## Overview
Casper believes that buying a mattress should be as easy as sleeping on it. That’s why they created the Casper One Mattress, designed to be the no-brainer mattress choice. Engineered with breathable and pressure-relieving foams to soothe you to sleep and cradle your body all night long, it has everything you need—and nothing you don’t. Inspired by our very first mattress and perfected with ten years of real feedback, better sleep starts with One. All Casper mattresses are designed and assembled in the USA and include a 10 year warranty, so you can rest assured.
- Consumer Reports named The One the top-rated all-foam mattress of 2026.\*
- Features a top layer of Breathe Flex Foam that’s both responsive and breathable to soothe you to sleep with the perfect bit of bounce.
- Feel deep pressure relief with Align Memory Foam that cradles your body to help you stay asleep.
- A firm Casper Core base provides long-lasting support while preventing sinking and sagging.
