National Bed Federation – Bed Product of the Year 2025-26.

The Edison Luxury Plush is the softest mattress in Sealy’s Elevate collection, offering a deeply comfortable and indulgent feel. Designed for those who enjoy a truly plush sleep experience, it delivers a blend of luxury and advanced support.

At the core is Sealy’s unique AlignSupport® spring system. This two-stage coil senses your individual shape as you settle into the mattress, helping to maintain natural posture and spinal alignment. It then responds with the right level of personalised support. Each spring is twice-tempered for strength and long-term durability.

The mattress also features Sealy’s UniCased® edge support, which uses interlocking keys to stabilise the entire perimeter. This gives you more usable sleep space and prevents that “rolling off” feeling, while providing a sturdy seating edge for everyday use. Underpinning it all is the BasePlank foundation, a strong and stable base with air channels to promote airflow through the mattress.

For enhanced comfort, the ComfortCore® sits in the centre third to support the hips and lower back. The Edison Luxury Plush includes a double layer of Sealy’s premium InfiniLux™ foam for a luxurious, resilient feel, along with two additional layers of Sealy Medium foam to create its signature plush softness.

Sealy also pays careful attention to the finishing touches. The high-quality fabric is bold and beautifully crafted, woven with SmarTex® to help disperse heat and ProShield® to keep allergens at bay. Both technologies are endorsed by Allergy UK.

Handmade in Britain and backed by a 7-year guarantee, the Edison Luxury Plush is designed as a nightly retreat — combining softness, support, and expert craftsmanship.
