Abstract
Abstract A stackable chair kneeler having a padded horizontal portion mounted on a kneeler frame which is pivotally attached to a Ushaped subframe and swingable between a down position wherein the padded portion may be knelt upon and a retracted position wherein it is held by detents in coplanar alignment with the U-shaped subframe. The U-shaped subframe in turn is swingable between an operative position in coplanar alignment with the rear legs of the chair and a storage position lying just underneath the seat, with the subframe being selectively held in said operative and storage positions by spring loaded retractable studs or detents engageable in suitable holes drilled in the frame of the chair.
