Question: Are the steps on this stool made of metal or plastic?
Document: Wouldn't take anything for this stool. Very stable and I feel very secure when I am on it. Love the locking device so that I know for sure that I am safe. Ordered for me but noticed my husband is using it instead of his ladder. I would very much recommend this to my friends.
i used it outside to clean an awning. the rear legs were in the grass. - THEY POKED THROUGH THE REAR RUBBER PADS.it is useless now.
Answer: no
