The Casper Select mattress features four layers of premium foam for the perfect balance of softness and support. The Zoned Support™ system treats your shoulders and hips differently for deeper comfort and better alignment. Just the right sink, just the right bounce. Two technologies come together for better nights and brighter days. Our mattress is made with premium foam for cooling and bounce - ensuring breathability and durability for years to come. Each of the four layers provides unparalleled support and comfort. Our bed is resilient enough to compress-ship and fit through any door! The Casper Select brings better sleep, all in a magically compact box.
