Why should you choose this mattress?
There is less to go on here than we would like. What we can say: the price places this in Sealy's higher tier, and the four-size line-up from UK Single through to UK Super King means couples and solo sleepers are both catered for. If you're set on a Sealy Posturepedic, this may suit, although we'd suggest asking the retailer for firmness and construction details first, since a mattress with a premium starting price deserves that certainty.
Key features & layer details
Damask cover
A soft, durable damask knitted cover with ProShield and SmarTex treatments. SmarTex is described as a cooling cover and ProShield as hypoallergenic, so it suits anyone who sleeps warm or is sensitive to allergens.
InfiniLux comfort layer
An InfiniLux foam layer that gives the top of the mattress a luxury feel. It forms the cushioning you lie on first, softening the medium-firm feel a little.
MemorySense ComfortCore
A memory foam layer set in the centre third of the mattress as specialist lumbar support. It adds support under your lower back, where your weight sits most.
Firm and Extra Firm foam
Firm and Extra Firm foam layers sit beneath the comfort layers. They give a durable, supportive base for the softer layers above, so the top doesn't sink too far.
AlignSupport coil springs
Sealy's Posturepedic open coil spring system, which senses and responds to body weight. It supports each part of your body according to how much weight it carries.
UniCased XT surround
A full wall around the perimeter of the mattress. It gives edge-to-edge support, so you can use more of the surface and sit on the edge more comfortably.
BasePlank
The foundation layer of the Webber, which the rest of the mattress is built on. You won't feel it, but it holds everything above it in place.
