I am a senior and I had no problem putting the bookcase together, I did need some help raise the bookcase off the floor.  I purchased two , one thing that I would suggest is to move to the direction for putting on the feet before putting on the front detail piece, that way you can screw the front on through the back, much easier. I am a senior with a replaced knee and can not work on the floor well with my Ethan Allen Desk.
