The instructions wasn’t difficult to follow, but it was definitely time consuming. Although the instructions does say to make sure the unit is at 90 degrees prior to attaching the back panel, it’s a little difficult to make adjustments at that point. It would’ve been better if the back had pre-drilled holes to where the back panel attaches, but since it didn’t, I had a hard time keeping the screws straight (there’s not much space to work with). Because of that, if the screw was angled even a little, the wood would break (see attached pictures). The only reason I’m not too upset about it is because of the low price I got it. Thankfully the messed up parts are pretty hidden from view.
