Assembly was easy, each piece is clearly labeled and all connections aligned well. One flaw with the design of this particular u it is the number of mattress support slats, the gaps between will cause a mattress to sag down so you'll need a piece of plywood or go to the local hardware store to get more slats made to rectify that issue.

Reason for 3 stars is due to major delays in shipping. While calls to customer service were polite and attempted to help, never lead to answers as to where the frame was after it shipped and sitting in some warehouse.
