ABSTRACT:
A bed having upper and lower bunks. In order to make it easy to "make" the bed the upper bunk can be moved sidewise and then tilted to give a person desiring to make the bed easy access to the upper bunk. The axis about which the upper bunk is tilted may be selected to enable the tilted bunk to be higher or lower as desired. The movement of the bunk is provided by cam surfaces on the frame of the bed and cam followers on the mattress trays of the upper bunk. One set of cam followers act as a pivot to enable the rotation of the upper bunk. Locks are provided to hold the mattress tray in either its normal position or its tilted position.
