We guarantee to beat ANY online or instore quote for this mattress*   *FLEX option is ideal for adjustable beds, or properties with tight access which require the mattress to bend* Not too firm, not too soft, the Blake offers a medium feel that is a real crowd pleaser. Our unique Posturepedic technology is designed to offer genuine support that everyone can feel, true comfort that everyone deserves and dependable durability that you can always count on. It all begins with a precisely engineered spring system, developed by our team of experts and totally unique to Sealy. AlignSupport™ is a two stage coil design, sensing and responding to your individual shape as you sleep. As your body relaxes into the mattress, the springs sense your shape, maintaining your natural posture and spinal alignment. AlignSupport™ then springs into action and applies the correct level of support, creating a feel that is completely personalised to you. On top of this, the springs are twice tempered making them even more resilient and durable.   NO MORE ROLL OFF NEAR THE EDGE Every Sealy Posturepedic is UniCased®. The proprietary keys lock into place for the ultimate stability, bringing structure to every point around your mattress, meaning that you benefit from a larger usable sleep surface. It also removes the “rolling off” feeling when you are asleep or getting ready for the day ahead. Sturdy and supportive, UniCased acts as the perfect seating edge for putting your socks or shoes on. The ComfortCore™ is placed in the centre third of the mattress, positioned in the perfect spot for targeting your hips and lower back, providing that all-important pressure relief. Teamed up with a combination of Sealy Medium and Firm foams, the mattress offers a sumptuous, cocooning feel as you drift off to sleep. Woven with SmarTex™ and ProShield® technology to disperse heat away from the skin and provide a cooler and cleaner night’s sleep.   At Sealy, it’s our mission to create mattresses that last and that’s why all Sealy Posturepedic mattresses come with a 7 year guarantee. Handmade right here in Britain.   We guarantee to beat ANY online or instore quote for this mattress* *based on beating one quote only from another retailer (we can not go back & forth).
