Elasticity

The elasticity also largely contributes to the comfort and it is often expressed as a percentage. To determine the elasticity, a little steel ball is dropped onto the foam and the height it bounces back up to is measured. An elasticity of 70% for example means that during the test, the ball bounces back up to 70% of the starting height. Our Eucabase^®-foams on average achieve an elasticity of 40% to 50%, our Eucaselect^®-foams an elasticity of 50 to 60%.
