Our premium stretch-knit cover is infused with a proprietary "Phase Change Material" that absorbs and dissipates heat for a refreshing, cool to the touch surface.
A unique replaceable cover with gel sewn into the quilted surface, and wraps our Idle buoyancy foam. You can literally feel the freshness when you touch it. Its also made of 500GSM pure cotton, which is why its able to provide such a luxurious feel. A washable, durable and replaceable base cover to keep your mattress clean. Just unzip at the side and its ready to be removed for cleaning.
A top layer of memory foam helps reduce the amount of movement from your sleep partner. The Soft model reduces a bit more motion transfer than the Firm model. Phase Change Material (PCM) absorbs your body heat leaving you with a cool to the touch mattress experience.
Idle Cooling Buoyancy Foam is made without visco elastic chemicals so Idle stays cooler than memory foam with better pressure relief. Unlike normal memory foam that doesn't provide much support to where you need it most, our custom foam has greater thermal neutrality which means it goes back into shape much quicker and retains less heat.
Our high-quality memory foam adapts to your body size, shape and sleep position to ensure a great sleep no matter which feel is right for you. Support Foam base layer engineered to be highly durable and resilient. We've tested it, and we know it bounces back every time.
Rapid Response Technology. Idle foam mattresses benefit from advanced thermal neutrality, guaranteeing your body a comfortable contoured support which rapidly returns to form when you move, meaning no more sink holes across your mattress. Little to no motion transfer. Two layers of our custom blended Buoyancy foam with gel infusion, reacts faster than memory foam and has better support for more pressure relief, all while sleeping cooler. At 8 inches, our bases provide superior stability for every layer. Its one reason our Idle foam gel mattresses have at least 1" extra height compared to other brands. At 2.4lb of foam core density, this is at least 30% more than the market average, making it extra durable.
