The connectors between the metal bars (posts and crosspieces) this clothes rack are made of plastic. In particular, the terminals for locking the height adjustment are made of plastic and can slide on the chrome metal pipes. If this happens on one side (as with a 4, which I used), breaks down the frame and the plastic parts become irreparably broken. I recommend this stand for a maximum of shirts and blouses, heavier by no means garments such as trousers and jackets. For all metal racks are probably appropriate, albeit a bit more expensive.
