Good size for the price.  Quality is fair for the price.
* Our two 1 yr old average-sized cats are challenged to navigate some of the narrow parts.
* We removed the very top part because it's too small to lay in and the post was wobbly.  Neither cat was interested in it, even with catnip & treat lures.
* The fabric siding of the round cubby is fun!

Overall, it's fair quality for the price if you want a tall structure for your fur-babies.
