Description

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.

Features
PostureTech CS Springs icon
PostureTech CS Springs
The unique PostureTech springs respond to your body weight to provide deep down support. As your body relaxes into the mattress and pressure is applied, the springs target the key areas of your body to offer support where you need it most. Not forgetting, the springs are twice tempered, making them resilient and trustworthy over time.
Memory Foam icon
Memory Foam
Originally designed by NASA, Memory Foam moulds to your body, giving orthopaedic support and superb comfort. It also helps to overcome the pressure points of the body.
27cm Depth icon
27cm Depth
This mattress is approximately 27cm deep.
Orthopaedic Support icon
Orthopaedic Support
Designed to offer a firmer sleep surface, providing targeted support for your back and joints.
Reinforced Edges icon
Reinforced Edges
The mattress has reinforced edges, so that the full sleep surface can be used. This means more sleeping space - which is usually lost in conventional, less edge-stable mattresses.
No Need To Turn icon
No Need To Turn
A single-sided mattress which does not need to be turned/flipped. One-sided mattresses should, however, be rotated head to toe regularly.
No Roll Together icon
No Roll Together
Individual personal sleeping zones mean that you won't be disturbed if your partner rolls or moves, as you won't feel their motion. There's also no tendency to roll towards the middle of the mattress.
Pressure Relieving icon
Pressure Relieving
This type of mattress gives maximum pressure relief, allowing your body weight to spread across it evenly. This ultimately means less tossing and turning throughout the night and a more relaxing and restful sleep.
Turning Handles icon
Turning Handles
Flag-stitched handles are attached to the sides of the mattress to assist in turning or rotating.
Made in The UK icon
Made in The UK
This item has been manufactured in the UK.
