I needed something for my 11 year old cat who is 18 pounds to get up and down from the bed and couch. I used to have a cushiony step which wasn’t sturdy enough to hold my cat, and she felt uncomfortable just touching those steps. The previous steps I had worked best for my smaller cat who was only 6 pounds. My 18 pounder loves these steps and uses them all the time!! She feels very comfortable walking up and down them. It’s a big help!! I bought the three-stepper and 2 two-steppers.
