Beneath the cooling layers, a high-density foam foundation provides stable support, while adaptive comfort layers contour to the body and help distribute weight more evenly across pressure-sensitive areas. Choose from firm, medium-firm, or plush comfort profiles to match your preferred balance of cushioning and support.
