Save 25% on a bed when you add this mattress to your order

Experience plush, elevated comfort with the Sealy Posturepedic Allegro Plush Motion, standing proudly at the helm of the Elevate collection. At the heart of this mattress is Sealy’s precisely engineered AlignSupport® spring system — a unique, two‑stage design that starts by sensing your shape as you settle in, then responds with deep‑down, consistent support to maintain your natural posture night after night. Each spring is twice‑tempered, making the entire system resilient and built to last.

Every Posturepedic is UniCased®, with proprietary keys that lock into place around the mattress for ultimate stability and a larger usable sleep surface. It removes that “rolling off” feeling and creates a sturdy seating edge for everyday comfort. Beneath it all, BasePlank™ provides the firm, reliable foundation that ties the whole sleep system together, complete with air channels that help air move freely through the mattress.

Comfort is delivered through a layered system: ComfortCore® in the centre third targets your hips and lower back for personalised pressure relief, followed by InfiniLux™ premium foam for a sumptuous, plush feel. A final layer of graphite‑infused latex adds responsive comfort, keeps the mattress cool and fresh, and recovers its shape night after night.

Expertly designed textiles finish the mattress with bold, standout style, woven with SmarTex® to disperse heat and ProShield® to keep allergens at bay — endorsed by Allergy UK for added peace of mind.

Handmade in Britain and backed by a 7‑year guarantee, the Allegro Plush Motion delivers true comfort, genuine support and dependable durability.
