Abstract: A rugged rolling high chair for commercial duty, as in restaurants and cafeterias, in which preformed rigid tubular members are interconnected relative to a one piece molded seat member to obtain a stable assembly. An upper frame member is in the form of a closed loop having a front part, spaced side parts, and a forwardly tilting rear part, the rear part supportingly contacting the backrest of the molded seat and the side parts supportingly contacting the sides of the seat. Each of a unitary pair of leg members have front and rear legs connected by a top transverse portion which also supportingly contacts the sides of the molded seat. A cross brace spans aligned front legs of the unitary leg member and supportingly contacts the bottom of the one piece molded seat. A rigid crotch bar is joined to the cross brace and the front part of the upper frame member.
