Basically, the stability of a body means that it is not easily broken and therefore stable. For example, when a stable mass or body vibrates, it always returns to its initial state. Many people are familiar with the term form stability with respect to contact lenses such that form-stable contact lenses are known for their longevity. This applies equally to mattresses wherein one that is form-stable can have a long lifespan even at high load. Its longevity is ensured by the fact that a mattress core made of form-stable materials always returns to its original position. This keeps the mattress comfortable and prevents indentation.

Form Stability as a Quality Feature

Form-stable mattresses are characterized by a weight of at least 40 kg/cubic metres. Depending on the weight class, a different room weight value is recommended.

The Mattress:

  • is durable
  • maintains your lying comfort over a long period of time
  • does not form indentations

Which materials are form-stable?

Both supporting cold foam and viscoelastic foam, as components of the mattress core, are known to be very form-stable and long-lasting. Both foams are very resistant and find their original shape even after a long pressure load. This counteracts the formation of indentations. The body is supported and is stable in an orthopaedically correct position without bending. No matter what type of sleep - health problems such as back pain and neck pain can be avoided. In addition to the longevity of a mattress and its form stability further properties such as climate regulation and breathability are very important.
