Shop for Innerspring Mattresses

King Koil isn’t the King of Koils for just our looks. We have taken the innerspring design to a new innovative level with our Contour Flex EC system with K2 Edge and our exclusive Perfect Contour Reaction™ coil system. These encased coil designs not only enhance your sleeping experience but a healthier night’s sleep by providing a proper spinal alignment. All King Koil mattresses are designed and built in the USA since 1898.
