I was about ready to post my three piece sectional from Anthro on Craigslist because I couldn’t get the armless chair and corner chair to stop moving around. Every time someone sat down or got up, they’d move. My 10 lb dog was literally falling into the gaps between them and struggling to get out like he was Indiana Jones. Enter: these connectors. We flipped each piece over, I found a solid piece of wood that formed a square base on each piece, aligned each side of the connector, screwed each side in with a drill, then we flipped them over and pushed them together. They’ve stayed perfectly flush with zero sliding ever since!
