Abstract: The strap retainer assembly comprises an anchor and insert wherein in the anchor is permanently secured to the frame of the furniture. The anchor has an opening large enough to accept the insert, yet be positioned such that when the insert is pulled laterally, it is retained by the anchor. The insert comprises a strap having opposed ends; each end is looped and secured by a clip. The clip is the portion of the insert placed into the opening of the anchor hereinabove mentioned. On furniture, the frame is fitted with opposing anchors. The insert is heated resulting in a pliable strap. Each clip of the insert is placed in the opposing anchors. When the strap medium cools, it shrinks causing a taught horizontal fit, thus bridging the furniture frame. The number of inserts placed within the anchors on furniture is dependent upon the sizing (width) of the inserts and the overall length of the anchors.
