Casper One Mattress

The Casper One is specifically engineered for back and stomach sleepers who require a firmer surface to maintain proper spinal alignment. Side sleepers typically need more contouring and give at the shoulders and hips, so this mattress may feel too firm for that position.

This mattress features built-in temperature regulation designed to dissipate heat throughout the night. While it is not a specialized cooling mattress, it is engineered to prevent the heat buildup often associated with traditional memory foam.

The 11-inch profile provides a substantial, durable base that prevents the 'sinking' feeling often found in thinner foam beds. It offers a firm, responsive feel that keeps you supported on top of the mattress rather than feeling trapped inside it.

The Casper One is compatible with most solid, flat surfaces, including platform beds, slatted frames, and adjustable bases. If using a slatted frame, ensure the slats are spaced no more than 4 inches apart to prevent the foam from sagging.

The Casper One is categorized as firm. It is designed to provide a balance of comfort and resistance, making it ideal for those who prefer a stable, supportive sleep surface over a soft or plush one.
