Casper Nova Hybrid vs Purple Premier 4 - 2025 Review

The Purple Grid™ has thousands of open air channels that feel cool as you lie doown and neutralize your body heat throughout the night so you sleep comfortably all night long. Air circulates more easily through the interior coils, which perfectly complement the Grid's built-in air channels and temperature-neutral gel material.

When it comes to our signature Purple Grid™, the thicker the gel grid, the less pressure you'll feel. The hyper-elastic polymer gel Grid immediately flexes to support your position and springs back into place as you readjust or move. The Purple Grid™ is designed to dynamically flex under pressure so it cradles pressure points like your hips and shoulders while still supporting the rest of your body. A border using high density foam creates reinforced edge support. Responsive Support Coils. Individually wrapped stainless steel coils pair with the Grid™ to offer dynamic pressure relief and support. Each coil is wrapped in responsibly sourced premium noise-reducing fabric. The Purple Grid™ is a flexible gel material that instantly adapts to your body and sleep position, providing soft support where you want it and firm support where you need it. 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.
