Boasting a winning combination of Sealy's advanced PostureTech CS spring system and wool's remarkable natural properties, the Sealy Advantage Topaz Mattress ensures complete comfort throughout the night. While the spring system extends support across the entire width of the bed, eradicating dead spots, the wool fibre comfort layer offers excellent insulation while remaining wonderfully breathable. The mattress' Medium rating means it's a fantastic choice for mid-weight sleepers who want to balance support with a nicely cushioned feel.
As well as the PostureTech CS spring system and the wool comfort layer, the Topaz also utilises EdgeGuard technology to reinforce the springs and extend their lifespan. This high-density foam strip is placed inside each of the springs, strengthening it and allowing it to offer greater support.
The Topaz design is centred on the incredible comfort of the innovative PostureTech CS spring system. This system is designed to offer targeted support that reacts to changes in body weight and position, relieving pressure on important contact points and keeping you comfortable throughout the night. The springs also prevent roll-together and prevent one partner’s tossing and turning from causing disturbances across the entire mattress by localising their response.
Wool is one of the most useful and remarkable natural materials available to mattress makers. Not only does it cushion and support the sleeper, but it also insulates the mattress while remaining totally breathable. This allows it to regulate and balance body temperature better than the vast majority of other natural or synthetic materials used in modern mattresses. The use of natural British wool in the Advantage Topaz Mattress means you'll always be cool in the summer and warm in the winter, too.
Like all Sealy products, the Advantage Topaz Mattress is manufactured in the UK by the company’s experienced craftspeople. With extensive expertise and an eye for detail, they ensure that every stitch is perfect and that your mattress is put together just the way it should be. Sealy’s trust in their own people is reflected by the five-year guarantee they attach to every product.
