I needed some extra space in the bedroom, and decided to visit Target. These shelves are about 2 feet wide and are made of maple and particle board. It looks like a simple contraction to assemble, as the instructions are extremely sparse.
There are only four boards which connect with screws which are
then covered with “maple” colored plastic as a cosmetic dressing of sorts. The boards feel fairly sturdy to fit in a little cardboard box.
But after assembling it completely, I get the impression that the shelf is only meant to hold light objects such as knickknacks.
I wouldn’t advise putting very many books ...
