We've extensively tested top-rated mattresses and tracked price histories to find the best Prime Day mattress deals to shop during Amazon Prime Day 2025. But hurry—Prime Day ends tonight.

We’re into the final hours of the four-day Amazon Prime Day 2025 sale. So, if you need to upgrade your worn-out mattress, now’s your last chance to do it for less, as I’ve found the best mattress deals in the summer sale event.

What we like: Our pick for a cloud-like yet supportive hybrid mattress should appeal to back sleepers and stomach sleepers, as well as to side sleepers who prefer a firmer mattress. A crowd favorite in our most recent panel test, garnering the most positive feedback among the nine mattresses we tried. Good edge support.
