Bests & Worsts Reviews from Amazon

This is a great product. However, the dimensions posted in the details are incorrect. The correct dimensions are: 19.5" high, 15" wide, 23" deep (when expanded and set on floor), and each stair is 5.5" deep (front to back). I'm so pleased that I'm going to order more. I was able to place this one in front of a window and because it is open underneath and when placed on the floor it doesn't interfere with my heater vent on the floor. I also like the height because it is higher than most. I'm ordering another one to put at the end of my bed; it almost reaches the top of my mattress making it safer for my older cats to go up and down the stairs.
