In general terms, point elasticity specifies the resilience or surface properties of a mattress. If a mattress yields only at the point where pressure is exerted, one speaks of point elasticity. A point-elastic mattress gives way only at pressure points and ensures correct orthopaedic positioning of the vertebral column. As opposed to surface elasticity wherein the pressure is cushioned over a large area and not exclusively at the pressure point. To prevent damage to the posture, a point-elastic mattress is recommended because it adapts perfectly to the body shape and it does not allow any space between the body and the mattress.

Why is point elasticity important?

Depending on weight and sleeping position, different body parts sink to different depths on the mattress. In order to avoid malpositioning of the spine, it's important that the body parts that sink deeper are well cushioned while supporting the rest of the body. As a side sleeper, for example, the body parts to be cushioned are the shoulders and the pelvis. Especially for people with back problems, a point-elastic mattress is recommended, since it keeps the vertebral column in its natural position.

Point-elastic Mattresses

In general, the higher the volume weight, the greater the point elasticity.

Examples of point-elastic mattresses are:

  • Cold foam mattresses – their large volume weight (at least RG60) allows for orthopedically correct sleep.
  • Pocket spring mattresses – here, the number of springs determines the point-elasticity of the mattress.
