Edge-to-edge coils provide stable perimeter support, making it easier to sit, sleep, and get in and out of bed without feeling like you might roll off. Motion control helps isolate partner movement so you are less likely to wake up when they turn or get up. Ideal for side sleepers and combination sleepers, this model is perfect for anyone who overheats easily but still wants a luxurious, contouring, ultra plush mattress that feels cool, calm, and incredibly balanced all night long.
