Silentnight's world-famous Miracoil spring system is designed to offer perfect anatomical support for a restful night's sleep. The edges are reinforced for maximum sleep space so you can sleep right to the very edge - without fear off roll-off! Enjoy an undisturbed sleep: with individual sleep zones, there's no roll-together either.
Eco Comfort Fibre™
Silentnight's Eco Comfort Fibre™ - soft recycled polyester fibres that are proven to reduce your temperature as you sleep.
The mattress is covered in a luxuriously soft knitted cover with the added benefit of being breathable.
This mattress is hypoallergenic & resistant to dust mites, is ideal for asthma and allergy sufferers, or anyone looking for a healthier night's rest
Provides maximal pressure relief, by spreading more of your body's weight across the mattress - less toss and turning, more restful sleep.
Lower Back Support
Enhanced support where it's most needed in the lower back area means that this mattress provides suitable support for everyone, great or small.
No Roll Together
No roll together - the springs are arranged in personal sleep zones, so you can sleep soundly even if your partner rolls over or moves. You won't be disturbed by their motion, and there's no tendency to roll
towards the middle.
More Sleep Space
Reinforced springs around the mattress edge and a firm rod edge help to make sure that the edge will never wobble, sink or bulge, instead giving you support across the complete mattress surface. You'll be
reclaiming valuable space that's usually lost in conventional less edge-stable mattresses.
Ideal for those who prefer a firmer level of support.
Mattress depth 24cm (9.4") approximately.
No Need To Turn
This mattress is purposely designed to be single sided for your convenience - there's no need to flip it over, but we do recommend that you rotate the mattress regularly.
Made from materials that are 100% free from animal by-products.

The Rio Miracoil Cushion Top Mattress is a member of Silentnight's brand new Select Collection, designed to offer the world-class support you'd expect from Silentnight.
Miracoil springs are designed to provide the comfiest sleep possible. Divided into three separate zones of support, Miracoil ensures that your lighter areas get gentler support whilst still giving your hips and lower back the firmer support they need.
The firm mattress edge means you can sleep safely right up to the edge without having to fear roll-off. Thanks to the top-to-toe spring alignment, there's no roll-together either.
Topping the springs there's a great new innovation: Eco Comfort Fibres™. This clever comfort technology has been proven in scientific testing to keep you cooler while you rest. The "Eco" in "Eco Comfort" is because they're 100% sustainable as they're produced from recycled materials. So you can give back a little bit to the earth, even while you sleep.
The Rio Mattress is finished with a beautifully soft quilted and knitted fabric. It's chemical-free and hypoallergenic too - for your peace of mind and a healthier sleep.
A low-maintenance mattress, the Rio is non-turn. All you need to do is rotate regularly to keep it in tip-top shape.
