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.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. The mattress is Vegan-friendly too!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.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!
