Great size! Not too big but my cats love climbing to the top and perching. It was very easy to assemble, only took my husband about 25 minutes. It is very sturdy and has a clever design that gives my cats a ton of options to explore. My cats love it!

Pros: Tall, not too big and very sturdy
Cons: Charged more for different colors.  My budget limited my options to brown which does not match my living room.
