Nectar gives you the support of a firm mattress while pampering you with the comfort of a pillow top. The five layers of foam combine to provide the ultimate sleep surface. The top layer of quilted memory foam stimulates air flow beneath your body, while the Tencel cooling cover wicks away unwanted heat and moisture so you sleep cool and comfortable. A gel memory foam layer distributes weight evenly and offers cool, contouring support while the adaptive Hi Core memory foam and breathable base layer provide reinforced support and crucial rebound and bounce.
