Sealy Posturepedic Elevate Alto Firm Mattress in 4 Sizes

Description

Sealy

The Sealy Posturepedic Elevate Alto Firm delivers the firmest feel in the Elevate collection, combining advanced support technology with durable, pressure-relieving comfort. Expertly handcrafted in the UK, this mattress is designed for those who prefer a firmer, more supportive sleep surface without compromising comfort.

At its core is Sealy’s patented AlignSupport® spring system, which senses your body shape and responds with deep, consistent support night after night. Surrounding the spring unit, UniCased® edge support and BasePlank technology provide enhanced stability, increased usable sleep space, and improved breathability.

Premium InfiniLux™ foam, combined with firm and extra-firm comfort layers, delivers immediate pressure response and long-lasting performance. The ComfortCore®, positioned in the centre third of the mattress, targets pressure relief for the hips and lower back. Finished with SmarTex® and ProShield® fabrics, the sleep surface helps regulate temperature and promotes a cleaner, fresher night’s sleep.
