Test principle: The body turns over 30 to 40 times a night while sleeping.

The rolling pressure test of the mattress is achieved through 30,000 times of rolling is equivalent to the hardness change test of the mattress for 5 years.

Experimental conclusion: After 30,000 times of rolling and 35 hours of testing, the hardness of the mattress will change.

If the hardness value changes, the mattress generally become soft. We will use this machine to provide test reports, analyze the change of hardness before and after rolling, take the average, and finally get the mattress hardness test results.
