Assembly could be easier. The frames come in 4 pieces which causes most of the assembly issues. The exposed fastener connecting the horizontal bars to the side rails looks particularly low-rent. Attaching the frame to the curved portion of the seat bottom can be a real pain. You may need insert the front bolts and washers loosely and then start the rear bolts without using the washers. Once all 4 bolts are started tighten the front bolts then one at a time remove a rear bolt and reinstall it with the washers.
