Is the Relyon Ortho Superior Extra Firm 1500 Good for Back Pain?

The Relyon Ortho Superior Extra Firm 1500 Mattress is particularly well suited to sleepers with chronic back or joint pain who need very firm orthopaedic support. The high-tension pocket springs help maintain neutral spinal alignment, while the natural fillings provide comfort without compromising firmness.

If you prefer a softer mattress or sleep mainly on your side, this mattress may feel too firm—but for posture correction and stability, it performs exceptionally well.

How Firm Is the Relyon Ortho Superior Extra Firm 1500?

This mattress has an extra firm comfort feel — the firmest support level available.

You can expect:

• Minimal to no sink-in

• Strong resistance across the entire surface

• A flat, stable sleep platform that resists sagging

This firmness is best suited to back sleepers, stomach sleepers, and those specifically seeking orthopaedic mattresses.

---

Comfort, Breathability & Temperature Regulation

Despite its firmness, this mattress remains breathable thanks to:

• Natural fibre and cotton fillings

• Air vents that allow fresh air to circulate

• A Belgian damask cover that promotes airflow

This makes it a good option for hot sleepers who need firm support.

---

Motion Control & Edge Support

The individually pocketed springs reduce motion transfer, so partner movement is less noticeable.

The Edge+™ reinforced side support ensures consistent firmness right to the edge, allowing you to use the full sleeping surface comfortably.

---

Practical Design & Maintenance (Turnable Mattress)

The Relyon Ortho Superior Extra Firm 1500 is a double-sided, turnable mattress, with fillings on both sides.

This means:

• The mattress should be turned and rotated regularly

• Alternating sides helps even out wear

• Regular turning helps maintain firmness and extend lifespan

While it requires more maintenance than single-sided mattresses, the benefit is exceptional durability and long-term performance.
