Claims15
A method comprising:
- providing a base module having a plurality of base fasteners;
- coupling a lift module to the base module, the lift module having a plurality of keyed apertures configured to receive the plurality of base fasteners such that when the lift module is coupled to the base module, the plurality of keyed apertures are aligned and secured with the plurality of base fasteners to prevent a vertical axial movement of the lift module;
- and
- coupling a chair module to the lift module, the chair module having a fastening mechanism configured to releasably attach to the lift module;
- wherein the lift module further comprises a lift, and a plate having towers configured to rotatably secure a proximal end of the lift to the plate, the method further comprising:
- actuating the lift such that the lift module can be raised or lowered so as to facilitate comfort and ease of coupling the chair module to the lift module.

A method comprising:
- providing a lift module joined with a base module,
- the base module having a base plate and a plurality of base fasteners disposed on the base plate,
- the lift module having a plurality of keyed apertures configured to receive the plurality of base fasteners,
- wherein the lift module is joined with the base module such that the plurality of keyed apertures are aligned and secured with the plurality of base fasteners to prevent a vertical axial movement of the lift module with respect to the base module;
- and
- attaching a chair module to the lift module via a fastening assembly, wherein the fastening assembly includes the chair module having traverse rollers and the lift module having traverse rails configured to receive the traverse rollers.
