Sealy have created the Jubilee Superior mattress by combining their Posture tech 660 spring system with a pressure responsive mini pocket springs. The mattress features a soft knitted stretch fabric cover that incorporates Tencel, a new fibre with natural cooling properties & outstanding moisture management. Eco-friendly Tencel fibres are also ideal for asthmatics & allergy sufferers as it’s hypoallergenic & inhibits bacteria growth. On top of the Posture Tech 660 springs is 800 mini pocket springs, each in its own fabric sleeve allowing them to operate freely so the load on one spring doesn’t affect the one next to it. They provide piston like support to each part of the sleeper’s body & are not affected by varying weights & sizes. The result is a spring system that contours your body shape & supports your spine & neck at the point of contact. Sealy’s Posture tech 660 uses smaller diameter springs providing more springs per mattress than standard conventional beds. This increases the comfort & longevity of the mattress. An additional feature, ‘ Edge guard’, is a high density extra thick foam edge that prevents collapse of the mattress edge. You can sleep comfortably right up to the mattress edge with no sensation of rolling off. With Posture tech springs & individual mini pocket springs Sealy have come up with a winning combination providing a superior support & comfort.
