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.

Including Cozy Earth sheets, Casper pillows, Tempur-Pedic toppers and more unbeatable deals you don’t want to hit snooze on during Prime Big Deal Days.
