Sealy's PostureTech spring system
Exclusive to Sealy's mattresses, the PostureTech spring system is designed to provide you with targeted support to the areas of the body that need it most. The Mellbreak offers an extra firm support tension, best designed for people who prefer to sleep on their back or stomach, in addition to being affected by back pain. The extra firm tension can provide the extra support needed to help combat such pains. This is exactly why Sealy has included a Powerpack in the centre of the mattress to provide additional support to the lumbar area, keeping sleep disturbance at bay.
