If you suffer from back pain or just can’t seem to get comfortable in bed, your mattress firmness could be to blame. Plush, soft mattresses may feel cozy at first, but they often fail to properly cradle the body and align the spine.  Firm mattresses provide durable reinforcement for your body so you fully relax into healthy spinal positions overnight. The result is fewer sleep interruptions, less tossing and turning, and waking up recharged instead of sore.

This cradles areas like the shoulders and hips just enough while preventing sinkage around the midsection.  The transition layer uses Helix’s proprietary Helix Dynamic foam for enhanced contouring and bounce. At the core is an 8-inch pocketed coil unit reinforced at the edges for optimal edge support. Strategic zoning concentrates reinforcements in the lumbar area to promote healthy spinal alignment.
