Is the Silentnight Double-Sided Miracoil Mattress Good for Back Pain?

Yes. With its firm feel and Miracoil® spring system, this mattress is particularly well suited to people with lower back issues who need consistent spinal alignment. The edge-to-edge support prevents sagging and helps keep your body in a neutral sleeping position.

If you need pressure-relieving cushioning for shoulders or hips, a memory foam or hybrid mattress may suit you better.

How Firm Is the Silentnight Double-Sided Miracoil Mattress?

This mattress has a firmness rating of 5 (firm).

You can expect:

• Very little sink-in

• Strong push-back support

• A flat, stable sleep surface

This firmness works best for back sleepers, front sleepers, and heavier sleepers.

---

Comfort, Breathability & Temperature Control

Despite its firm feel, the mattress remains comfortable thanks to:

• Eco Comfort Fibres™ that encourage airflow

• Breathable knitted cover

• Open-coil construction that allows heat to escape

It’s a good option for sleepers who overheat on foam mattresses.

---

Motion Isolation & Edge Support

The Miracoil® spring system is designed to:

• Reduce roll-together

• Minimise partner disturbance

• Provide consistent support right to the edges

This makes it especially suitable for couples and those who like to spread out.

Practical Design & Maintenance

As a double-sided mattress, this model should be:

• Flipped regularly

• Rotated head-to-toe

The lighter Miracoil® construction makes turning easier than many traditional open-coil mattresses, helping extend its lifespan.
