These shelves feel and look very flimsy. They’re hollow, and while the description says they’re made of wood, they feel thinner and less strong than particle board. The brackets are sturdy, and the instructions are clear. They’re easy to install. But, at least for the 12” deep shelves, the bracket poles are shorter than the depth of the shelves, so the shelves sag at the front. Pretty disappointing.
