Abstract
A swivel chair has a leg with a support at the upper end of its upright column and two shells which are articulately connected to each other and at least one of which is articulately connected directly to the support. The one shell carries a cushion and forms therewith the seat of the chair. The other shell is assembled of two sections which are pivotable relative to each other about a horizontal axis, one of which supports the lumbar region of the body of the occupant of the chair and the other of which serves as a shoulder support. The one section is articulately connected to the rear portion of the one shell by two hinges.
