This is the third closetMaid cube bookcase we’ve bought. It’s extremely easy to put together. The simple design makes it difficult to make a mistake during assembly. I did it during my lunch hour and still had 15 minutes to eat. That 45 minutes includes dragging the box upstairs, getting it open, assembly, and clean up. The first two we’ve had for 4 years and they still look great. They have held up to two rambunctious boys. They are simple, but extremely functional and durable.
