The Serta High Profile 9-Inch Box Foundation is a fabric-covered support base for a compatible mattress. It adds 9 inches beneath the mattress for a taller bed. Overall bed height also depends on the mattress and the frame.
It has a wood support structure with a fabric cover. Reinforced edges and center support help spread the mattress load across the foundation. It is American-made and arrives fully assembled.
This is a stationary foundation, not a powered adjustable base. It is meant to sit on an appropriate bed frame. Match it to the mattress size, the bed frame and the mattress manufacturer's support requirements. A King setup uses two matching Twin XL foundations, so confirm the set contents for the King option.
