A good night�s sleep starts with a firm foundation \n A solid foundation is the basis of everything. Our Sealy Posturpedic Queen Foundation isn't just a box spring. This firm foundation was specifically designed to create an environment where your back can get the support it needs, by being slightly firmer than most. \n Featuring a rubberized fabric specific to Sealy�s Stay Tight� technology, the Posturpedic Queen Foundation will hold your mattress in place and help keep your sheets in order, night after night while you rest and recoup from the day. \n If you still want the quality Sealy brings to a foundation, in a smaller size, have a look at our Sealy Full Foundation Standard .
