This is by far the most difficult assembly I have never tackled. The main issue is that all of the holes predrilled to receive the screws did not work they were not big enough so they had to be enlarged first. This was the biggest pain in the neck and it took me over five hours on two different days to complete it. Had I known the difficulty and the fact that the wood would split when the screw holes were enlarged I would’ve never purchased this desk. Don’t waste your time or money on this one.
