One of Sealy’s most popular models, the Advantage Sapphire Mattress makes use of both the innovative PostureTech CS spring system and a cushioned, gel-infused Geltex comfort layer to guarantee an unbeatable night’s sleep. Hand-crafted in the UK, the mattress also benefits from a luxurious pillowtop and is finished with the finest fabrics, so you enjoy absolute luxury whenever you hit the hay.
World-beating PostureTech CS Spring System
Sealy's state of the art PostureTech CS spring system is designed to respond to shifts in body weight and provide localised support where you need it most. Each spring reacts subtly to your sleep movements, preventing disturbances on one side of the bed from spreading across the entire surface. The system also benefits from Edge Guard technology - a high-density foam strip placed on the inside of the spring - which prevents sagging, improves durability and extends the mattress' lifespan.
Geltex Breathability and Comfort
The Sealy Advantage Sapphire Mattress utilises the company’s comfort-enhancing Geltex technology. This gel-infused comfort layer relieves the pressure on the parts of your body that feel it most, preventing aches and pains. As it’s a highly breathable layer, it allows air to circulate freely throughout the mattress, helping regulate your temperature and preventing overheating.
Handmade in the UK With a Five-Year Guarantee
All Sealy mattresses are handmade in the UK by the company’s talented artisans. Based in Cumbria, Sealy is renowned for its innovation and has consistently pushed the boundaries of sleep technology with its scientific approach. Considerable experience and expertise go into each design, which is reflected in the quality of every mattress it produces. Sealy are so confident of this, they offer at least a five-year guarantee on all of their mattresses.
The mattress is topped with a plush pillowtop that adds an extra layer of luxury to an already supremely comfortable design. The Medium/Soft rating is fantastic if you don’t require too much support and is well suited to side sleepers. The mattress is also shipped with a five-year guarantee that ensures you’re able to invest in a good night’s sleep without having to worry about a thing.
