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.\u003c\/p\u003e\n\u003cp\u003eEvery 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.\u003c\/p\u003e\n\u003cp\u003eComfort 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.\u003c\/p\u003e\n\u003cp\u003eExpertly 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.\u003c\/p\u003e\n\u003cp\u003eHandmade in Britain and backed by a 7‑year guarantee, the Allegro Plush Motion delivers true comfort, genuine support and dependable durability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan style=\"color: red;\"\u003eMotion Base Compatible Mattress.\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch5\u003eKey Features\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eAlignSupport Coil system\u003c\/li\u003e\n\u003cli\u003eZip \u0026amp;
