My wife and I used this "shoulder dolly" to load an 800 pound upright grand piano onto a dolly, and to move some dressers and whatnot.  The shoulder dolly is TRULY amazing!  Be certain to pay close attention to the instructions for using the dolly, because "pushing away from the object you are lifting" rather than using your back or legs to lift is VERY important, and although it is non-intuitive, lifting this way using the shoulder dolly is SO easy.
