They are extremely small. One of the side panels was defective so we had to improvise to make it work. The groove where you slide the backing in was carved out on the wrong side, so we just left it open in the back. At first we thought we were doing something wrong, but when we compared the side piece to the picture in the instructions, we realized they didn’t match up. Doesn't look great because the groove on one panel is exposed on the front of the nightstand instead of the back because of the defect. We kept the nightstands because we didn’t want to repackage everything and send them back, and it also worked out that our walls are white, so looks fine that it’s just open in the back. They were really inexpensive so I guess you get what you pay for.
