Patent ID: 7134154

Claim:
A cross-rail support system for use with a bed frame to support a mattress, the cross-rail support system comprising: a pair of elongate beams in parallel alignment, each having an inner end and an outer end and together defining an overall width between the outer ends that extends across the bed frame; and at least two leg assemblies for maintaining the parallel alignment between the beams and providing support to the mattress, each leg assembly including, an elongate tube that defines at least one interior space for holding the elongate beams, wherein the elongate beams are slideable relative to each other thereby adjusting the overall width of the cross-rail support system, and a leg structure depending from the elongate tube and having a height that extends generally perpendicular to the elongate beams, wherein the leg assemblies are slideable along at least one of the elongate beams and independently from the overall width of the elongate beams together so that the positions of the leg assemblies and the overall width of the cross-rail support system are independently adjustable; and wherein at least one of the leg assemblies is slidable past the inner end of at least one of the elongate beams.
