The loveseat looks like the glider my parents had we were kids. The issue I have this the worse item I have ever put together. Use photos with the directions. The wrench supplied did not fit the nuts. When the back and bench are assembled. They will bend back way past where they should. You Abe stick a bolt through the side panel got a stop put with will scratch the backside. I used a 14 rod 39 inch’s long similar to the two  cross bracing rods see photo. I put the rod through 38 cleat tube. I think black or shrink tubing might be better. Than nut at each end . Do not attempt assembly your self and have a pair of Tweezers￼ for the glider nylon washer or something sticky to hold them. Elmer white glue stick. Also I would consider assembly not on the ground. Whoever wrote the directions mush be having a good ￼ laugh. ￼
