I have trouble moving at work. I had a laptop on top of boxes and books. Then a friend told me about this company. It took me a while to work up the courage to order this electric desk sit-to-stand converter. I didn't want a brand new desk, but I needed to install multiple monitors and not hurt my back in the process. This desktop converter has arrived fully functional. It only took me another pair of hands to take it out of the box and set it on the table. This is a great investment!
