What are the ten largest mattress companies in the world?
May. 01, 2023

As of my knowledge cutoff in 2021, the ten largest mattress companies in the world (in no particular order) were:

  1. Serta Simmons Bedding, LLC: Serta and Simmons are two separate brands under the same company, which is headquartered in Atlanta, Georgia. (Filed for bankruptcy in March of 2023)

  2. Tempur Sealy International, Inc.: Tempur-Pedic and Sealy are two of the most well-known brands owned by this company, which is based in Lexington, Kentucky. (Tempur bought Sealy in the late 2000s when Sealy was in deep financial trouble)

  3. Sleep Number Corporation: This company specializes in adjustable air mattresses and is based in Minneapolis, Minnesota. (Available in Canada for two or three years back in the 90s)

  4. King Koil: This mattress company has been in business for over 100 years and is headquartered in Illinois, USA. (The largest mattress manufacturer in Canada back in the 90s in its heyday)

  5. Corsicana Mattress Company: Founded in 1971, this Texas-based company sells mattresses under several different brands. (Never offered here to my knowledge)

  6. Spring Air International: Spring Air is a US-based company that has been in business since 1926 and sells mattresses in over 40 countries. (Once an important player in Ontario but a series of financial troubles ended that run)

  7. Ashley Furniture Industries: Although Ashley Furniture is primarily known for its home furnishings, the company also sells mattresses under its own brand name. (Available only at their retail stores)

  8. Restonic Mattress Corporation: Restonic is a US-based company that has been in business since 1938 and sells mattresses in over 50 countries. (Briefly an important player when made by King Koil in Ontario in the 90s)

  9. Southerland Sleep: This Tennessee-based company has been in business since 1893 and sells mattresses under several different brands. (Never sold here to my knowledge)

  10. Eclipse International: Eclipse is a US-based company that has been in business since 1905 and sells mattresses in over 60 countries. (Never sold here to my knowledge)
