Abstract

Abstract An infant chair is comprised of upper and lower resilient wire frames with the lower frame having a horizontal ground-engaging base with opposite side members diverging forwardly from a common crosspiece. The forward portions of the side members incline upwardly and rearwardly for connection to the upper frame. The upper frame has back, seat and leg support portions and releasable connectors interconnect the inclined side member upper ends to the back, seat and leg supports of the upper frame. The back, seat and leg support portions are encased by a removable, flexible covering.
