Our take on the Casper One Foam Mattress

The Casper One is Casper's all-foam mattress, built with memory foam in a medium-firm feel and a soft knit cover that zips off for washing. It is fiberglass-free, CertiPUR-US certified and made in the USA, and it is aimed at back and stomach sleepers who want a simple foam bed. The only new price listed is $749 at The Home of Foam Mattress Superstore as of November 4, 2026, with no other new-price data to compare against.

Cons

Questions and answers

Is the Casper One good for side sleepers?
Casper lists it for back and stomach sleepers, and the medium-firm foam may feel too firm for some side sleepers. Side sleepers usually want a softer top layer at the shoulder and hip.
Does the Casper One come with a foundation or base?
No. The mattress ships without a foundation, and Casper lists adjustable bases as compatible. Budget for a base or frame separately.
Does the Casper One contain fiberglass?
No. Casper states the One is fiberglass-free, which matters if you are avoiding fiberglass in mattress covers.
Can I wash the cover?
Yes. The soft knit cover is removable and has a zipper. Follow the care instructions on the label rather than machine washing on a guess.
Is $749 a good price for the Casper One?
It is the only new price listed, $749 at The Home of Foam Mattress Superstore as of November 4, 2026, so there is no second new price to compare it with. Check the size that price covers before judging the deal.
Is the Casper One safe for kids?
Casper does not list it for kids. The listing says "For Kids: No," so look at a mattress explicitly rated for children if that is the use.

At The Home of Foam Mattress Superstore, for $749.00, 30% off, as of our latest check.
