For all the hot sleepers out there, this ten-inch thick Zinus mattress is made with triple-cooling performance memory foam. What does that mean, you ask?

If you're on a budget but are still craving that premium quality (AKA, all of us), Lucid's top-rated hybrid memory foam and innerspring mattress is one to eye. It's also infused with charcoal to potentially reduce odor that builds up over time.

This ultra-popular, surprisingly affordable mattress from Linenspa is an excellent buy this Prime Day. It has support from firm memory foam and innersprings, but reviewers note that it's still soft enough to feel inviting after a long day.

Contributor Cade Hiser reviewed Sealy's Cocoon Chill mattress for our Best Mattress-In-a-Box round-up and stated he'd “never slept better” on it. “With the Cocoon Chill Memory Foam mattress, I do not wake up in the middle of the night like I used to, tossing and turning,” Cade said. “I also stay sleeping at a comfortable temperature throughout the night.” So it's safe to say most any mattress from Sealy will provide you with an equally stellar night of sleep. While the Cocoon isn't on sale this Prime Big Deals Day, the brand's Sealy Posturepedic Plus 14" Euro Pillow Top Mattress is available for a generous 40% off. A medium-firm mattress, the Posturepedic Plus balances sublime comfort and optimal support with features like response pro HD encased coils, DuraFlex pro coil edge, Sealy's signature supportive air gel foam, and more.

Another mattress from AD staff-fave Casper, the Element is also relatively affordable—priced at a friend mid-range cost that's currently an extra 25% off. Like the Wave, the Element features Casper's signature AirScape technology for optimal breathability. It's especially ideal for anyone wanting ultra-plush and cooling memory foam.

The name really says it all—the Beautyrest Black hybrid LX-class mattress delivers exactly that with a whooping six-layer make up. It features BlackICE with plant-based cooling technology, the brand’s signature AirCool memory foam, HD memory foam, zoned T3 pocketed coil technology, and energy foam to create a medium-firm mattress that will give you cooling comfort and adaptive pressure relief. The fact that it's currently $300 off is really just icing on the cake.

Commerce editor Audrey Lee found Leesa’s Studio mattress ultra supportive, noting that it has a nice amount of give without being too soft, so it’s safe to say the brand’s other Sapira hybrid mattress would also be a winner. The Sapira offers five different layers of support. There’s the comfort layer—with a responsive, high airflow foam that keeps you from getting overheated—and the high-performance memory foam recovery layer for pressure relief. Then, the transition layer (fit for all sleep styles), followed by a responsive support layer made of over 1,000 pocket springs to provide durability and stability. And finally there’s the high density foam base layer.

For those looking to “vibe” out on a more plush bed, the Vibe Gel mattress features a 12 inch profile made up of two inches of cooling gel memory foam, three inches of support form, and two three-and-a-half inch base forms. This mattress has over 40,000 five-star reviews, including this glowing one from a satisfied user: “I'm nearing a year of owning this mattress and I'm absolutely thrilled with it. This is the most comfortable one I've ever owned. I tend to get headaches from muscle stiffness and other mattresses sank too much. I do not have this issue anymore. It's the perfect level of firm without being excessive.” Still not convinced? How about a 20% off deal that brings the price tag to under $300?

This Prime Day, we want to make sure we cover the market on offerings from all of our favorite brands and retailers—like Casper. We’ve waxed poetic about the Wave Hybrid Snow, the Element and the Nova–two different AD editors have tested and can attest to the plushness–though if you want something more firm then the Casper Snow might be for you. The Snow in particular features the brand’s signature “Snow Technology.” This means it has HeatDelete bands, phase change, and a CoolTouch cover that makes this a great mattress for hot sleepers.
