Easy to put together, and stackable. That being said, there will be a hol on either side of the top that will be visible if not stacked (see picture above). The holes are used when stacking, as a peg is placed in the top of one and connects to the bottom of another.   The only negative is that the backing is not mdf, but rather backer board that you tack nail on. Other than that it’s  a nice piece for the price.
