Pay for assembly!!! This took me over a week to build and it was so hard. The drawers are still lopsided after so many attempts. You do not need to attach to wall. It will stay. This isn’t an ordinary furniture that you build… it comes in MANY pieces. It will frustrate you. I think it was worth it. But seeing so many reviews someone needs to say the truth. I also had to glue the front of the drawers because it wouldn’t connect with jus the screw. Just keep this in mind.
