The supportive all-rounder.

Double OptiForm Medium foam over PostureTech 2.0. A comfortable medium feel that still keeps the body properly supported.

Size: King Size (150cm x 200cm)
Firmness: Medium, 7/10
Best for: Side sleepers and combination sleepers who need shoulder and hip relief, without losing support.

Why it's good for your back

  • Not too firm, not too soft. A balanced medium feel with PostureTech 2.0 support underneath.
  • Even weight distribution. Helps maintain a natural posture across the whole surface.
  • EdgeGuard. Firm sides and a maximised sleep surface.
  • Great value. Sealy's newest spring technology at an accessible price.

PostureTech 2.0 spring compressing and springing back

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.

A sagging mattress lets the spine bend; Sealy Sleep Select keeps it level

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. Double OptiForm™ Medium foam: Two medium comfort layers that soften the surface while keeping it supportive.
  5. 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.
  6. EdgeGuard™: A single edge-support system surrounding the springs for stability, durability and a wider sleep surface.
