OMG!  I live in a basement apartment with lots of windows but they are 6 feet off the floor.  Poor cat had a heck of a time getting up to them and I didn't know what to do.  I saw this and thought I'd give it a try.  I put it on a counter that the cat can get up to no problem and then she just walks up the steps onto the window sill!!!!  NO more jumping down and me worrying about her 13 year old body getting hurt.  These stairs were just what I needed.  Thank you Wayfair!!!
