Sealy Spencer Plush

Standing at the helm of the Elevate collection, the Sealy Spencer Plush Mattress delivers luxurious, sink-in comfort without compromising on support. Designed for those who love a softer feel, it combines Sealy’s renowned Posturepedic® technology with plush comfort layers for a truly refined sleep experience.

At its core is Sealy’s unique AlignSupport® spring system, a precisely engineered two-stage coil design developed by Sealy’s sleep experts. The springs sense and respond to your individual shape as you settle into the mattress, helping maintain natural posture and spinal alignment. As your body relaxes, AlignSupport® applies the correct level of deep support, creating a feel that’s completely personalised. Each spring is twice tempered for enhanced resilience and dependable durability year after year.

Every Sealy Posturepedic mattress features UniCased® edge support, locking structure around the entire perimeter for exceptional stability and a larger, more usable sleep surface. This removes the “rolling off” feeling and provides a sturdy seating edge. Beneath the spring unit, BasePlank technology delivers a solid, trustworthy foundation with integrated air channels to promote airflow throughout the mattress.

Comfort is taken to the next level with ComfortCore™, positioned in the centre third to target the hips and lower back for ultimate pressure relief. This is paired with Sealy’s luxurious InfiniLux™ foam, alongside layers of medium-soft foams, creating the plush, cocooning comfort the Spencer is known for.

Finished with bold, premium fabrics woven with SmarTex® and ProShield® technologies, the Spencer Plush helps disperse heat away from the skin while protecting against allergens for a cooler, cleaner sleep surface—endorsed by Allergy UK.
