    • A support frame for use in a lift chair. In one embodiment, the support frame includes a base frame having longitudinally spaced transversely extending front and rear frame base rails; a first longitudinally extending side frame base rail connected to the front and rear frame base rails and a second longitudinally extending side frame base rail connected to the front and rear frame base rails, respectively, the first and second side frame base rails and the front and rear frame base rails being co-planar for supporting the lift chair on a surface; and a force balance member mounted to the rear frame base rail. The force balance member has a transversely extending base portion, a first arm portion extending from the base portion at a first angle αa, and an opposite, second arm portion extending from the base portion at a second angle αb.
