A bed frame system for use particularly in hotels that includes side rails and cross rails that include extruded plastic panels that extend downwardly to the floor to block the space underneath the bed frame. The cross rails are connected to the side rails by corner members with a system that allows the entire bed frame to be assembled without the use of tools. In one embodiment, the bed frame is a platform style bed frame that is constructed of an upper bed frame section and a lower bed frame section that are interlocked together to raise the height of the bed frame and eliminate the foundation. The bed frame may have a deck made up of a plurality of individual slats that are supported by the side rails to support the mattress.
