I bought this product for two of my sons. I was looking for something that was not a lot of money and would act as storage, in addition to being attractive. I found this product to be the perfect solution. They are made from laminate/mixed woods and hold a lot of CD's and other items.
They arrive unassembled in flat boxes. My two boys, 13 and 17, assembled them on their own, respectively, using a drill with screwdriver bit, and hex tool. The headboards were completed and up within no more than 45 minutes. (Yes, I have "handy" kids.)
They are attractive and fairly sturdy. The picture on the site appears to show a black interior. However, it is inaccurate as the interior of the shelving is Cherry -- just slightly darker in color. Other than that, the low cost is a great value.
As for further assembly...we have these against a wall and did not attach them to the metal frames. If you have younger children, who tend to jump around a bit, I would suggest attaching them to make the entire assembly safer.
