Wheelchair access system

A system for facilitating access, includes, a tabletop having an undersurface; a tray support movably positioned relative to the undersurface of the tabletop so as to be positionable between a retracted position in which the tray support is inward of the undersurface of the tabletop and an extended position in which a portion of the tray support extends outwardly from the underside surface of the table top; a tray having an upper tray surface; a height extender removably couplable to the tray; and a lock. The lock is operatively associated with the height extender and the tray support, and is configured to position and lock the tray to the tray support when the tray support is in the extended position, and to locate an upper planar tray surface of the tray at a desired height relative to the tabletop.
