I have to admit the quality control for this is questionable. The instructions said not to tighten the screws all the way, and I couldn't agree more. The nutplates on this bed were so far off that I honestly spent as much time unscrewing as I did screwing in. The fitment on one of my joints on the side is absolutely atrocious. Most of the edge finishings were poorly done, one of which left a roughly half inch by 3 quarter inch flap just hanging off of the end of the vinyl. I would say half of the hex heads on the screws more too big to the point where the provided allen key would just free spin. One of the hex heads was completely filled in with metal. Due to my current dire need for an additional bed I absolutely would have returned the product.
