High elasticity

Mattress cores in latex foam pledge an unsurpassed natural elasticity and flexibility. The unequalled point elasticity only yields at the point where the load is applied. The mattress perfectly adapts to the body contours, thus ensuring that the spinal column always keeps its natural line, whether you lie on your back or your side. Mattress cores in latex foam can be perfectly combined with a flexible, a fixed and a box spring base. 

Elasticity 

The elasticity is measured according to the European EN ISO8307 standard, also known as the ‘ball rebound’ test. This test measures the extent (in %) to which a steel ball (or marble) bounds back upwards, compared to its original height. The higher the rebound percentage, the more elastic the material is.

The concept of point elasticity highlights the importance of the elasticity at a particular touch surface. The material only yields at the point where the pressure is exerted and reacts to each instance of pressure with an equivalent counter pressure.

Point elasticity 

Latex foam mattress cores boast exceptional point elasticity. As a result, they ensure excellent conformity: the mattress moulds itself perfectly to the shape of the body. The spinal column will, as such, always form a straight line when sleeping on your side, while forming its natural double S curve when lying on your back. Point elasticity is highest in mattress cores with a large amount of natural latex, thus implying that these mattresses guarantee the best conforming performance. To further boost that performance, many mattress manufacturers integrate ergonomic zones in the latex foam. By, for example, including conical recesses with a larger diameter in the shoulder support zones, a softer zone is created. In this way, the shoulder can sink down deeper into the material when the sleeper is lying on his side. Recesses with a smaller diameter in the hips support zone ensure more firmness there, to support this part – which is the heaviest part of the body. In the lumbar region, it is good to include an ergonomic zone that is 8 to 10% firmer than in the hips support zone, to make sure that region gets optimal support.
