It's perfect. Great size for my basement ceilings. I've adjusted it to fit comfortably in the corner of my living room by rotating one of the shelves, which also makes it easier for my cats to use. My cat uses it all day every day, including the scratching post and there has been no distressing to the material. 

Easy to assemble. However when screwed to the wall the base is not level. Its still very secure. Plus it could just be my wall.

All in all great product. Study, easy to build and blends into the walls.
