• Hypoallergenic

  Put simply, Hypoallergenic materials do not cause the amount of irritation that non-hypoallergenic materials can. Hypoallergenic materials can still cause irritation in some cases, the chances of this are reduced greatly. People with severe allergies and asthma may still have problems with items called hypoallergenic, but the risk is greatly reduced.
  
  Hypoallergenic materials do not omit the same particles and fibres as other non-hypoallergenic materials. These particles are to blame for causing irritation and discomfort and in some cases the irritation can be dangerous. The Hypoallergenic properties of these materials can be created by number of techniques. Some materials (Memory Foam or Latex) are naturally hypoallergenic, others have been chemically treated.

• Latex

  Latex is the ultimate in luxurious natural materials (but can be synthetic in other markets). Latex is actually found in more than 10% of flowering plants around the world. About 20,000 species from more than 40 families. The Latex used in the bedding industry is taken from sustainable sources. Latex is perfect for mattresses because it is soft, hypoallergenic, natural and moulds to the shape of the body. 
  
  Latex used in bedding also tends to be treated in such a way that it can be used by people who have Latex allergies! The technique used is to super heat the Latex unit, freeze it, super heat it and freeze it again. Once this process is complete, the harmful chemicals released can be chemically washed off, leaving it suitable for everyone. Latex is the material Memory Foam has tried to copy. Memory foam  requires heat to mould to the shape of your body and can therefore become too warm for some. Latex does not require heat and is soft at any temperature. As a natural material which requires time and various processes to be extracted, Latex can be more expensive that its rival materials, but the comfort levels achieved are well worth it.

• Zoning The idea behind Zoning is to offer support where it is needed. The body has certain areas under pressure when lying flat. Zones are designed to split the mattress into sections and offer some areas more support than others. The end result will be a straight spine and pressure relieved. Some mattresses are split into 3 Zones, some into 5 Zones and some into 7 Zones and so on. The principle areas requiring support (and therefore their own individual Zones) are the head, shoulders, hips and feet.  The spine should remain level as much as possible when lying on a mattress, therefore the areas with the most weight applied should be slightly firmer to allow for the extra loading. At the same time, the surrounding areas need to compensate for this and will not be as firm to allow the spine to remain straight. The Zoning may be created by simply adding more layers of fibres where needed, or a different type of spring in certain areas. In latex or foam mattresses, it is possible to vary the density of the foam or latex to create different tensions where required. Latex mattresses can also be sculpted in certain areas to remove latex and therefore make certain areas softer.
