I have had this cat tree for almost three yrs now and my Russian blue  loves it .. he utilizes most of its features but the best feature is its the right height for him to check out the world from my front windows ,he has other widows and other ways of looking out but that's his favorite window its still holding up and is sturdy I just put a small bath rug on top to make it a little more plush so three yrs and still going ....
