• Active Turns (Hypnos)

  The Hypnos Spring Unit is a special design. With a conventional spring, a continued application of pressure will compress the spring completely. With a Hypnos spring, you can apply a certain amount of pressure and collapse the spring only so far, you have to apply more pressure to compress the spring further.

  This gradual and progressive response from the spring allows for perfect support - not too firm, not too soft. The spring has been treated with various thresholds throughout, known as Active Turns, and it is these Active Turns that allow for the perfect amount of support.

• 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.

• Guarantee (Hypnos)

  The Hypnos Guarantee extends for a Decade. Your new Hypnos mattress or base will have a leaflet with more information, as well as a form to be completed and sent to Hypnos directly.

• 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.

• Turn / No Turn

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

• Turns (Hypnos)

  This relates to the ReActive and UltraSens spring units. The term Turn is the number of points that the spring has been heat treated, therefore the number of pressure thresholds it can respond to.
