As you may have noticed, mattress shopping holidays aren’t limited to just Memorial Day, Labor Day, or even the Fourth of July anymore. Now that Amazon Prime Day is nearly a week long, it’s become something of a holiday in and of itself, so it makes sense that mattresses (plus other bedding!) will be on sale too, both on Amazon and beyond.
We’ve listed our favorite Prime Day mattress deals that someone on our staff has tested themselves and personally vouched for. If you want to know more about our favorite mattresses, we have you covered there too. Keep an eye on all the Prime Day sales going on, as we are doing lots of live coverage to keep you informed. And of course, we’ll keep this list updated as deals roll in.

Updated 1 pm ET July 10, 2025: We’ve updated deal prices in this story, and added deals from Helix, Birch, Coop, Slumber Cloud, and Cozy Earth.

DreamCloud
Hybrid Mattress
When WIRED Reviewer Molly Higgins tested the DreamCloud Hybrid, there were some standout (or, rather, bounce house) features to the bed. Given the hybrid construction, the memory foams and coils weren’t just supportive—they were very responsive. This kind of bouncy feel could be helpful for co-sleepers and combination sleepers who toss and turn a lot in their sleep. Molly also noted that while the bed’s edge support was an actual letdown (meaning not the most sturdy), the policies definitely weren’t. The DreamCloud Hybrid has free shipping, a yearlong sleep trial, and “forever warranty” coverage against defects. Plus, now it’s on sale! Woo-hoo!
Fresh With Green Tea

Zinus
Green Tea Memory Foam Mattress (12-Inch)
I know matcha lovers everywhere just perked up, and yes, the Zinus 12-inch green tea memory foam mattress does indeed contain green tea. The premise of this all-foam mattress is the use of green tea and charcoal infused in its memory foam layers to keep out moisture that could result in germ and odor buildup. WIRED reviewer Molly Higgins also gave this bed a go and found it to be a bit too firm for her smaller stature. However, this exact reason could be beneficial for sleepers with back pain, as well as heavier sleepers, who require a firmer surface to keep their spines happy and in alignment.
For a Straight Spine

Some people swear by the power of the Plank, and two of those people happen to be testers on WIRED’s team. Reviewers Adrienne So and Nena Farrell have both spent time with this flippable, super-firm bed. Both find that it is the firm feel that plays a crucial role in maintaining spine support and keeping it from slipping and dipping into odd angles. The king-size version of the Plank Firm is on Prime Day special.

Coop Sleep Goods
Original Adjustable Cutout Pillow
After testing nearly 30 different pillows, our testers still can’t stop raving about Coop’s pillows. Our resident side sleeper pillow tester, Nena Farrell, says she always comes back to Coop’s cut-out pillow when she isn’t testing something new, and she’s gotten this pillow for both of her parents. Score one for yourself on sale!
Affordable and Amazing

What was once an impulse purchase has turned out to be one of the best sleep-related purchases I’ve made to date. These cooling bamboo sheets feel just as buttery and luxurious as some pricier brands out there that I’ve tried. Plus, they’re on sale for Prime Day—the hard part will just be picking out what colorway you want.

Slumber Cloud
Performance Tencel Sheet Set
Lots of sheets will claim they’re cooling, but WIRED reviewer Nena Farrell has found that if there isn’t good breathability, no promise of phase change material technology will keep you cool. Slumber Cloud’s Tencel sheets are one of the only sets she likes with both PCM technology and a breathable (yet super soft!) design that will actually keep you cool all night long.

Cozy Earth
Bamboo Sheet Set
Cozy Earth’s bamboo sheets are some of the softest bedding you’ll ever try. These bamboo sheets are chilly and silky, but still have a cozy feel to them that you won’t find in other sheets. They’re a splurge, but right now you can use the code WIRED to get them for over $100 off.
A Pillowcase for Hair Health

I see this thing all over TikTok, and I already know that silk has a lot of benefits for skin and hair health. If it’s the same targeted ads for you, now’s the time to find out for yourself if it’s the pillowcase of your dreams. As for WIRED reviewer Louryn Strampe, she mentions that the silk’s soft slipperiness (say that three times fast) is awesome, and the zipper keeps it from sliding right off her pillow.
