• 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.
  
  

• Fibre Most mattresses will have layers of fillings under the surface to increase comfort and separate the spring units from the surface. The most common fillings used in mattresses are cotton, wool and polyester among others. Mattresses require fillings to create a soft surface tension on which to sleep. The fillings normally compliment the internal spring unit by adding comfort to the support offered (by the spring unit) The tension of the surface fillings can be tuned by the density in which they are packed as well as by the method in which they are bound together. Tufting results in a slightly firmer feel than quilting.
• 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.

• Orthopaedic

  Orthopaedic mattresses are usually the firmest mattresses on the market. A common mistake made by those with back pain, is to assume that a firm Orthopaedic mattress will be the solution. Personal comfort and a correct diagnosis of the cause of the pain should always be saught before purchasing an Orthopaedic mattress. 
  
  Many brands have 'Ortho' mattresses. Terms used include 'Backcare' or 'Orthocare' and the theme is generally to produce a firmer feeling mattress. The idea is to create a mattress that the body can rest on without sinking in and bending the spine, causing pressure to build up. However, if a lighter person lays on a firmer mattress, they will find the spine will not align correctly as the loaded parts of the body (shoulders, hips etc) are not sitting correctly. For more information on the causes of back pain, click here or read about another solution in the Zoning description.

• Turn / No Turn

  Some mattresses require turning over, to aid even settlement. Others do not require turning, but will still require rotating.
