The cat tree is sturdy and the material is of good quality. The height is perfect for our little girl (Skittles 2 1/2 yrs old) to jump up to the top deck. Perhaps extending the lower deck would make it easier for a cat to jump up...especially when a cat becomes older and has arthritis. Skittles jumps up from the floor and not from the bottom deck as she finds that it is too close for her to jump up to the top deck. The toy box is a plus. Overall, a great product.
