It uses breathable open-cell foam and a four-way stretch cover to promote airflow, helping to keep you cool for all-night comfort in warm or mixed climates.
It's ideal for hot sleepers who want an airy, responsive feel without sacrificing support, and for those who prefer a surface that moves with them rather than a traditional innerspring. It may be less ideal for sleepers who want a very firm or very slow-responding feel.
Expect a responsive, springy feel from the Breathe Flex Foam and an airy top layer. The four-way stretch knit cover helps the foam perform with surface softness, and the setup is simply placing it on your bed foundation.
Keep the cover clean by following any care instructions for the knit fabric, and avoid placing it on damp surfaces to maintain the foam’s supportive feel and airflow.
The breathable, foam-based design supports everyday sleeping and lounging in bedrooms, guest rooms, or dense-sleep environments where airflow and quick recovery from movement are valued.
Experience a responsive, all-foam feel designed for comfort and airflow. The top layer features breathable open-cell foam for cool, all-night airflow, while Casper Breathe Flex Foam delivers a springy, supportive feel that helps minimize tossing and turning without compromising comfort.
The four-way stretch knit cover moves with you, enhancing the benefits of the foam layers while providing surface softness. Backed by a 10-year limited warranty, this mattress is built for durability and long-term support.
