Directions say it should take 50 minutes to assemble. If you have 2 people with good eyesight and good backs, you might get it done in 2 hours. Maybe! Mine is still not completed because the last step in the directions is so unclear I still can`t connect the top part with the bottom part. I`m waiting for some more savvy friends to visit and help me complete the shelves. For the second set of shelves you need to make sure you get the colored self in the correct place or you get the colored side on the wrong side.
