fine on the floor or a platform, too.

“I ordered a zinus gel foam mattress from amazon for about 300$ a little over a year ago- I love the thing! My old mattress was killing my sides, I would wake up with really bad hip pain that would linger through the day- this mattress has fixed that issue and is suuuupeer comfy :)”

“Life’s too short to be uncomfortable,” proclaims Purple’s slogan — which, fair! The company has taken that mantra to heart by scientifically engineering its mattresses with a unique material called Hyper-Elastic Polymer™, a grid-shaped, pressure-releasing, temperature-neutral, and nontoxic material that’s more than 20 years in the making. Originally licensed to makers of critical care hospital beds, shoe insoles, backpack straps, and toy balls, Hyper-Elastic Polymer™ makes every Purple mattress a triple threat of spine support, no-feel motion transfer, and free air flow. This cushioning technology forms the top layer of every Purple mattress; the rest of it is comprised of soft and medium-firm high-density polyurethane foam.
The medium-firm Purple.3 is the model considered to be best for side sleepers, as it conforms rather close to the body while maintaining a supportive density. Act fast, and you can take advantage of Purple’s limited-time offer that includes a free Purple pillow or sheets with every purchase.

The process of making a Sleep On Latex mattress begins in the forests of Sri Lanka, where rubber trees are harvested and turned into a strong, all-natural Dunlop latex foam called Pure Green®. This innovative material comes free of synthetic products and fillers, and boasts leading international health certifications so you’ll never lose sleep over your mattress’ makeup.
You’ll find a two-inch comfort layer and a six-inch base layer of Pure Green® latex inside every SOL model, each of which comes with a soft, airy cover made from organic cotton and organic New Zealand wool. SOL’s Medium mattress is ideal for side sleepers who weigh more than 225 pounds or so, as it provides thickness and firmness without being rigid or overly bouncy, and doesn’t sag with use.

“We purchased a King mattress from Sleep on Latex a little over a month ago and couldn’t be happier. I’m 6’2” and 230 lbs, and so far it’s been amazing compared to our old worn out spring mattress.”

Comfort, durability, natural cooling, and easy setup make The Original Mattress by Casper a great pick for a good night’s sleep, no matter what your sleeping position is. 
Great for back, side, and stomach sleepers, this Casper mattress has three foam layers — each one adding extra full-body comfort. The top layer is soft and made with cooling, breathable Airscape material to keep the night sweats at bay, the second zoned support layer minimizes aches and pains by cradling your natural curves and supporting pressure points, and the base layer rounds out the comfort factor by reinforcing the layers above, minimizing sinking and sagging while you doze off. Its durable construction means that out of all the online memory foam mattresses out there, it’s a bit firmer than other options you’ll find — so be mindful if you want a super soft mattress that has a lot of give. If that’s you, Casper may not be the best pick. 
The high-quality memory foam layers aren’t the only perk of the Casper mattress. It has a tough, removable cover made from recycled water bottles that’s built to withstand wear and tear for years to come (and a 10-year warranty if it doesn’t). Need assistance with mattress assembly? Casper offers in-home setup, where their team will hand-deliver the mattress to you, set up any products that require assembly, and remove all the packaging once they’re done so you can use your mattress right away.
If you’re not satisfied with your purchase, you can contact Casper for speedy and helpful customer service support, which many claim to be top tier in terms of customer problem-solving.
Paul, a Casper customer, writes: 

“From the delivery of the box to the magical unfolding of the king size mattress to the first time laying on the bed, all smiles here! I have traveled for work for years, often sleeping on different beds at different hotels night after night. None of those beds compare to our Casper Mattress and I’ve probably tried them all. Every time I climb into bed I smile and tell my wife I love our mattress. I think you will love it too.”

A medium-firm mattress (one of four models in Tempur-Pedic’s new TEMPUR-ProAdapt™ series), this bad boy guarantees “advanced adaptability and a truly personalized comfort and support experience.” This comes courtesy of its elite three-part structure, which contains a layer each of Tempur-Pedic’s cooling SmartClimate® Dual Cover System; its Original TEMPUR® Comfort Layer for perfectly supple support; and its TEMPUR-APR™ Support Layer for pressure relief.
While that $2,500+ price tag is straight-up formidable — and pretty unrealistic for the majority of mattress shoppers, if we’re being honest — Tempur-Pedic tries to make it easier on your wallet by offering a variety of sweet promos on certain orders. When we last visited its site, for instance, you could get a $300 instant credit with a mattress set purchase.

Probably the most notable thing about Saatva’s high-density Loom & Leaf mattress is that it has two different firmness options: Firm, and the more popular relaxed firm. 
If you’re on the heavier side, you know that memory foam beds are usually a little too soft, leading you to sink into the bed — a one-way ticket to back pain. The Loom & Leaf mattress makes up for this with its special high-density foam construction, keeping the mattress soft, but also adequately supportive, no matter your size. Also, due to its durable design, you’ll find that the bed doesn’t sag or deflate over time, which helps to maintain it’s supportive qualities.
The Loom & Leaf is able to achieve all that support by way of only four layers:

1. Quilted Organic Cotton Cover: Soft and flame retardant outer layer to keep you safe and comfortable.
2. Cooling Layer: Made from Saatva’s spinal zone gel and breathable foam to keep you cool with optimal lumbar support.
3. Eco-Friendly Foam Layer: Five pounds of cozy, supportive, eco-friendly memory foam that is naturally cool.
4. Breathable Support Layer: Firm, multi-layer support foam to provide additional deep contouring.

On top of all that, you’ll get free white-glove delivery, a 15-year warranty, and a generous 120-day trial. 

The Amerisleep AS3 is perfect for the in-between sleeper — the sleeper who likes some firmness, but also some softness. Comfort, but also ample support. It’s not always easy to find the best of both worlds, but Amerisleep succeeds in that. 
The AS3 also shines in the overnight recovery department, with great targeted pressure relief that’ll be beneficial to athletes, those whose jobs involve physical labor, and those of us who are simply prone to joint pain from regular daily tasks. It’s more responsive than your run-of-the-mill memory foam, offering better pain relief and bounce-back (keeping you from feeling “stuck” while you rest).
It gets the medium feel just right by evenly blending support and softness with its Hive layer, which contours to your body and soothes pain-causing pressure points. Plus, with added support under your head, back, and legs, you’ll experience enhanced spinal alignment (and extra cushioning under your hips and shoulders).
The Amerisleep AS3 also uses an eco-friendly, plant-based Bio-Pur material that keeps you cool through the night — its open-cell design allows more air to escape than traditional foam, making it effortlessly breathable and effective at wicking away warm air.
The mattress is long-lasting, too — it has an industry-leading 20-year warranty, a 100-night trial, and a guarantee to hold out against forming soft spots or sagging. 
If you want a mattress that sits nicely at the intersection of support and comfort, you won’t go wrong with the Amerisleep AS3.
