Abstract
An office chair or office chair element, such as a backrest or seat, has a flat covering element, such as a fabric, cushioning or webbing element, secured to support elements, such as the arms of a support frame, and tensioned in between. The covering element is provided with a welt strip that, in the fitted state, is placed in an accommodating groove in the support element. The accommodating groove has two oppositely situated contact faces for the welt strip and one of the contact faces is provided with a projection that projects into the accommodating groove and extends in the longitudinal direction of the groove. The welt strip can be pressed into the accommodating groove, resiliently deforming the projection and/or the welt strip and the welt strip, in the fitted state, is positively locked and/or friction-locked in the groove with abutment against the contact faces, with the projection preventing the welt strip from escaping from the accommodating groove.
