Support Specs

The Hyper-Elastic Polymer™ Purple is a pressure-releasing material. This material is organized in a grid formation, which creates walls that can support or fold, depending on how much pressure it receives. It's durable enough to last decades so you won't develop a body impression. And it buckles under specific pressure, which provides excellent motion isolation so you don't feel someone else move in the bed.

Casper signature all foam mattress designed with a responsive yet supportive medium-firm feel.

Fabric Specs

NEW SoftFlex Wave Knit: 29% Viscose, 67% Polyester, 4% Lycra (all +/- 5%). A custom, super-soft knit with tons of stretch so it can flex with both your movement and the Grid's. Its breathable material is also the perfect complement to the Grid's 1,800+ air channels.
