ABSTRACT:
A chair includes a base, a seat unit with aplastic casing, and a seat supporting unit, which is fixed on the base to support the seat unit thereon. The casing includes an upper plate and a lower plate, which are coupled together along outer peripheries thereof. The seat supporting unit includes a horizontal seat supporting plate, which is fixed thereon. An elongated metal auxiliary supporting member is fixed on the seat supporting plate, and has a left end portion that extends from a left side of the seat supporting plate, and a right end portion that extends from a right side of the seat supporting plate. Accordingly, the casing is supported on the seat supporting plate and the auxiliary supporting member. Preferably, the upper plate is formed integrally with a plurality of hollow posts, which are bolted to the seat supporting plate, thereby fixing the lower plate and the auxiliary supporting member between the upper plate and the seat supporting plate. As such, left and right tilting of the seat unit can be prevented by the auxiliary supporting member.
