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.
