Flimsy
Color: Oak, Size: 30"W x12"D - 3P
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.

Very well made and solid. All the parts fit together perfectly. Very convenient you can plug in a lamp and charge your phone with the usb ports. Great value for the money.

Perfect

These are the perfect size. A little long cumbersome putting them together. They look very nice for a small nightstand
