A collapsible bed frame () for supporting a mattress, the collapsible frame () having a number of frame members (). A number of pivots () connect pairs of the frame members () at the midpoints of the frame members () to make a number of scissor pairs ().

The upper connector assemblies () form a support surface for a mattress.
