Title: They can slide on the carpet
Review: The chair risers are advertised as "nonskid" but they can slide on carpet. Bought these for my elderly father who had hip surgery. His chair is in the middle of the room and when he sat down or stood up the chair slid. He uses a walker so it is dangerous for the furniture to move. Also, I did not think the depression at the top of the cone is as deep as it was described. Probably if the chair backed up to a wall or you don't need a walker they would be OK. Even though I had used them the Stander Company said to return them. I bought them through Amazon and the return process was very easy through Amazon.
Is the review positive or negative?
