Once it's put together, this is a sturdy and very stylish piece of furniture. The assembly process isn't difficult, just a bit tedious. It took me about an hour to put the bookcase together. Just be careful to make sure to pound the pieces together snugly before you twist the lock nuts. If you don't, small gaps will remain between pieces that could affect the stability. It would also be a good idea to have a second person to help, since these big boys weigh about 140 pounds when built. Overall, this is an excellent product and a good value. As always, the Overstock delivery service is quick and the packaging leaves you with enough foam and cardboard to build a weekend retreat.
