Ramp is fine. Light weight and easily folds flat or adjusts to different heights. However, the wood on wood squeaks, which scared my cat.  Also, being so light, I think my cat felt uneasy on it, as it would shift slightly under foot when used over carpet. None of my cats wanted anything to do with it. 4 stars, though, as the ramp is very much as expected and worked as it should. Cats are just picky!
