Why Choose a King Koil Mattress?

King Koil understands that mattresses are about getting a healthier night’s sleep for people of any shape and size. King Koil achieves this by offering consumers two exclusives that no other mattress company can provide.

1)      A 50 year partnership with the International Chiropractors Association (ICA)

2)      The Perfect Contour Reaction® Coil System

Since 1967, King Koil and the ICA have worked together to design mattresses to help promote proper spinal alignment so you can sleep healthier at night to feel better during the day. The ICA reviews each King Koil product and designates whether the mattress has earned a silver or gold ICA endorsement. To learn more about these endorsements, look into the King Koil World Luxury, World Extended Life and World Luxury Intimate collections on this site or visit your local Sit N’Sleep location.

King Koil’s exclusive Perfect Contour Reaction coil system design, perfectly conforms to your unique body shape and size to properly align your spine, so those muscles that strengthen and support your back and spine, feel relaxed and balanced to help relieve those aches and pains. This design combines over 1000 taller, active conforming coils with our supportive reaction coils. They work together to comfortably support each individual body shape and size to improve postural alignment while reducing motion disturbance.

About King Koil

King Koil proudly designs and builds mattresses in the USA, and has since 1898.

It all began when Samuel Bronstein realized his dream by starting 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 just outside of Chicago, Illinois.
