Extra firm, extra fresh.

Firmness: Extra Firm, 9/10
Best for: Back sleepers, heavier builds and anyone who wants a solid, no-sink surface.

Why it's good for your back

• Maximum support. PostureTech 2.0 with OptiForm Extra Firm gives a decisive, supportive feel that holds your posture through the night.
• Breathes as it supports. MicroCell's open-cell structure lets air move, so a firm mattress needn't feel warm or stuffy.
• Stable to the edge. EdgeGuard surrounds the springs to extend the sleep surface and keep the sides strong.
• Cleaner sleep. Bio-based ProShield®, endorsed by Allergy UK, keeps allergens at bay.

PostureTech® 2.0: deep-down support that springs back

A higher-gauge wire and re-engineered head design give a steadier, more stable base. The coil's unique geometry responds to your shape and spreads your weight evenly, so hips and shoulders are supported rather than left to sink. Twice tempered and tested by Sealy scientists.

What's inside, layer by layer

1. Bio-based ProShield®: Endorsed by Allergy UK. A VOC-free treatment that keeps allergens at bay for a cleaner, fresher sleep.
2. Airstream Fibre: Nestled in the quilt for soft, lasting comfort, replacing the need for an extra foam layer.
3. EternityFibre: Works to reduce settlement, so the surface keeps looking and feeling its best.
4. MicroCell foam: Open-cell, highly resilient and breathable. Soft to the touch, durable underneath. ISCC PLUS certified, TCPP-free.
5. OptiForm™ Extra Firm foam: A dense, high-performance layer that keeps the surface firm and level.
6. PostureTech® 2.0 coil: Sealy's new spring: higher-gauge wire, re-engineered head, twice tempered. Unique geometry distributes weight evenly to support a natural, healthy posture.
7. EdgeGuard™: A single edge-support system surrounding the springs for stability, durability and a wider sleep surface.
