The present invention relates to an arrangement in a chair, especially for regulating the level of the seat, etc., comprising a rack or carrier frame (3) extending upwardly from a base (2), on which carrier frame for example a seat member (4) is removably attached, by detachable holding means (6a, 6b) for in detached position allowing sliding along said frame (3) for affixing at various levels, and for the purpose of providing an arrangement involving both simplified regulation of chair member level, as well as variation in the appearance of the chair, its field of use and mobility; it is according to the invention suggested that said carrier frame or carrier rack (3; 103; 203; 403) comprises at least one pair or set of substantially parallel elongated means (3a, 3b; 103a, 103b; 203a, 203b, 203c; 303a, 303b; 403a, 403b) having at least an intermediate slot (5; 105; 205a, 205b; 305; 405), and that in the area of said slot there are provided chair member carrying holding means (6a, 6b; 106a, 106b; 206; 306a, 306b; 406a, 406b), which holding means comprise friction elements (7x, 7y, 7z; 107x, 107y, 107z; 207w, 207x, 207y, 207z) which in a first chair member carrying position (Fig. 3) will induce a locking effect against the rod-shaped means, and which in a second released position of said chair member carrying means (Fig. 4) will be released from its locking effect against said elongated means for thereby allowing a displacement of said chair member carrying means to various level positions.
