The revolutionary X-Brace system center support system is designed to be easily installed and help support your Full, Queen, King, or California King sized bed. Using the included legs, you can assemble this support system to adjust from heights as low as 6 inches, all the way up to 15-1/2 inches in height (measured from the floor to where the bottom of the box spring rests.) This unique center support system provides superior coverage under your bed to evenly support the box spring and mattress. The revolutionary X-System design creates a special synergy which adds an extra dimension of support to protect your bed and bedding, so you can protect your bedding investment and ensure a great night sleep.   The legs of this support are easily adjustable to allow a wide range of height, accommodating almost any bed configuration. The support system also adjusts in width to fit Full, Queen, King, and California King sized beds. Designed for strong support of your bed. 3 sturdy metal rails and 3 feet hold your mattress in place. Replaces wooden bed slats. No more sagging mattress! The Positive-Locking leg design actually gets stronger when you apply the weight of the bed, with super strength to give you peace of mind. Since the three cross rails are all connected, this support stays in place over time. There are no complicated instructions to follow when installing this center support (although there are instructions in the box, just in case.) Using the unique "Gripper" Super Clamp, which comes preassembled, you can easily adjust the center support to the size of your bed  and attach the pieces together to create a heavy-duty support system. The cross slats of this system have pre-drilled holes in the ends where they overlap your side rails, and are easily secured to the bed using the included screws. This ensures your center support system will not move around, and also protects your side rails from bowing or bending.
