The Sealy Pearl Deluxe mattress is an orthopaedic design for those who prefer a firmer level of support or those who suffer from back pain. This carefully designed option uses the very latest technology as well as traditional, hand-crafted manufacturing skills to create a mattress that not only looks good, but one that feels great too, ensuring you get a restful and relaxing night�s sleep. The inclusion of smart fibres regulates temperature and humidity levels, making this a healthier option, especially for those who suffer from dust or canker-related allergies or respiratory conditions such as asthma.The mattress is 27cm deep, with a zoned foam layer that targets key areas of the body to prevent aches and pains by offering varying levels of density and support. EdgeGuard technology prevents the sides from sagging, prolonging the life of the mattress and giving you edge-to-edge support all night long. Made in the UK, the mattress comes with a 5-year warranty for complete peace of mind.Double-sided mattresses can be hard work, especially when you have to flip and turn them every few months to get the best out of them! The Sealy Pearl Deluxe mattress is a single-sided option, so all that heavy work is avoided. However, to avoid any dips from forming and to prevent fibre compression that may reduce the comfort levels of your mattress, we do recommend that you rotate it from head to toe every few months.At the heart of the Pearl Deluxe is Sealy�s unique Core Support system, delivering outstanding support and comfort that responds intuitively to your movements all night long. So whether you sleep on your front, your side or your back, you get that deep-down support you need for a restful and restorative night�s sleep.The Pearl Deluxe from Sealy uses patented smart fibres to regulate both humidity and temperature throughout your mattress, keeping things cool and fresh even on those hot summer nights. Purotex, which is endorsed by Allergy UK, keeps things clean, fresh and odour-free, preventing the growth of bacteria by allowing the air to circulate and reducing moisture. Soft, smooth Tencel fibres stop those allergens from taking up residence, while Adaptive technology works hard to keep temperatures down, making this an ideal choice for those who suffer from night sweats or hot flushes.
