Hesitated to purchase on line but could not find drawer ladder shelf anywhere in this size. We, put it together in about 4 hours. Definitely needed two to finish construction. Just follow directions, familiarize yourself with parts and it will go together. Need power tool to do a good job. So worth it just do not over tighten.   Drawers fit in specific places, so just keep trying and they will all fit beautifully. Have ordered a similar rolling drawer unit for our next project. Keeps us old timers (72 & 74) sharp.
