The Resort II Ultra Firm is perfect for sleepers wanting body-conforming firmness with increased support, temperature regulation and motion reduction. Experience undisturbed sleep with our pocketed spring system which provides advanced support while limiting the movement of the bed from your sleep partner. To reduce the exchange of motion even further, the Gel-infused foam comfort layer conforms to your shape to relieve pressure at sensitive areas of the body. CoolTex Copper fabric helps cool the surface of the mattress to keep the sleeper comfortable as it pulls heat away from your body. You will also enjoy the Quantum Edge system which maximizes the sleeping surface with a firmer coil on the sides of the mattress allowing you to sleep right to the edge of your bed. And because the mattress is compatible, sleepers can pair it with an adjustable base to find the perfect sleeping position.
