This item came to me broken. It is very poor quality. One of the bottom legs is broken. The piece that the foot screws into came detached from the inside of the leg, so it slides in if any weight is put on it, and the entire thing depends on a very tiny piece of plastic that was also broken. There is also no way to attach the sections of legs to each other either, so if you pick it up by a shelf or by the middle or top section of legs it falls apart. I’m left with a lopsided shelving unit that falls apart if I try to move it. I’m very disappointed.
