Description

The Sealy Advantage Classic mattress combines supportive springs and layers of zoned foam for a blissful night’s sleep.

Inside this mattress is Sealy's unique PostureTech Core Support spring system. The springs are weight responsive and get firmer as pressure increases to offer deep down support that’s long-lasting.

The zoned foam layer targets the key areas of your body and applies support where you need it the most.

Finished with a quilted sleep surface, the mattress offers luxurious comfort night after night.

The mattress is also single sided. Simply rotate it from time to time to improve its lifespan.

Features

Not forgetting, the springs are twice tempered, making them resilient and trustworthy over time.

AI Summary

The Sealy mattress is widely commended for its blend of comfort and firmness, ensuring quality, restful nights of sleep. Its reliable build guarantees great value for money, with durability and a medium firmness level praised by many customers. A few reviewers encountered a strong smell upon unpacking, although this tended to dissipate after some airing. It may lack of handles for easy manoeuvring. Nevertheless, it is often described as a worthwhile investment due to its high standard of quality and its reasonable price. Many customers also highlighted the excellent delivery service.
