The best extended Prime Day mattress deals can help you upgrade your bed for less. We've rounded up mattress deals you can still shop now.

Pillows, sheet sets, sleep masks, and more Wirecutter-approved sleep gear that’s on sale for Amazon’s Prime Big Deal Days.

While the sale has officially ended, there's still one amazing deal you can grab right now. We don't know how long it will last, so we recommend acting quickly. My top pick is the Tempur-Pedic Tempur-Adapt + Cooling Mattress Topper up to 50% off at Amazon, with a queen-size going for $251 (reg. $499).

Bear, the maker of our favorite side sleeper mattress, is also running a sale during Prime Day. It's got 35 percent off sitewide with the code PRIME, plus two free pillows with any mattress purchase. It brings the mattress to the price we usually see it available for, though the $150 worth of pillows makes it a bit of a discount.

The bed-in-a-box memory foam mattress is made of five layers that include a heat-wicking quilted cover with cooling technology, perfect for hot sleepers who often deal with night sweats. Once delivered to your door, it's super easy to set up, too. Just take it out of the box, lie it on top of your frame, and let it expand for 24 hours.

The Prime Big Deal Days event is on October 8 and 9, and it includes mattress deals from Casper, Purple and Nectar, with up to 31 percent off.

The day we’ve all been waiting for has finally arrived. That’s right, Amazon’s Prime Big Deal Days are officially upon us. It’s like Black Friday came early, minus the need to camp outside a store or wrestle someone for the last discounted toaster.

These are the top mattress deals during Amazon Prime Day, including major savings from Nectar, Tuft & Needle, Sealy, Serta, and more.
