What sets it apart
Three foam layers provide a coil-free mattress with a published medium-firm feel.
Our take
The One is the simpler Casper option for a foam-focused budget. Compare Cloud One if you want a more plush-oriented take on that concept.
Reasons to consider it
A coil-free design is worth comparing if you prefer a quieter, less spring-driven response.
The tradeoff
A foam comfort stack may feel more enclosing and make position changes less effortless than a responsive spring or latex build.
These comfort observations are editorial inferences from construction and published firmness, not results of hands-on testing.
Price and configurations
The recorded queen price is $899. This is a dated mattress-only offer, not a live checkout quote.
For context, the Cloud One starts at $1,099 in this catalog, $200 more than The One. Compare the construction and firmness below before treating the difference as an upgrade.
Price snapshot: September 10, 2026. USD, before tax. Delivery, accessories, bases and later promotions can change your total.
Trial, returns and setup
Confirm the current home trial directly with the seller. Check the required adjustment period, pickup or return fees, condition rules, eligible foundations and warranty exclusions. A retailer purchase may have different terms.
