A collapsible bed frame ( 18 ) for supporting a mattress, the collapsible frame ( 18 ) having a number of frame members ( 32 ). A number of pivots ( 34 ) connect pairs of the frame members ( 32 ) at the midpoints of the frame members ( 32 ) to make a number of scissor pairs ( 35 ). Pivot assemblies ( 36 ) pivotally attach the upper ends of the frame members ( 32 ) to upper connector assemblies ( 40 ), and pivotally attach lower ends of the frame members ( 32 ) to feet ( 38 ), thus connecting the scissor pairs ( 35 ) to form an extended scissors-frame assembly ( 33 ). The upper connector assemblies ( 40 ) form a support surface for a mattress.
