The Beautyrest BRS900-C Medium mattress is one of the mattresses in the C series that emphasize Support, Longevity, and Coolness. This mattress offers just enough softness in the sleeping surface over a Beautyrest Pocketed Coil® support. The coil enhances motion separation, conformability, individualized back support, and pressure relief. The Beautyrest Pocketed Coils® offer excellent motion separation when sleeping with a partner as well as enhanced conformability versus traditional wire tied coil systems. Enjoy elevated comfort with Dual Cool™ Plus Technology, enhanced with Silver designed to move both heat and moisture away from the surface of the mattress. Layers of AirCool foams, memory foams and GelTouch foams add to the comfort and support. The mattress perimeter is reinforced with Ventilated AirCool BeautyEdge® foam encasement. This offers a comfortable seating edge as well as an increase in usable sleeping surface and edge durability. This mattress has a medium firm feel that is going to appeal to most sleepers.
