摘要

A chair has a chair column on which a front seat support member is fixed. A rear seat support member provided with a back-rest support for a back-rest is joined to the front seat support member by a pivot axle. A seat is supported on the two seat support members. The seat is supported in relation to the rear seat support member by a supporting axle, which is adjustable in height relative to the rear seat support member by a seat pitch adjuster. The seat pitch adjuster can be a retrofit kit.
