Lura-Flex Coils

Open Coil

Innersprings are the best-selling, most widely used sleep system in the US and in many countries around the world. Much of their success is due to the fact that they sleep cooler than foam – approximately 28% cooler, according to a study conducted by the Kansas State University Institute of Environmental Research.

Our open coil innersprings not only stay cool, they also use Active Support Technology to support the spine and contour to the individual curves of the body.
