• Breathability

  Mattresses need to breathe. With the amount of fillings and areas of space within a mattress, they can quickly hold heat and moisture. Over time this can influence the way a mattress behaves and also effect the life span of a mattress. 
  
  Manufacturers have developed different ways of tackling the problem of Breathability in mattresses. Some brands have used vents to allow air to pass through the mattress. Some brands use state-of-the-art materials to cover the mattress, such as Coolmax or Outlast. Memory Foam has a reputation of storing heat and moisture, as foam requires heat to soften up.Memory Foam brands have overcome this problem by applying Coolmax and Outlast, they also use Open Cell technology. This technique is to simply allow the foam to settle with larger spaces between the foam cells. This allows heat and moisture to move freely without getting trapped.
  
  Some mattresses are created in such a way that they do not require any additional Breathability methods. These mattresses are generally the entry level mattresses with Open Coil spring units and not a great deal of fillings.
  
  

• Firmness

  MyNextMattress is developing a new and unique solution to the Firmness scale accuracy. Not seen anywhere else in the World, we will be measuring the Firmness of all our mattresses precisely and in detail.
  
  We are the only company in the Country that will actually measure the Firmness of a mattress and give a grading out of 10. We are always aware that choosing your next mattress can be a difficult and time consuming process, therefore we strive to give as much information as possible on every mattress we sell.
  
  The way our system works is by applying weight to a mattress. We will apply weight gradually and measure the amount the mattress dips. The more weight, the more the mattress will 'sink'. We would then measure the distance the mattress dips and plot these measurements (weight and distance) on a graph. This graph can then be used to tell us the Firmness category the mattress fits into, 7 out of 10 for instance.
  
  Our Firmness Device provides a central rod which we apply weights to, on the bottom end there is a disc which pushes into the mattress. The top of this rod supports the weights and will sink according to the 'give' in a mattress. We measure from this point.
  
  As a result of this unique technique, it will be possible for you to shop by the firmness of a mattress, this is not possible anywhere else.

• Miracoil

  The Miracoil system is the unique spring unit used by Silentnight. Similar to an Open Coil spring unit, the Miracoil spring unit joins the springs from head to toe, rather than side to side. This method reduces the vibrations in a mattress, making for increased comfort and also resulting in edge-to-edge support.

• Pocket Sprung

  Pocket Sprung units are an adaption of the traditional open coil/continuous spring unit. By placing each spring in its own individual 'pocket' (a fabric sock-like pouch), the spring is not joined to any other part of the mattress. The pocket that supports the spring is then joined to its neighbouring pockets and this effect creates a unique feel.
  
  By creating a spring unit in this way, it allows the springs to move independently, rather than sharing the pressure with surrounding springs. This effect allows for much more accurate contour following and a more comfortable feel overall.
  
  If you were to push your hand into a traditionally sprung mattress, the area around your hand would dip/sink too. With Pocket Springs, this sunken area is much more remote and therefore more accurately follows the contours of the pressure source. There are differences in the techniques used to create Pocket Springs, but more or less they remain the same.
