The Church Seat Company of Holyoke, Massachusetts, was founded in 1904 by Charles F. Church. It was the first company to bring a white toilet seat to the market, using a process of forming white pyroxalin around a solid wood core. This seat achieved immediate acceptance by the public and also by the plumbing trade, where varnished oak and mahogany were in vogue. A year later, Church built another plant in a nearby woodworking town to increase manufacturing capacity. This growth helped Church to become the recognized leader in the toilet seat industry, as stated by its slogan "The Best Seat in the House."

By 1930, Church had purchased a rubber stamping plant in Massachusetts to mold hard rubber seats for the commercial trade, but the outbreak of World War II caused crude rubber resources to be diverted. Church converted its presses from rubber to plastic and began molding parts for the Armed Forces. This experience catapulted Church into the plastics age. New product lines such as plastic wall tile and melamine school furniture were introduced, bearing the consistency and quality of the Church name.

Through the years, Church grew as a division of the American Radiator & Standard Sanitary Corporation with manufacturing facilities topping 200,000 square feet. In 1962, an additional 64,000 square feet were added to allow Church to begin manufacturing compression-molded wood seats. After many years as an integral part of American Standard, the toilet seat line was acquired by a Massachusetts firm, Forbes-Wright Industries, in 1975. Bemis acquired Church from Forbes-Wright in 1983.

Today, quality continues to be at the heart of the Church Seat Company, now owned by Bemis Manufacturing of Sheboygan Falls, Wisconsin. With manufacturing and nationwide distribution facilities in a centralized location, Church is always ready to meet the needs of any job and is still "The Best Seat in the House."
