Element Mattress

$645.00

Casper

The Element mattress provides an introduction to Casper comfort, combining a balance of both softness and support. The innovative cooling system is designed to keep you cool all night with a top layer of perforated breathable foam to reduce heat and tiny holes move hot air and body heat away. A layer of memory foam conforms to your body to relieve pressure and the durable base foam prevents sinking while providing full-body support.Size:Queen.
