Original Mattress

We named this T&N mattress the best mattress you can find on Amazon in Good Housekeeping's shopping guide to the best mattress of 2023. Thanks to Prime Big Deal Days, you can buy our experts' favorite Amazon mattress for under $800 — plus reap the rewards of fast shipping. The mattress has the brand's Adaptive Foam technology that's designed to be durable and supportive without feeling too stiff. One five-star Amazon reviewer even writes, "'Ahhhh!' every time I get in bed! I can't tell you what a relief (dare I say blessing?!) it has been to sleep more soundly and not wake up in pain! We were so happy with this bed we ordered another one this spring for our spare room."

Sleep Element Mattress

Casper is practically akin to a "mattress-in-a-box," making it ideal for individuals looking for a mattress that's easy to set up and requires no additional help from White Glove services. Plus, the Element Mattress has one layer of memory foam designed to mold to your body as well as a supportive base. The brand recommends waiting 24 to 72 hours for your mattress to reach its full shape, but after that, you can crawl into bed and snuggle up with one of our favorite comforters.

Memory Foam and Innerspring Hybrid Mattress

Regardless of which mattress size you choose, whether that's a twin for the kid's bedroom or a California King for yours, experience the comfort of memory foam with the bouncy feel of durable steel springs. We appreciate the multi-layer design and the long-lasting materials that make up the Linenspa mattress's 8-inch height. The mattress has a 4.5-star rating on Amazon with more than 135,000 customer reviews.

14-Inch Hybrid Queen Mattress

This 14-inch hybrid mattress boasts multiple layers of pressure-relieving foam paired with buoyant wrapped coils, promising an ideal balance of softness and support. It's currently 23% off for Prime Day and even comes with a 10-year warranty to ensure you sleep soundly for years to come. Per the manufacturer, it's hypoallergenic and made from Certi-PUR US-certified foams.

Ventilated Memory Foam Mattress

If you sleep hot, consider opting for a cooling mattress like this one, which contains gel particles interspersed in high-density memory foam. This creates an ideal sleeping surface that conforms to your body and supports your back. Though memory foam tends to sleep hot, this one helps reduce that effect with cool gel that’s designed to draw heat away from the body and ventilation that helps with circulation. One five-star reviewer writes: "This mattress is so comfy, you'll feel like you're sleeping on a cloud made of marshmallows!"

Gel Memory Foam Mattress

This Amazon's Choice mattress is 10% off during Prime Day, and more than 56,000 customer ratings suggest you won't be compromising on comfort thanks to its affordable price. The mattress has 5 inches of memory foam, with 2 inches of gel memory foam and 3 inches of comfort memory foam, plus another 7 inches of layered dual foam.

Hybrid Mattress in a Box

Hybrid mattresses give you the best of both worlds thanks to a lovely combination of cushioning memory foam and innerspring coils for ultimate comfort and support. This mattress by Coolvie has a knit fabric cover and a five-zone spring system that's designed to work in harmony with the foam layer. The spring layer uses individual coils, which typically feel more comfortable than traditional innersprings. A 4.5-star rating on Amazon combined with an affordable price point makes this hybrid mattress a reviewer favorite.

Green Tea Memory Foam Mattress

An Amazon #1 Bestseller for a reason, this mattress has a unique memory foam formula that includes a gel-infused top layer that keeps you feeling comfortable. The multiple foam layers are encased in a knit fabric cover, and one of our consumer testers found the mattress to be just right, saying it was "not too hard and not too soft."

Please note: There’s currently a class-action lawsuit filed against Zinus as users are saying they unzipped the mattress and found fiberglass, which can lead to health issues and product damage. We spoke to a Zinus spokesperson who advised customers to follow label instructions and contact customer service if they have questions or concerns.

GelFlex Mattress

GH's textiles experts and consumer testers got hands on with this unique mattress that features Purple's GelFlex Grid material, a grid-like elastic top layer that balances squishiness with firmness. The material is not only breathable but also provides spinal alignment. Plus, the mattress has exceptional motion isolation technology, making it ideal for couples (or for when the kiddos crawl into bed). Although it's one of the pricier Amazon mattresses, it's currently $140 off for Prime Day. The splurge may just be worth it if you want to feel like you are sleeping on air, as one GH tester says.

8-Inch Queen Mattress

This Amazon-exclusive mattress is currently 20% off for Prime Big Deal Days, allowing you to shop a memory foam model for under $400. With more than 5,000 ratings and an average of 4.5 out of 5 stars, the Nod 8-inch mattress provides spine support and pressure relief. We also appreciate that it's made with CertiPUR-US certified foams and GreenGuard certified materials.

Medium Firm Memory Foam Mattress

A 12-inch profile with thick layers of memory foam designed to be comfortable for all types of sleepers lent this mattress a 4.5-star rating on Amazon. All you have to do is add the mattress to your shopping cart, wait for the box to arrive at your doorstep, unbox and unroll. The manufacturer says you can sleep on the mattress immediately, but it could take up to or more than 72 hours for any odors from the packaging to dissipate. Get it for a whopping 39% off for Prime Big Deal Days.

6/8/10/12 inch Gel Memory Foam Mattress

The #1 best-selling mattress on Amazon is currently 33% off. Made from CertiPUR-US certified foams, its 10-inch height is made up of dense support foam, pressure-relieving gel memory foam and a knit cover that's removable and washable. And with more than 8,900 five-star ratings on Amazon, this top-selling bed is one of the best mattress deals ahead of Prime Big Deal Days.

Memory Foam Medium Mattress

While the mattress and adjustable bed option is not on sale for Prime Day 2023, you can still snag the gel-infused memory foam mattress on its own for a discounted price we appreciate (15% off). The mattress is compressed and packaged in a box for easy delivery and set-up. The mattress has a ventilated design for breathability while you sleep.

Cooling Gel Memory Foam Mattress

Two inches of gel memory foam on this cooling foam mattress will cradle your body as you comfortably fall asleep at night. The foam support core provides a medium-firm feel ideal for multiple sleep positions. We appreciate the 100-night sleep trial, which is always something to look out for when shopping for mattresses online, as you have the option to return the product if it isn't the right fit. Best of all, you can shop it for under $350 during Prime Big Deal Days.

Are mattress sales part of Prime Day?

They sure are! As you can gather from our roundup of the best Prime Big Deal Days mattress sales, you can purchase a mattress from brands like Tuft & Needle, Serta and more for up to 50% off, depending on the sale. Save upward of $400 on your dream mattress — and use that extra money to add one of our favorite Amazon sheet sets to your shopping cart.
