PostureTech CoreSupport Springs – Firm Support That Adapts to You

At the core of this mattress is Sealy’s PostureTech CoreSupport spring system, engineered to respond dynamically to your body weight.

Key benefits of PostureTech springs:

• Springs become firmer as pressure increases

• Targeted lift at hips and shoulders

• Encourages healthy spinal alignment

• Twice-tempered for durability and resistance to sagging

This adaptive firmness provides deep, orthopaedic-level support while still responding to your movements.

---

Traditional Hand-Tufted Sleep Surface

The Ortho Plus Essential features hand tufting, a traditional technique that secures the fillings in place.

This results in:

• A firmer, more stable sleep surface

• Reduced movement within the mattress

• Improved longevity and shape retention

Hand tufting is typically found on higher-end orthopaedic mattresses and is a strong indicator of build quality.

Comfort Fillings & Breathability

While the feel is firm, comfort is not sacrificed:

• Soft white fibre fillings provide cushioning without sink

• Breathable Belgian damask cover improves airflow

• Pressure is distributed evenly across the mattress

This helps reduce pressure build-up while maintaining a supportive feel.

---

Edge Support, Motion Control & Stability

• Reinforced edges allow you to use the full sleep surface

• Less edge collapse when sitting or sleeping near the sides

• Stable construction minimises movement disturbance

This makes the mattress suitable for couples, despite its firmer tension.

Designed for ease of use:

• Single-sided – no flipping required

• Rotate head-to-toe periodically

• 27cm depth provides a substantial, supportive profile
