Abstract
A collapsible bed has a head frame and a foot frame that are of shaped metal tube. At each end of each frame there is a "U"-shaped recess. Two bars extend between the frames. At each end of each bar there is a disc with a peripheral channel. The discs seat in the recesses and lock therein. A sheet of material extends between the bars, the bars passing through casings on opposed sides of the sheet. The inner sides of the recesses of each frame slope towards one another to assist in guiding the discs into the recesses and to stretch the sheet of material.
