An ideal blend of cooling and support, the Casper Hybrid mattress combines award-winning design and precise contouring for the sleep of your dreams. A top layer of AirScape perforated breathable foam increases airflow and reduces heat throughout the night. For all-night comfort, Casper's trademarked Zoned Support uses three areas of support beneath your shoulders, hips and lower back to align your spine. This hybrid model includes resilient springs that gently lift your body while reinforcing proper support. To make getting in and out of bed easier, a firmer border provides edge support. An eco-friendly cover made with recycled materials offers cozy comfort. Designed for all body types, this mattress offers the support you need whether you sleep on your back, side or stomach. 10 Year Limited Warranty
