This cat tree is perfect to fit in front of my single french door for the cats to look out into the back yard.  The platforms are a little small for my cats to lay down or comfortably snooze, and my larger cat (15 lbs) will not attempt to enter the cave.  But they enjoy being elevated to look out and see the birds, and utilize the platforms throughout the day.  It was delivered quicker than expected and was easy to assemble.
