This was an easy unit to put together. I had to assemble two of them. After the first one, it was half the time, maybe 90 minutes for both. They are quite heavy duty and seem to be well built. The assembly uses self locking post fasteners. They seem to be holding up fine, as long as they are not over tightened.  They have a decent amount of storage, and I like that the back is solid wood; not just a "staple on" particle board. These do not look like cheap furniture at all. Highly recommended!
