In 1898, Samuel Bronstein realized his dream: he founded United States Bedding in St. Paul, Minnesota. What started out as six employees in a small factory has steadily grown. Throughout the early 1900s, US Bedding added employees, expanded manufacturing and became innovators in the industry. During the 1930s, US Bedding greatly improved the bedspring and was looking for a new name for its product. The King Koil name was born. Today, King Koil mattresses can be found in more than 90 countries throughout the world, with its worldwide headquarters located in Avondale, AZ.
