PostureTech CoreSupport Springs with EdgeGuard Technology

At the heart of the mattress is Sealy’s PostureTech CoreSupport spring system, which responds intelligently to your body weight.

How this system benefits your sleep:

• Springs become firmer as pressure increases

• Extra support under hips, shoulders, and lower back

• Helps maintain healthy spinal alignment

• Twice-tempered springs resist sagging over time

Each spring is enhanced with EdgeGuard high-density foam inserts, reinforcing the mattress edges and ensuring stability across the entire sleep surface.

PowerPack Lumbar Support – Extra Firm Where You Need It Most

What sets the Ortho Plus Bronze apart is the integrated PowerPack core:

• Adds firmness through the centre third of the mattress

• Targets lumbar support for improved posture

• Reduces pressure-related aches and stiffness

This makes it especially beneficial for sleepers with chronic back discomfort.

---

Extra Firm Comfort & Traditional Construction

Despite its firmness, comfort isn’t ignored:

• Soft white fibre fillings add light cushioning

• Traditional hand tufting secures fillings in place

• Breathable knitted cover enhances airflow

The result is a stable, supportive sleep surface with minimal give.

---

Double-Sided Design for Long-Term Use

Unlike many modern mattresses, the Ortho Plus Bronze is double-sided:

• Can be flipped and rotated regularly

• Helps balance wear and extend lifespan

• Ideal for those wanting long-term value

Turning handles make maintenance easier despite the mattress’s substantial build.

---

Motion Control & Edge Stability

• No roll-together design keeps sleepers stable

• Reinforced edges prevent side sagging

• Full sleep surface usable edge to edge

A solid choice for couples, even with its extra-firm feel.
