DeepSleep mattresses are constructed using SimFlex® Continuous Interactive Coil Technology to respond efficiently to your body.
SimFlex interactive open coils firm up when compressed and are fastened together at the top and bottom to form a resilient, interactive support system. Interactive support means that the coils work together to gently contour to your overall body shape and weight, creating the environment for a deep and restful night's sleep.
Continuous Interactive Coil Technology provides your mattress with firm support and classic comfort.
And every DeepSleep model is NON-FLIP, so you’ll never have to flip your mattress again!
