Very easy to assemble. Sturdy unit. Purchased this unit because of the overall maximum height of the table (38").  Other products I looked at were lower and would not have been as comfortable considering the height of my bed. I'm having back surgery in a couple of months, and wanted something I could easily use to work in bed. My only recommendation would be to add a soft cover for the lip on the left or right side to make it more comfortable to use my trackball while resting my wrist on the lip.
