The Sealy Advantage Emerald Mattress offers industry-leading comfort and a fantastic bounce-back feel thanks to the winning combination of its PostureTech CS spring system and an additional latex comfort layer. Handmade in the UK, the mattress has a Medium rating, making it an excellent choice for mid-weight sleepers who require some support but don’t require a firm mattress. It’s also a great option for back and side sleepers.

Groundbreaking PostureTech CS Spring System

Sealy's pioneering PostureTech CS system helps provide you with edge-to-edge support throughout the night. Not only does this prevent roll-together when sharing the bed with a heavier partner, but it also eliminates the discomfort of 'dead spots' at the edge of the mattress. The spring system provides localised support, relieving pressure on essential contact points and distributing weight evenly. It also ensures that movement on one side of the bed doesn't affect sleepers on the other side of the mattress.

An Additional Anti-Bacterial Latex Comfort Layer

The Emerald’s advanced latex comfort layer facilitates a better night’s sleep. It helps the mattress return to its original position once pressure is relieved, so your mattress doesn’t develop indents or sink spots. This ability to immediately recover lengthens the mattress’ lifespan and means you’ll enjoy better sleep for longer. Latex also benefits from anti-bacterial properties, so your mattress stays fresh.

Advanced EdgeGuard Technology in Every Spring

Sealy incorporates their patented EdgeGuard technology into each of the springs in their Emerald mattresses. This high-density foam strip lines the inside of the springs, reinforcing the structure, extending their expected lifespan and helping to make sure the mattress offers total support all the way to the edge.

All Sealy mattresses are handmade in Cumbria by the company's talented craftspeople. A considerable amount of experience and expertise goes into producing every mattress, and all products are checked before shipping. Your mattress will also have a five-year guarantee, so you can invest in better sleep without worrying that your mattress won't last.


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.


Natural latex provides perfect comfort and support with its ability to naturally contour to your body shape.

29cm Depth

This mattress is approximately 29cm deep.

Medium Support

Good all-rounder for front, side or back sleepers.

Quilted Cover

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

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.

Turning Handles

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

Made in the UK

This item has been manufactured in the UK.

Warranty & Guarantee

Sealy 5 Year Guarantee
