Product Details
The Casper Cloud One is an all-foam mattress engineered for a plusher, cloud-like feel without giving up the support and breathability Casper is known for. It pairs a soft, cradling surface with the brand's Casper Core+ technology, which uses shaped foam pillars in the base to deliver deeper compression and a gentle sleeping-in sensation. Casper rates the feel as medium-soft, making it especially well suited to side and combination sleepers who want pressure relief at the shoulders and hips.
Construction is built around three functional foam layers. A breathable, open-cell Breathe Flex Foam top layer promotes airflow to help draw heat away from the body. Beneath it, an Align Memory Foam layer contours to the natural curves of the body to relieve pressure and minimize motion transfer. The supportive Casper Core+ base provides the structural foundation, balancing the plush top layers with durable, long-lasting support.
- 11-inch all-foam, medium-soft feel
- Casper Core+ technology for added plushness and support
- Open-cell Breathe Flex Foam top layer for airflow and cooling
- 100-night risk-free trial and 10-year limited warranty
It is a strong fit for sleepers who prefer a softer, more conforming surface but still want a stable, breathable bed.
