Compression testing device F0024

for mattressesuniversal

The Mattress Compression Tester is used to evaluate a degree of firmness common within the mattress and foam industries, either in the laboratory, or on the production line. This universal measurement of firmness and hardness is based on a physical property called the indentation force deflection (IFD) and is calculated by determining the force required to deflect the test piece a percentage of its original thickness using a circular indentor. The circular indentor foot applies a force, while also recording the degree of indentation. To compare test results, test pieces must be of the same size and thickness. The whole article may be used if moulded shapes are being tested.
