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.

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.

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.
