Want a firm, traditional mattress that offers long-lasting support and excellent value?
The Silentnight Double Sided Miracoil Mattress is built for sleepers who prefer a firmer, more supportive feel with minimal movement disturbance. Using Silentnight’s patented Miracoil® spring system and durable comfort fibres, this mattress delivers consistent edge-to-edge support and is designed to be turned regularly for a longer lifespan—making it a practical choice for everyday use.
Who Is the Silentnight Double Sided Miracoil Mattress Best For?
This mattress is best suited to:
Back sleepers who prefer a firm sleep surface
Front sleepers needing stable, supportive comfort
Couples who want reduced roll-together
Heavier sleepers needing stronger spring support
Buyers who like traditional double-sided mattresses
Anyone wanting a durable, long-lasting mattress
If you’ve tried softer or foam mattresses and found them unsupportive, this Miracoil model is likely to feel reassuringly firm and stable.
Is the Silentnight Double Sided Miracoil Mattress Worth Buying?
Yes — if you value firm support, durability, and simplicity. The Miracoil® spring system provides even weight distribution without individual pocket springs, while the double-sided design allows you to turn the mattress regularly, helping it retain its shape for years.
This makes it a strong option for master bedrooms, guest rooms, or anyone who wants a mattress that prioritises support over softness.

How Firm Is the Silentnight Double Sided Miracoil Mattress?
This mattress has a firm comfort feel (rating 5).
You can expect:
Minimal sink-in
Strong, consistent support across the mattress
A stable surface that keeps your spine aligned
It’s particularly well suited to sleepers who dislike plush or memory foam mattresses.
Is the Silentnight Double Sided Miracoil Mattress Good for Back Pain?
For many sleepers, yes. The firm Miracoil® support system helps maintain a neutral spinal position, especially for back and front sleepers. It’s often recommended for those who prefer orthopaedic-style firmness rather than contouring comfort.
Side sleepers may find it too firm unless they prefer a very supportive feel.
Motion Control, Edge Support & Sleeping Space
While Miracoil® springs are not individually pocketed, the system is designed to minimise roll-together and improve stability:
Less movement transfer than traditional open-coil mattresses
Reinforced edges prevent sagging and maximise usable space
Ideal if you like to stretch out or sleep near the edge
Breathability & Sleep Temperature
Thanks to Eco Comfort Fibres™ and an open spring structure, this mattress sleeps relatively cool:
Good airflow through the spring unit
Less heat retention than foam-based mattresses
Suitable for sleepers who overheat at night
Maintenance & Longevity
This is a double-sided mattress, meaning:
Turn and rotate regularly (every few months)
Helps prevent dips and uneven wear
Designed for long-term durability
If you prefer a mattress that rewards a bit of maintenance with extended lifespan, this is a good choice.
