Frequently Asked Questions What is the best firm mattress for side sleepers who want cooling features? The Helix Twilight Luxe combines a firm support profile with GlacioTex™ Cooling Cover, offering targeted pressure relief for side sleepers and continuous cooling verified by material tests. How does the GlacioTex™ Cooling Cover compare to a regular TENCEL™ cover? GlacioTex™ uses advanced heat-dissipating fibers for immediate, measurable cooling, while TENCEL™ is naturally breathable but less active in thermal transfer, based on independent lab results. Which mattress type helps prevent hip and shoulder pain for side sleepers? Mattresses with zoned memory foam and coil support—like Helix Twilight Luxe—support proper alignment and significantly reduce pressure in clinical studies. Is a pillow top mattress with lumbar support good for people who toss and turn? The extra cushion and zoned lumbar design stabilize the spine and adapt to movement throughout the night, reducing waking and improving sleep continuity. Are firmer mattresses better for people who don't like sinking in while sleeping? Yes. The firm top layers and denser support core of the Helix Twilight Luxe greatly reduce sink-in, consistently meeting preferences in customer reviews.
