The Mattress Compression Tester evaluates a degree of firmness common within the mattress and foam industries. Alos, either in the laboratory, or on the production line.

This universal measurement of firmness and hardness is based on a physical property. Which is the indentation force deflection (IFD). And is 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 useful for moulded shapes.

Software Package

The Mattress Compression Tester offers a variety of software features. Thus, allows programming of parameters, operational control and real-time display of the on-going test. This software package allows the operator to conduct a wide range of tests with an almost limitless array of test parameters and displayed test information when used with a compatible PC. The PC based control system uses the Universal Tester program developed by IDM Instruments Pty Ltd.

The Test Configuration is separate for each test sample type. This procedure is fully automatic. To run a test, enter test scripts and the operating parameters in the Configuration Panel. Values including the test type, sample piece, sample size, standard reference. And allows entering and saving many more values. It also allows retrieval of these at a later stage.

The Software Program for the Mattress Compression Tester is automatic. Once the Test Configuration menu has been programmed which is pressing the “Start” button. This initiates the test. The PC displays results in real time. It saves these for printing or for later use. So, they can then be used in the future.
