Is the Casper Cloud One good for side sleepers?

The medium-plush top cushions shoulders and hips, which suits many side sleepers. Heavier side sleepers may want more support than this soft foam gives.

How firm is the Cloud One?

Casper rates it medium plush, so it sits on the soft side of medium. It is not a firm mattress.

Does the Cloud One need a box spring?

No. It works on a slatted frame, platform bed or adjustable base. A solid, supportive foundation helps the foam last.

How long does the Cloud One take to expand?

Casper says the mattress expands within about 24 hours after unboxing. It may take a day or two to reach full height and feel.

What does the 10-year warranty cover?

The limited warranty covers manufacturing defects such as indentations beyond a set depth. Normal softening and comfort preference are not covered.

Is $779.99 a good price for the twin Cloud One?

It is the only new price listed, $779.99 at ProFit Mattress as of November 8, 2026, so there is no competing store price to beat. Compare it with other twin foam mattresses before deciding.
