Elevate Ultra

The Sealy Elevate Ultra mattress is a premium offering in Sealy’s Posturepedic range, designed to deliver advanced support, pressure relief, and durability. It features Sealy’s patented AlignSupport® coil system for responsive spinal alignment, combined with a MemorySense® ComfortCore™ layer that targets pressure points, particularly in the lower back. Enhanced edge support through UniCased® XT technology ensures stability across the entire sleep surface. Cooling and comfort are prioritized with breathable, gel-infused foams like InfiniLux™, while the SmarTex® and ProShield® mattress cover promotes moisture-wicking and allergy protection. Handmade in the UK and 100% recyclable, the Elevate Ultra is ideal for sleepers seeking firm, orthopaedic-style support with modern comfort enhancements—though it lacks a long trial period, so careful selection of the right firmness is key.

Advanced Spring Technology: AlignSupport®
Our innovative AlignSupport® spring system is the result of generations of craftsmanship, decades of sleep science, and a genuine passion for helping you sleep better. This patented two-stage spring technology begins by gently adapting to your unique shape as you settle into bed. It then delivers consistent, deep-down support tailored to your body—night after night. What’s more, every spring is twice-tempered for enhanced durability, meaning your mattress is built to stay strong and supportive for years to come.
Edge-to-Edge Support: UniCased® XT
Say goodbye to that “roll-off” feeling. The UniCased® XT edge support system wraps around the entire spring unit, using interlocking keys to eliminate lateral movement and maximize usable sleep space. You can enjoy full support right up to the edge, whether you're stretching out or sitting up to slip on your slippers. Designed with coil-inspired air channels, UniCased® XT also boosts airflow for a cooler, more breathable night’s sleep—and a secure, responsive edge when you need it most.
Built-In Breathability: BasePlank
At the heart of the mattress lies BasePlank, engineered to provide lasting structure while encouraging air to circulate freely throughout the core. This hidden hero enhances overall stability and breathability, supporting the mattress’s shape and strength across its entire lifespan.
Targeted Pressure Relief: MemorySense® ComfortCore™
In the centre third of the mattress—where your body needs it most—you’ll find our MemorySense® ComfortCore™, delivering personalized pressure relief to your hips and lower back. This targeted zone cradles your body’s heaviest areas, helping you wake up refreshed and ache-free. Paired with a gel-infused foam layer, it adds a cooling touch while providing long-lasting comfort and support.
Firm, Cool Comfort: Franklin Firm
Ideal for those who prefer a robust, firmer feel, the Franklin Firm combines supportive layers of Sealy Firm foam with breathable gel foam to keep you cool, whether you’re taking a midday nap or drifting off for the night. It’s carefully engineered to deliver tailored support and temperature regulation—all wrapped in a durable, high-quality construction.
Smart, Breathable Fabric: SmarTex® & ProShield®
Sealy’s commitment to comfort goes beyond the inside of the mattress. The outer fabric has been specially designed with our unique SmarTex® technology to wick away moisture and regulate your body temperature throughout the night. Partnered with ProShield®, which is endorsed by Allergy UK, the cover also helps protect against allergens—so you can breathe easier and sleep healthier.
