It’s not a “high quality “ shelf but I wanted something for my plants. I ended up putting grow lights on the bottom of the shelves. I wish the shelves were a little larger but I couldn’t find something to fit the size needed for my bedroom so overall it works well. I didn’t realize this was a shelf intended to nail into the wall (which I didn’t do) since my  plants are in front of a window. I’d give up a 4 out of 5 on sturdiness (without the wall nail). Overall it works well. It was very easy to assemble. I would recommend to those looking for a small shelf for lightweight items.
