An upright piano is a baby grand piano that has been designed to be oriented vertically instead of horizontally. Upright pianos are similar to console or spinet pianos since all three are vertical, but uprights are taller (5’-6’) and usually have a full cast iron grand frame (harp) above the sound board. Because of the stresses involved with a cast iron harp, the frame of an upright is extremely robust making them even heavier than a grand. A fully dressed upright can way in excess of 800 pounds. Upright pianos fell out of favor in the post WW2 era due to the expense and difficulty moving them and are rare today. Upright pianos will usually have an extra handling charge to offset the extra labor needed to move them and are almost impossible to move up a flight of stairs unless you have four extremely strong men to assist.
