ABSTRACT:
A stackable wheeled chair particularly for use in a mobile blood collection system. Each chair comprises a pair of laterally spaced, generally inverted U-shaped leg means. Each leg means includes front and rear leg members which diverge downwardly from an upper connecting member with flared offset portion at the lower end of each of each leg member rotatably supporting a caster means. Each leg means includes a stacking member spanning its front and rear leg members and positioned below the connecting member. The stacking members includes portions resting on the connecting member of the next lower chair in a stack with side portions to preclude lateral tipping. The wheels of the caster members ride on the flared portion of the next lower chair in a stack to preclude front-to-back tipping. Substantially no other contact exists between the stacked chairs to preclude wedging.
