The stairs are lightweight but very sturdy! They were easy to put together in minutes. The dogs were afraid to walk up them at first so I put a blanket over them to make them softer for their tiny chihuahua feet. I love this product it has saved me endless hours of picking the dogs up and put them back down from the couch. I also feel safer knowing that they will not try to jump on or off the couch and hurt themselves now. Thumbs upð
