Combining Sealy's innovative, comfort-enhancing PostureTech CS System with a layer of adaptable MemorySense Foam, the Sealy Advantage Quartz Mattress ensures a wonderful night's sleep. Boasting total support across the entire surface area, the mattress also benefits from the company's excellent EdgeGuard technology, which reinforces each of the springs with a layer of high-density foam. This lengthens the expected lifespan of the product and extends the support it provides all the way to the edges of the mattress.

Hand-crafted in Sealy's Cumbria-based workshops, the Sealy Advantage Quartz Mattress offers guaranteed quality. A great deal of expertise goes into every stitch, and the experience of the artisans who manufacture the mattresses is apparent in every product.

Edge-to-Edge Coverage with the PostureTech CS Spring System

At the heart of the Advantage Quartz Mattress is the world-class PostureTech CS spring system. This technology is designed to respond effectively to subtle shifts in body weight, position and pressure, allowing it to offer ever-changing support that reacts to your movements throughout the night. By localising support, PostureTech prevents roll-together and ensures that tossing and turning on one side of the bed is not felt on the other.

Moldable MemorySense Foam Makes the Difference to Your Sleep

MemorySense Foam adapts to your body position, cocooning you in absolute comfort and helping you to stay asleep for longer. By moulding to your sleep shape, it targets support to your biggest pressure points, preventing aches and pains in the morning. As the technology responds to your body heat, the mattress naturally returns its former shape once pressure is relieved. However, over time, it will "remember" your most comfortable position, retain its shape and encourage your body to adopt it.

Durability and Long-Life Guaranteed

All Sealy mattresses are shipped with a fantastic five-year guarantee. However, Sealy also adopts several measures to ensure that your mattress is durable, long-lasting and represents good value for money. For instance, EdgeGuard technology is incorporated into every spring. This high-density foam strip reinforces the spring and extends its lifespan, making for a mattress that offers excellent support for longer.
