Very good quality sturdy tree. 

I bought this  for my senior cat to use as steps up to the kitchen counter.

Recently he's having difficulty jumping beyond a certain height due to arthritis.  

 I needed something over 30 inches in height . 

I looked at all of the pet steps on the market but none of them are well designed IMO.

It took a couple of days for him to take to it but he's now using it regularly.
