Our cat loves it, scratches on it, sleeps in it. She scratchs the sphere as well as the rope tube. The thick (banana leaf?) is freying from her work, but we got it for her & I'm happy she uses it instead of our furniture. Easy to put together, solid once built, does not wobble at all under our 9lb. hauspanther. The carpet on the base is our least favorite feature, cat's claws got stuck twice, she no longer scratches at it. You can configure the opening of the sphere & the scratch tube in three different positions to fit your needs.
