A mobile support assembly disposable between a stored orientation and an operative orientation including a frame having a front leg assembly including a pair of front legs, and a rear leg assembly including a pair of rear legs. At least one but preferably each of the front and rear leg assemblies include at least one cross member spanning the corresponding legs thereof. Each cross member is structured to have a variable length so as to effectively vary an overall width of the mobile support assembly and thereby facilitate a compact configuration of the frame when in the stored orientation. Further, at least one of the leg assemblies includes a lower portion wherein the wheels are included, the lower portion disposable into a non-operative storage position that at least partially defines a reduced longitudinal dimension of the frame when in the stored orientation.
