The sofa is really good, especially for this price. It came disassembled (the drawer is separate, the back is separate, the base is separate), but it was not difficult to assemble it at all. Literally business 30-40 minutes and it is already ready. Everything is intuitive and without instructions. I personally don't have any gaps. Either this is a marriage, or so conceived, but when folding, you need to push it harder to remove the small gap between the back and the base. Perhaps this was done on purpose so that it would fit into the groove and not move forward when you sit on it.
