We recently moved into a new home and purchased this for our out door cat that now is an indoor cat to see outside.  It is the perfect height for a cat to lay on the top and look outside from a standard double hung window without obstructing the view.  The top bed and inner bed could use more padding as our cat is used to the small beds you purchase at a pet store when he is inside.  More comfortable than a barn post when he is outside though!  The scratch roller underneath gets used a lot.  I purchased dark brown so it would blend in and not stand out so much in the room.  Excellent price compared to others I had looked at.  Very sturdy and heavy duty.  Will not tip over like some that I have reviewed.
