Is the Casper One good for side sleepers?

Yes. The medium foam gives enough give at the shoulder and hip for most average-weight side sleepers. Heavier side sleepers may want a softer or thicker model.

Does the Casper One need a box spring?

No. It works on a slatted frame, platform bed or adjustable base. A solid or slatted foundation with good airflow is best; avoid a sagging old box spring.

How does it compare with the Casper Original Hybrid?

The One is all foam with fewer layers and no coils. The hybrid adds springs for more bounce and better edge support, at a higher price.

Is the Casper One good for couples?

Yes. The foam absorbs motion, so one partner moving disturbs the other less. It sleeps warmer than a hybrid, which matters if either of you runs hot.

What sizes does the Casper One come in?

It comes in the standard sizes from twin through California king, all at 11 inches tall and medium firmness.

About the Casper One 11" Medium Mattress CA King

The Casper One is Casper's streamlined all-foam mattress, sold in one firmness (medium) and one height (11 inches). It uses a breathable polyurethane foam top layer over a support core, with a knit cover and handles on the sides. It suits side and back sleepers of average weight who want a simple, well-known foam bed without a premium price tag. Compared with Casper's multi-layer hybrids, it has fewer layers and no coils, so it isolates motion well but feels less springy and sleeps warmer than a hybrid.
