A memory foam mattress is comfy, supportive, and indulgent. But a memory foam mattress can also come at a high cost. Luckily, there are budget-friendly options available, and you don't have to pay an arm and a leg to get a great night's sleep.

In the MOOZ Reviews Lab, we've tested hundreds of mattresses and mattress toppers. When testing memory foam mattresses, our testers evaluate temperature, pressure relief, durability, and bounce. We score firmness, temperature, bounce, comfort, feel, and pain relief. These are the best memory foam mattresses of 2022 that scored highest overall and in each aspect of our tests.

King Size Mattress, Molblly 12 inch Cooling-Gel Memory Foam Mattress in a Box, Breathable Bed Mattress for Cooler Sleep Supportive & Pressure Relief, 76

Molblly King Size Mattress

{EASY SHIPPING & SET-UP}: Mattress is compressed and packaged in a box for shipping, allowing it to easily be delivered to your door and expand to its full lofty shape inside your home. They fit all frames, such as box spring, floor, slatted base, flat platform or adjustable bed, hospital bed.

The Molblly was our favorite budget pick over a year ago, and it's still a great choice for most people. New for 2019, the 12-inch model has a larger, softer sleep surface, and a denser foam base. It's much more responsive, with faster cooling and response time. It retains its shape and responsiveness over time, and remains comfortable and breathable. The foam has held up well, and it's still soft and comfortable. Molblly mattresses are an affordable option for a wider range of people, and at this size they work in most rooms, though we recommend using it on a firmer surface. We loved the setup and easiness; the mattress comes in a box, you unfold it, and it's all ready to use. It has several good features, including sensors that shut off a fan or heat if there's something wrong with the mattress. It's a good choice for anyone who needs a fluffy mattress, and for anyone who wants something that will last and can be easily moved around.

LUCID 10 Inch 2020 Gel Memory Foam Mattress - Medium Plush Feel - CertiPUR-US Certified - Hypoallergenic Bamboo Charcoal, King

LUCID 10 Inch 2020 Memory Gel Foam Mattress

by LUCID

This mattress features a 10-inch MEDIUM-PLUSH feel profile for universal comfort for side, back, and stomach sleepers

The LUCID 10 inch memory foam mattress does exactly what it promises. The mattress has 2.5 inches of plusher, gel-infused memory foam on top of 5.5 inches of dense, supportive foam. The mattress is 10 inches thick, but it feels slightly thinner than that because of how thick the top layer is. The mattress is also fairly firm, which meant we slept noticeably better on this mattress than on our prior memory foam mattress. The LUCID 10 inch has more give than our other pick, the Nectar memory foam mattress, but the difference is minor. The Nectar mattress is slightly more comfortable, but the LUCID mattress is cooler to sleep on, and we think it provides better spine alignment. Plus, the Nectar mattress is 7.5 inches shorter and 3 inches narrower.

Classic Brands Cool Gel Ventilated Memory Foam 12-Inch Mattress | CertiPUR-US Certified | Bed-in-a-Box, King

Classic Brands Cool Gel Ventilated Foam Memory 12-Inch Mattress

by Classic Brands

Mattress ships compressed, rolled and shipped in a box conveniently delivered to your door for easy set-up; frame/foundation/base not included

The Classic Brands Cool Gel Ventilated Memory Foam 12-Inch Mattress is a great, affordable mattress with gel memory foam. It's rated to last 10 years, and it does a nice job of conforming to your body shape as you sleep. The cool gel layer helps regulate temperature, and the memory foam is thick, so you feel supported and comfortable. But if you're used to sleeping on a traditional mattress, it may take some getting used to. The memory foam offers some bounce, so you may feel too restless on the Cool Gel Ventilated Memory Foam 12-Inch Mattress. Also, the Cool Gel Ventilated Memory Foam 12-Inch Mattress doesn't pass our test for durability. The side-stitching didn't hold together, and the foam started to sag in the middle. If you're on a budget, and you're looking for a memory foam mattress, the Classic Brands Cool Gel Ventilated Memory Foam 12-Inch Mattress is a good choice.

Olee Sleep 10 Inch Gel Infused Layer Top Memory Foam Mattress, King, Blue

Olee Sleep 10 Inch Gel Layer Infused Top Memory Foam Mattress

by Grantec Co., Ltd

Any new product will expand within minutes and can have a mild scent upon unboxing that will dissipate in a few hours in a well-ventilated room | Remove packaging within 72 hours, and allow an extra 48-72 hours for proper decompression

This mattress is firmer and thicker than other mattresses we tested, so it's best suited for people who sleep primarily on their stomach or back. The combo of firm and cool foams, plus the presence of gel-infused foam, does an excellent job of supporting your body and regulating the temperature. The mattress sleeps cool to the touch, and it's very comfortable. The top layer is 7 inches thick, and the middle layer (innerspring) is 5 inches thick. The mattress is nicely balanced, and it's very supportive while still being soft to the touch. If you're a heavy person, or if you tend to sleep on your stomach or back, the Olee Sleep mattress will suit you well.

Milliard Memory Foam Mattress 10 inch Semi-Firm, Classic (King) 76x80x10 in.

Milliard Memory Foam 10 Mattress inch Semi-Firm

by Milliard

Convenient - The beautifully designed cover is removable and machine washable for easy care.

The 10-inch Milliard Memory Foam Mattress blends performance and affordability, making it a good bet for the casual sleepers who want a middle of the road mattress but aren't interested in spending a fortune. While its price suggested a medium-firm mattress, Milliard's 2.5 inches of memory foam on top seemed to deliver more of a softer-firm feel. The mattress should live up to its manufacturer's 2-5-year warranty. Milliard's better-known competitors, Casper and Leesa, offer similar mattresses that come with a 10-year warranty.

Zinus 10 Inch Green Tea Memory Foam Mattress CertiPUR-US / Certified / Bed-in-a-Box / Pressure Relieving

by Zinus

EXPERTLY PACKAGED - Our technology allows this mattress to be efficiently compressed into one box thats easily shipped and maneuvered into the bedroom; simply unbox, unroll and this mattress does the rest, expanding to its original shape within 72 hours

If you're looking for a mattress on a budget, the Zinus Green Tea Memory Foam Mattress is a solid choice. This is on the low end of the price spectrum for memory foam mattresses, and it's comparable to online-only brands like Leesa. If you like memory foam but don't need the extra inches of memory foam that are typically found in high-end mattresses, we recommend this one. Zinus is known mostly for its affordable memory foam foundations, but it's now making memory foam mattresses as well, and the Green Tea Memory Foam Mattress is no exception. While the Zinus mattress was a little firmer and firmer than we expected for a bed-in-a-box mattress, it performed well in all of the categories that matter, including pressure relief (it offers a comfortable, firm feel that's also soft enough to cradle your shape), durability (we had the mattress for 10 months before we had any issues), and support (it's fairly good at keeping sleepers aligned with their spines). Its firmness makes it a better choice for side sleepers than back sleepers, but its soft, airy surface makes it a good choice for back sleepers as well.
