I didn’t pay attention and wasn’t expecting chipboard for the shelving.  As a result, it smells like chipboard, one corner of a shelf was slightly damaged, but still very useable.  They are pretty sturdy, but a bit of a pain to assemble when working alone.  Takes patience, for sure.  They look like inexpensive shelving, so I wouldn’t recommend if using in a visible spot in your home.  More for the garage or utility closet.  The dimensions were pretty close to what we needed in a storage closet is why I decided to buy.
