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.

It does look nice in appearance.
I have given the mattress much time before reviewing. I'm sorry to say it has not worked for me at all and I wish to return it now. I find it lumpy and even heated in an uncomfortable way when I lie on it.

Very firm and super supportive with a hint of softness from the cushion top - ideal for front/back sleepers.

It is not as firm as expected. I would say it as a medium firmness. You can feel the springs when you lay. I would add some money and buy a bit more quality mattress instead of this
