Description

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.

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.

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.

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.
Geltex® icon
Geltex®
Geltex® is a gel-infused foam which increases your comfort and body support. Geltex delivers triple benefits to offer the perfect sleep solution: incredible body support, ideal pressure relief and unrivalled breathability.
28cm Depth icon
28cm Depth
This mattress is approximately 28cm deep.
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.
Pillow Top icon
Pillow Top
Pillow top mattresses have the benefit of an additional pillow layer of plush fillings on the top of the mattress, which provides extra luxurious comfort.
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
