Abstract
A task chair has a buttocks portion, with a size sufficient only for the bottom of a person sitting on it, and a thigh support separate from it. The thigh support is displaceable to at least partway under the buttocks portion and can be pulled forward while under the buttocks portion. As a result, the length of the seat surface can be adjusted to the body size of a person using the stool. The guide for the displacement is curved. The front edge of the buttocks portion is formed by padding that tapers in wedge-like fashion. The front part of the cushion rests on the thigh support, and the rear part is retained by a bearing shell. The buttocks portion can be designed to be pivoted together with the backrest.
