What the Sleep Expert thinks...
"PostureTech CoreSupport springs adapt in real time, lifting hips and shoulders while a zoned foam layer cushions pressure points. The result is a balanced medium feel that hugs, supports, and isolates movement so you and your partner wake recharged, not disturbed. This technology makes the Advantage Classic perfect for couples, but also for anyone looking to improve their posture as they sleep."
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.

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.
Reflex Foam
Used together with springs, or as the support layer in all-foam mattresses, Relfex Foam is versatile and comfortably supportive.
24cm Depth
This mattress is approximately 24cm deep.
Quilted Cover
The quilted cover is created by stitching the mattress cover and the fillings together, creating a patterned comfort quilt layer.
Orthopaedic Support
Designed to offer a firmer sleep surface, providing targeted support for your back and joints.
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.
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.
Hypoallergenic
Being hypoallergenic, this is the perfect item for allergy sufferers - or anyone looking for a healthy night's sleep.
Made in The UK
This item has been manufactured in the UK.
