This sit to stand mobile laptop desk is great!   I have a business that requires me to move around with my computer a good bit.  I was tired of trying to find a clean place to put it, and this does just the trick!   I don't have to mess up all of my papers, just to have somewhere to sit my laptop.   It assembles very easily and rolls great!   It has adjustable height for sitting or standing.   I am absolutely in love with this product!
