Exclusive to Sealy, the PostureTech Core Support spring system is precisely-engineered to offer consistent deep-down support and comfort, giving your body exactly what it needs to achieve a superior night’s rest. EdgeGuard surrounds the spring unit for added durability and edge-to-edge support. The memory foam layer responds to your body shape as you sleep to relieve your pressure points and provide long-lasting comfort. A combination of Purotex and silky soft Tencel fibres are nestled in the fabric to reduce moisture and allergens that may cause irritation during the night. Endorsed by Allergy UK, Purotex works to keep your mattress clean, fresh and odour free- so that over time your mattress feels just as good as the day you placed it in your home. Adaptive technology also absorbs moisture to regulate your temperature and keep you cool.
