I have assembled many furniture pieces, from sofas and beds to cabinets, drawers, and buffets. I have never encountered such poor material. The only reason it doesn't get 1 star is that the final product (if you manage to get there) is just okay. Otherwise, the instructions are barely existent, the screws are random and in the wrong quantities, and if you drill the holes where the scientists have marked, either the cabinet won't close or the drawer won't close. Stay away unless you want to spend another 20+ euros per piece for assembly, but for 100+ euros, you can find something of better quality.
