    Abstract: A combination of a reinforcing grommet in a D-shape or a closed horseshoe shape and a supporting brace for holding a tensioned surface on an inclined frame element of a frame of a collapsible furniture item, such as a chair, a stool, lounger, table, a cot or a bed. A contact portion of a lower surface of the grommet rests on a brace and a remaining portion of the lower surface spans a recess in the brace. The brace is freely movable to and fro relative to the frame tube so as to minimize tearing forces.
