I am not going to lie, I bought three of these and the first one I put together took me awhile. After the first one it was pretty easy to do and the second two took a little less than an hour a piece with interruptions.  You have to not tighten anything all the way until you have all the screws in them tighten each a little at a time.
After you get 2 drawers done you don’t even have to look at the directions.  Completely worth the price. I used one for makeup and the other two for filing cabinets. Make sure you secure the bottom of the drawers or they will move and your items in the drawer will fall out. I used a tiny nail to keep them tight in the back of each drawer!  I priced these a lot and these are completely sturdy and worth every penny!
