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.
