What the Sleep Expert thinks...

"Our double-sided Miracoil gives you firm, even support without the weight of a bulky mattress. The head‑to‑toe spring rows stop roll‑together, reinforced edges add space to starfish, and Eco Comfort fibres keep things cool—just flip seasonally and you’re set."

Over 60 years of expertise and innovation go into every Silentnight mattress, and the Double-Sided Miracoil Mattress is no exception. The patented Miracoil system uses a double-spring design to provide improved pressure relief and support, but in a more compact design, making the Miracoil mattress lighter and easier to move. The edge-to-edge support design gives you more personal sleeping space – ideal if you like to spread out (or ‘starfish’) at night!

Unless you actually want to, there’s nothing that will disturb your sleep more than ‘roll together’! Because of the Miracoil design and edge-to-edge construction, the Double-Sided Miracoil mattress eliminates roll-together and motion transference, so even if you wriggle around you won’t disturb your partner. The reinforced edges give you more room to spread out, creating the perfect environment for a restful night’s sleep.

Eco Comfort Fibre for a greener mattress

We’re all looking for ways to reduce our impact on the planet, so Silentnight has gone the extra mile to utilise 100% recyclable Eco Fibres in their latest mattress designs. Made from sustainable sources, they’re breathable and have been scientifically proven to keep you cooler while you sleep.

NBF-approved and made in the UK

The Silentnight Double-Sided Miracoil mattress is approved by the National Bed Federation, so you can be sure it’s been made to their exacting standards. The mattress is made in the UK and is hand-finished for that premium-quality look.

Turnable for a longer lifespan

As the mattress has fillings on both sides (hence the name Double-Sided!), you can turn this mattress regularly to keep it in tip-top condition. It’s easy to turn too, thanks to the lightweight construction. A firmness rating of 5 means no matter which side you pick you’ll always get maximum support and superior comfort levels, thanks to those clever Miracoils!

For me this mattress is ideal, firm but not to firm. I suffer a bit with lower back pain and the first time using the mattress noticed how superior it was to the old cheap foam one I had been using. Very happy with purchase.
