ABSTRACT:
A combination chair for children which can be adjusted between a plurality of positions having two pairs of legs forming bifurcated rocker elements which in one position form legs for the chair, and in another, form rockers. The leg and rockers rotate in unison, with their relative positions maintained by intermeshing teeth of gears, until height selection locking pins, which form part of the height selection lever assembly within the gearbox assembly and are controlled by linkages, engage predetermined height selection or position holes in the legs, such that the leg and rocker elements are locked into high, intermediate, low or rocker positions.
