Sealy Holme Mattress | PostureTech™ 2.0 | St James Bed Centre

Sealy Select Medium Luxe Mattress – The Pinnacle of the Select Collection

Sitting at the very top of the Select collection, every detail has been thoughtfully designed, rigorously tested and expertly crafted to deliver long-lasting performance for every type of sleeper.

PostureTech™ 2.0 – Smart Spring Support
At its core is PostureTech™ 2.0, Sealy’s new smart spring technology. This is no ordinary spring. The unique geometry of the PostureTech™ 2.0 spring responds to your individual body shape to provide deep-down support. Delivering consistent support right across the sleep surface, it is designed to distribute weight evenly and help maintain a natural shape and healthy posture. PostureTech™ 2.0 uses a higher gauge wire for greater stability and performance resilience over time. Twice tempered and rigorously tested by Sealy Scientists, it delivers enduring quality making lumpy and uneven mattresses a thing of the past.

PostureTech™ 2.0 support is combined with 1500 micro pockets, Microcell™ and OptiForm™ to conform and cushion, creating a medium comfort feel.

DualEdge™ – Maximise Your Sleep Surface
DualEdge™ pushes the boundaries to maximise the sleeping area of your bed. This unique innovation supports the spring system, reinforcing both the sides and edges of the mattress, stabilising every inch and extending the usable sleep surface. Whether you prefer sleeping right to the edge or simply need somewhere to sit while putting on your socks, DualEdge™ makes the most of your mattress.

Intelligent Comfort Architecture
Enhancing the support system is a premium layer of comfort technology designed for the perfect medium feel:

• 1500 Micro Pockets: Individually contour to your shape for enhanced comfort and tailored pressure relief
• MicroCell™ Foam: Durable and resilient with an open-cell structure that enhances breathability while delivering a soft, sumptuous feel
• Triple Layer OptiForm™ Foams: OptiForm™ Medium Foam + OptiForm™ Firm Foam x2 gently cushion and adapt to your body. The result is a perfectly balanced feel that delivers support without compromising on resilience
• EternityFibre™: Adds lasting comfort and helps the mattress retain its feel over time
• Airstream Fibre: Promotes airflow through the mattress for a fresher, cooler sleep environment
• Bio Based ProShield®: Protective layer using bio-based materials for added peace of mind

Sustainably Designed
Designed with responsibility in mind. From TCPP-free foams to a construction that reduces adhesives and improves recyclability, every layer has been thoughtfully considered — delivering sustainable progress without compromising comfort or durability. It’s exactly what you would expect from the world’s No.1 sleep brand.
