Easy to put together, size is bigger than listed and my cat likes the top. One thing I am not pleased with is the material on it is thin but is soft to touch. Lying on it is like sleeping on soft wood. I recommend this but for those who have bigger room to put it, not for large cats and the cat don't mind the hard surface to sleep on. Ladder and hammock is basically for show.

Fairly surdy, easy to put together once you figure it out
Large cats not going to use except on top (surface areas are not big enough to lie on)
