The labor to assemble was about 2  12 hours.  I have not filled it yet but seems very solid.  Its good that it has latch that only lets one drawer open at a time.   It is heavy when flat packed.  I opened box in garage and made four trips to get all parts to room where it would live.
Its doing double duty as a file and TV stand.  Good price and quick shipping from WayFair.  This was the first item purchased from WayFair.
