It was easy to assemble and didn't require any tools except for the caps on the top shelf. I used a plastic grip to turn the caps. I have weak hands and was able to assemble it without any problems. I used this in the restroom as I didn't want to use over-the-toilet storage. It fit well in the small space and was tall enough to make up for the narrow shelves. The materials won't rust or discolor like metal shelves in the humid bathroom. The black and brown colors easily coordinate with my decor. A good value for my storage needs.
I like that I didn't have to use all five tiers. I used 4 on one and 3 on the other (it was still 4 tall). Definitely consider having something heavy on the bottom shelf to stabilize. The support rods are plastic and the shelves are compressed wood. Looks good from a distance. I am pleased.
