Bought the bookcases to add storage space that I urgently needed in my new apartment. When I received them was surprised of how easy it was to assemble them. The only inconvenience was that took a few minutes to get them to stay open while getting them together. The shelves have to be set up in a way that all three hook at the same time for the unit to stay sturdy. After done, I'm completely satisfied how much space they provide and that they can be placed in any room without them clashing with the decor. Will recommend them to anyone searching for good and sturdy shelving unit.
