Silentnight Ortho Sleep 6\' Super King Mattress Image0 Image
  • Silentnight's unique miracoil system which prevents roll together
  • Filled with Silentnight's exclusive EcoComfort fibres
  • Features a hardwearing Belgian damask cover

The Ortho Sleep mattress is perfect for anyone who is looking for a high-quality firm mattress. Alongside the materials and systems used, this mattress is hand-tufted to keep the miracoil system as effective as ever and keep materials in place.

Miracoil springs

Silentnight have researched and developed their own way to create a supportive mattress. It’s called the miracoil system, which is essentially lots of interwoven springs that run vertically along a mattress. Normally, open coil spring systems are similar but run horizontally along the bed. This decreases the chance of ‘roll-together’ and gives the mattress a firm feel, hence why it has been rated firmer on the firmness scale.

Fibres and materials 

If you’re looking for a mattress that ticks the comfort boxes as well as the anti-allergy box? Well this mattress could be right up your street as the mattress is filled with EcoComfort fibres, which are scientifically proven to reduce mites and allergens. Alongside this, they can reduce heat and wick away extra moisture. The mattress is finessed with a soft damask cover, which allows the mattress to breathe out extra heat and moisture.

Was looking for a firm mattress with a comfortable topping, and for me and boyfriend it delivered just that. Considering the cost of the mattress, this is exceptionally good value, and even better than any other Silentnight mattresses I`ve had before. Very pleased. The one-man delivery worked out well too. Reading the other reviews judiciously also helped with the decision.

A good Product and value for money in the long run. I bought beds before and had been looking for cheap ones as could not afford the beds then. But subsequently after a while the beds started giving problems and could not get good sleep and never felt refreshed. So ordered this one have been using the silent mattress before for a double bed one in the main bedroom and was great so decided to go for one and it is really a good bet now I love it sleep well is correctly sized.
