Super tall, super big sittinglaying areas.
Pretty simple to assemble and the individual parts werent too heavy to move up to the top during assembly.

I only took a star off because my adult cats are a little too big to be able to navigate all the way to the top. Had to modify the build to help them (removed ramp from top so they could make it up to the top, and I took the little elevated sitting pedestal out because neither of my cats fit in itgives more room to climb)
