the boards screw holes did not match up with the screw holes in the frame on both frames - one the first frame it was boards M & N but on the second frame it was almost as if the boards would fit a full size bed frame not the twin size.  had to loosen the main frame to accomodate the boards to the point that the frame seemed too loose - also despite all efforst, the last board would not line up and only one screw would fit.  also foot mechanism would go up but had to be pushed down.  Over all quality of the frames was poor.
