A cross-rail support system for use with a bed frame to support a mattress having at least two adjustable support leg assemblies attached to two parallel and adjacent elongate beams. The overall width of the support system is adjustable by sliding the elongate beams relative to each other along their lengths. The placement of the two support leg assemblies is also adjustable by sliding the assemblies along the elongate beams and is independent from the total width of the support system. In addition, the leg assemblies maintain the parallel alignment of the elongate beams to each other and provide support to the mattress. The leg assemblies include telescopic extensions that have locking means, and at least one open ended groove that accommodates a locking means.

This application is a divisional of U.S. application Ser. No. 11/069,603, filed Mar. 1, 2005, now U.S. Pat. No. 7,134,154, which is hereby incorporated herein in its entirety by reference.
A clamp assembly for securing a pair of overlapping cross support members extending between two opposed side rails of a bed frame is provided. The clamp assembly includes a unitary clamp body, a leg assembly pivotally secured to the clamp body and a locking plate pivotally secured to the clamp body. In order to prevent the cross support members from sliding relative to one another, the leg assembly exerts force on the overlapping cross support members. The leg assembly may comprise a first leg pivotally secured to the clamp body, a plastic insert and a foot member. Alternatively, the leg assembly may comprise a first leg nestably secured to a second leg in order to increase the length of the leg assembly.
