The build quality of this piece is pretty good for the price. It's not made of the particle board material like a lot of IKEA items, but more of a veneer on MDF type build. Substantial weight and nice finish. 
The assembly is not terribly complicated, as the instructions are clear (except for drawer insertion), but it is time consuming. I'd estimate a couple of hours is average assembly time. It came packed securely and neatly.
