The swing is heavy duty, not too difficult to assemble but the swing hangs closer to the left side legs (left side if you're sitting on it) and no matter what we did, even switching the springs, it won't hang in the center of the legs.  We checked and double checked the labeled parts to make sure we had each piece in the right place but the swing scrapes the left front leg if you're not careful when you're swinging.  Really irritating...
