Stairs are not as sturdy as I had hoped. They are okay but my dogs (yorkies) don't really care for the steps. They are narrow as other people have stated in their comments but my dogs are small so I don't mind the narrowness. I do wish the foam was a bit more solid so that the dogs would feel safe. I'd buy the wooden stairs that Wayfair has if you want sturdy steps. The material of the stairs is cheap but it can be removed for washing should it get peed on. That's a nice feature.
