Frame for pivoting folding furniture having varying counterbalancing torque values

A folding bed apparatus for selectively and alternatively moving a bed from a substantially vertical storage position to a substantially horizontal usable position, comprising:

• a support assembly for housing said bed when in said storage position;
• a bed frame for supporting a mattress and collectively defining said bed, said bed frame being pivotally connected about a pivot axis to said support assembly;
• at least one lower mounting bracket mounted to said bed frame near said pivot axis and at least one upper mounting bracket mounted to said support assembly, said lower bracket having a plurality of first mounting points and said upper bracket having an associated plurality of second mounting points;
• at least one counterbalancing piston for creating a torque acting on said bed frame toward said storage position, said counterbalancing piston being pivotally and removably connected at one end at a selected one of said mounting points on said lower mounting bracket and pivotally and removably connected at the other end at a mounting point of said upper bracket associated with said selected mounting point, thereby allowing said counterbalancing piston to be repositioned between said first mounting points and said associated second mounting points to vary the counterbalancing torque acting on said bed frame.
