Originally I gave it 5 stars, but I've revised my review! It was easy to assemble and the cats do LOVE IT! I have 4 rambunctious boys and it does tip over, but since it's light and small, it's easy to sit back up. The reason i revised my review is that in less than a week, they are tearing up the rope...it's very lightweight and won't hold up to mature cat claws! This would be better for kittens.
