Silentnight Memory Sleep 5\' King Size Mattress Image0 Image
  • Silentnight's unique miracoil system which prevents roll together
  • 25mm body moulding memory foam
  • Filed with Silentnight's exclusive EcoComfort fibres

If you’re looking for a firm mattress yet with the comfortability of a memory foam layer, the Silentnight Memory Sleep Miracoil mattress might be just what you’re looking for. Alongside its innovative way to deliver support and comfort, the mattress also uses its own EcoComfort fibre. These fibres reduce heat build up dramatically, and when combined with a high-density micro-quilted cover, it gives this mattress great breathing qualities.

Miracoil springs

Silentnight have developed their own kind of spring system which offers terrific support. Essentially, it’s a continuous length of interwoven springs, but they differ from standard open coil springs as they run vertically along the bed instead of horizontally. This offers firm support, promoting correct spinal alignment and reduces ‘roll together’ for less disturbance from your partner.

Memory foam

On top of a supportive miracoil system there is an extra layer of memory foam. The 25mm layer allows you to have firm support yet have a soft, comfy layer on the top. Memory foam is body moulding and pressure relieving, eventually returning to its original state when pressure is removed.

the mattress was bought for my adult stepdaughter whilst she is living with us. She required a firm mattress and although the one she tested was not available the one chosen and confirmed by the sales person we bought and have not had any complaints about it.

I love this mattress, I have trouble with my back and the firmness of this matress is perfect. The memory foam layer means I`m comfortable yet supported during my sleep. Would definitely recommend! I also had great service from Mattressman, the delivery guys took the mattress upstairs for me, happy customer all round.

The matress is very sturdy, good quality, I can imagine it lasting a very long time. It is however EXTREMELY firm, not the impression I got from other people`s reviews. In hindsight I would not have purchased as I now wake up with backache each morning. I wish it could be returned and exchanged for something slighltly more forgiving. Also having to sign for a packaged matress (where the signature respresents matress received in perfect condition) is pretty much impossible when no time is alloca

Mattresssman were the only store that were reasonably priced and had it in stock. Delivered next day as promised, within a 1 hour window and the guys took off and disposed of all the packaging for me and even put the mattress on my bed, excellent service. Mattress is firm as I wanted yet comfortable due to the memory foam layer, both the mattress and mattr

Extremely comfortable bed, sleep is fabulous, only negative is that the memory surface feels warmer than my old mattress, just means that you sleep under a sheet rather than a light summer duvet in the warmer months, the other half loves it though

This mattress was a real disappointment. I suppose the main issue is that the "miracoil" system is a marketing gimmick. I purchased a king size of the unit to share with my partner. We are both able bodied, slim and in our early thirties, with no history of sleep disorder or back pain. This mattress makes it almost impossible to sleep for both of us because as soon as one of us turns around, the movement will propagate to the whole mattress and to the other person. We purchased this "miracoil" m
