Deformation measurement serves to represent a clear negative shape of a lying body. A mattress that performs well should support the body well so that the spine (and all other parts of the body) are kept in their natural curvature. This examination is tested on a normal body type (Type A and Type B)

Mattresses are tested on Body Support with 4 Persons with different body types (Male & Female) in Side Sleeping and Back Sleeping Positions.

A cask-shape roller is used to measure durability and damages. A 140kg roller rolls over the mattress 30,000 times to assess whether a mattress, after usage of eight to ten years, is as good as in new condition.

Using a material testing device, a load is constantly pounding on a specific area on the mattress. The result is used to determine the loss in firmness of the mattress.

Two spherical calottes (according to DIN EN 53579) are moved into the surface of the mattress to assess the ability of the mattress, in the unstressed area between the two calottes, to keep at base level, A good mattress, in the unstressed area, should be able to raise between the two stressed areas and support the body.

Using a material testing device, a load is constantly pounding on a specific area on the mattress. The result is used to determine the loss in firmness of the mattress.

A measuring mat for pressure distribution is positioned on top of the mattress, with a test subject's back lying flat on the mattress. High pressure is indicated in red and blue, low pressure in green or yellow. This test will determine the pressure distribution effectiveness of the mattress for persons sleeping at this position. The lesser the pressure, the better the mattress.

Similar as above, a test subject is asked to lie laterally on the measuring map on top of the mattress to measure the pressure distribution at this sleeping position. High pressure is indicated in red and blue, low pressure in green or yellow. This test will determine the pressure distribution effectiveness of the mattress for persons sleeping at this position. The lesser the pressure, the better the mattress.
