More energy

Did you know that we turn and toss 30 to 60 times in our beds at night (after research by Prof Dr. R. Cluydts)? You wouldn’t want your mattress to hinder your natural movements, would you? The Innergetic mattress core ensures that we can turn and toss in bed, without the slightest impediment. In this way, we use far less energy. More than that, we regain energy while we sleep – so that we can truly speak of ‘a revitalizing night’s sleep’. The amount of energy that the mattress core returns to the sleeper is calculated on the basis of the hysteresis curve.

Hysteresis curve

The hysteresis curve is measured by comparing the power needed to compress a mattress core with the compression itself, in a ‛load deformation curve’. Concretely: in the test, the mattress core is compressed until a maximal power value of 1,000 Newtons (which corresponds to a body weight of ca. 100kg), after which the force is gradually released. In this way, a ‘banana-shaped’ curve is formed. The smaller the area between the loading and unloading curve, i.e. the more slender the banana curve, the less energy is absorbed by the mattress core and the more energy is released to support the sleeper to change his position in bed. The ‘energy return’ has to be in equilibrium with sufficient damping, so a minimum of hysteresis is required. Innergetic mattresses ensure 25 to 30% less energy loss than most of the standard latex foam cores available on the market today.
