We also have the party couch, but have a 2014 Sandpiper 376BHOK. The two pedestal tables gave us the same problem, so we aren't even using them. They were entirely too wobbly and leaned as you say toward the couch. If you stepped past them to sit on the couch, they would lean even more until you sat down. We bought a table from Target that came with 2 chairs. The top on it folds so the table is narrow, but can be opened to about the size of a card table if needed. There is also storage under the table top. It matches well and we like it much better. We bought a rectangular ottoman to sit in front of the other end of the party couch, as the table only takes up half the couch. It works very well. The link to the table we bought is at the end of my comment. I hope this helps. To be honest, the pedestal tables are the only thing we didn't like about our camper and it's something Forest River needs to improve the design on. Other than that, we love our camper so much.
