Assembly took 2.5 hours with screwdriver and small hammer, and my 21 year old son. ( He suggested laying out entire contents in stacks like Legos, then build.)  Directions are fairly easy to follow, translation from Chinese to English... well you can tell but pictures of what each step should look like completed helps. Make sure your floor is level otherwise the one support leg in the middle that typically would be effective will not be enough. I cut a pc of wood to add additional support. My house is way over 100 years old, nothing is level or square AND the stairwell doesn't allow assembled furniture up. We assembled in the area it was going. Follow the directions as close as you can, IT MATTERS! This item uses cam lock system and dowel pegs. Love the capacity and the glide of the drawers. Mirror attaches sturdily to the back with bolts. Delighted with my purchase and the price!
