Pretty sturdy and nice over-all

Took me about 30min to assemble. But all parts were itemized well, instructions were good. (and I HATE assembly projects, so this wasn't too bad) ;) Pretty sturdy. The cardboard backing is kinda cheap, but everything was pretty good. I just needed an affordable shelf for our closet to hold some cleaners and extra toys/crafts.

Perfect size for the spot I needed it for.

It's perfect! So easy t o out together. I'm just waiting on my NJ State Foster Care licence so I got it to hold books, toys, games for the kid(s).
