Airscape™ 3 with cooling gel: 3 layers of perforated breathable foam help keep you cool. Air channels allow heat to escape to prevent overheating. Added cooling gel feels refreshing throughout the night.
Idle Cooling Buoyancy Foam is made without visco elastic chemicals so Idle stays cooler than memory foam with better pressure relief. Perforated holes in the transition layer foram that help the mattress breath and provide extra responsiveness.
Premium foam feels cozy and conforms to your body to relieve pressure. Supportive memory foam has 3 ergonomic zones to help align your spine and provide more relief. Gel pods under the waist and lower back add support and help keep your spine perfectly aligned in any position. Zoned Support™ Max provides full-body relief and ease aches and pains. A firmer border provides edge support to help you get in and out of bed easily. The most advanced support system designed for less aches and pains. Zoned Support™ Max: Continuous ergonomic zones for full-body relief. Softer foam around the shoulders provides more relief to the upper body. Healthy spinal alignment for all sleeping positions.
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. Three inches of our custom blended foam with gel infusion, reacts faster than memory foam and has better support for more pressure relief, all while sleeping cooler. At 7 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.
