ABSTRACT:
A removable tray for a walker including a walker having a pair of spaced upper side bars. Further provided are a pair of walker coupling mechanisms adapted to be coupled to an associated side bar of the walker via clamps. A tray is slidably coupled to the walker coupling mechanism such that only lateral relative movement is allowed prior to use. Finally, at least one flexible strip is coupled at a first end thereof to the tray for coupling about at least one of the side bars of the walker to preclude lateral movement of the tray during use.
