Casper The One review

Casper The One is the brand's least expensive mattress and the priciest pick on this list, at $799 for a queen in a 30% Black Friday sale against a $1,149 comparison value. It uses three layers of foam, which Casper names Breathe Flex foam, Align+ memory foam and the Casper Core, under a Cozy Cover, with a responsive, medium-firm feel. Casper says The One is Consumer Reports' top-rated all-foam mattress of 2026, while noting that Consumer Reports does not endorse products. The practical advantage is retail access: Casper runs stores you can find by ZIP code, so you can lie on the bed before you buy. The terms are a 100-night risk-free trial, free shipping and returns, and a 10-year limited warranty, which are the same as Zinus and Lucid at less than half the price. That gap is why it ranks last for value-focused shoppers despite strong documented features.
