I put this together by myself (5’6” 150lbs female). I had to prop up one side against my dining table to be able to add other leg etc.  Do NOT use the assembly directions from website on order.  Use the one in the box with desk.  I had a lot of stress until I realized the instructions online were wrong.  It took me about 2 hours to assembly myself.   It is very sturdy and will last.  The crank is silent and so easy to do.  I love the desk.
