The folding table legs on the slide next to the sofa have never worked properly & have collapsed before so I decide to replace them. Amazon had several but the
AP Products 013-070 Adjustable Folding Table Leg seemed to be the same unit so I ordered a pair. Second picture shows it next to the nonfunctional leg.
On receipt, they seemed identical to the originals. There is a slightly less expensive model
AP Products 013-135 that may work as well & has a simpler mechanism but has a different appearance.
