Mattress spring test

This test is used to test changes in spring diameter, core diameter and height (mainly changes in spring height.)

The machine is divided into two parts for the spring test. The upper part is used to test the pocket spring and the lower part is used to test the round spring.

Each spring was compressed 200,000 times and then compared to the height of the spring before compression to collect changes in the spring shrinkage test.

The test results usually have a positive or negative 2 cm difference and the spring height typically shrinks and decreases.

The result of the 200,000 spring compression tests proves that our mattress can guarantee a 10-year shelf life.
