Assembly is simple, but it does take time. It took me around 4-5 hours to finish. I wanted my room to feel like an office—like the big ones in movies or offices—and this desk is a decent size length and width. So far it seems quite sturdy; the only problem I have is that the board for the inside of the mini closet storage area is not flush. The board has grooves on the side, that are supposed to line up with some pegs you install inside the closet kinda like a shelf. Mine were no cut to fit in the pegs so it slides if you move it.
