63-75 S. Main
DUBUQUE MATTRESS COMPANY. John KAPP immigrated to the United States with his parents in 1851. They came to Iowa in 1859 and lived briefly in Jackson County before moving to Dubuque in 1860. Knapp served an apprenticeship for three years to learn the business of mattress making and then moved to Chicago for two years. He returned to Dubuque in 1876 and with his father established Knapp & Son.

Knapp's father died in 1879 and John continued the business, renamed the Dubuque Mattress Company, with J. Belzon. (1) The firm had about ten employees in the new factory equipped with a 25-horse engine. Their products were shipped throughout Iowa, Nebraska, Kansas, Minnesota, Illinois and Wisconsin. Dubuque Mattress was considered the pioneer wool mattress factory and the only one west of the MISSISSIPPI RIVER.

In 1880 the company was located at 451-457 4th St.

The Dubuque Mattress Company was incorporated in February 1884 by Knapp and Henry Sauer. Kapp served as the company's president while Sauer held the offices of secretary and treasurer.

Sales receipt

The company was originally a wholesaler. Edward Eisenschmidt brought the company through the GREAT DEPRESSION and then, about 1930, began selling directly to individual customers, institutions and retail customers.

The continued prosperity of the firm has been credited to William Riedel, a graduate of the UNIVERSITY OF DUBUQUE and former physical director of the YOUNG MEN'S CHRISTIAN ASSOCIATION (Y.M.C.A.). Riedel married Eisenschmidt's daughter and then learned the business of mattress manufacturing. He continued to manufacture mattresses until around 1990 when this work was carried out by Comfort King in Dubuque. The business was closed in 1999.

In 2003 Doug Dolter purchased Dubuque Mattress.

In 2010 and 2012 the company's address was 3220 Dodge Street.

In 2015 the address was 2794 University Avenue.
