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.

Sizes, Prices & Availability

The Silentnight Double Sided Miracoil Mattress is available in standard UK sizes, including Single, Double, King Size, and Super King.

Prices are typically competitive, especially given the double-sided construction.
