The step works but the smell is HORRIBLE!!!!! I have tried all sorts of ways to get rid of the burnt rubber smell on these. I bought two of them and as for a stool they are great, but you can not keep them in the house with the smell. I would think the company would have gotten the smell out before they sent them. It's been a month and they are still outside because they smell bad! If they did not smell I would have given them a 5.
