This wall unit was shipped promptly, arrived on time and undamaged, and I was able to assemble it easily by myself. The trickiest part was, installing each of the shelves in the side units, I had to carefully hold up one side of the shelf while threading the bolts into the other side. Other than that it was easy to follow the simple directions. I deducted one star because of the absurd amount of styrofoam used to package the parts in the two shipping boxes. My area does not have styrofoam recycling so it has to go to the landfill. I really wish companies could find another way to package their products using ALL recycled and recyclable materials. The unit looks great in my living room and when I move it will be simple to remove just the center section of shelves shelves
