Unlike other manufacturers that mass-produce their uprights, Steinway & Sons uprights are handcrafted in the same factory as our grand pianos, using the same techniques, conditioning processes, and craftsmen. The result is the world’s finest upright, living up to the Steinway & Sons name in every respect. Our upright pianos take advantage of over 125 patented features and processes, including our patented Diaphragmatic soundboard, Accelerated Action and Hexagrip pinblock.
