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.

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 image

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.

Durability and Long-Life Guaranteed image

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.


PostureTech CS Springs

Sealy's unique PostureTech Core Support spring system is designed to respond to the heaviest parts of your body and apply the maximum support you need for a great night’s sleep.

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

This mattress is approximately 27cm deep.

Medium Firm Support

Good for people who change sleeping position.

Quilted Cover

The quilted cover is created by stitching the mattress cover and the fillings together, creating a patterned comfort quilt layer.

Orthopaedic Support

Designed to offer a firmer sleep surface, providing targeted support for your back and joints.

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

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

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

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

Flag-stitched handles are attached to the sides of the mattress to assist in turning or rotating.

NBF Approved Product

Peace of mind and reassurance - the manufacturer of this item is an approved member of the National Bed Federation's Code of Practice.

Made in the UK

This item has been manufactured in the UK.

Warranty & Guarantee

Sealy 5 Year Guarantee
