My kitten loves her tree! It's very sturdy, even on carpet. She sleeps on the very top during the day and it is nice and soft. At night she likes to sleep in the middle house. She's constantly running up and down and playing with the rope. Definitely a great purchase! Shipping was reasonable and on time. It's also not too tall which is nice. It sits perfectly in the corner of the room. I would definitely recommend this cat tree.
