[0003] According to industry standards, soft furniture mattresses need to undergo durability tests to simulate the anti-fatigue capabilities of soft furniture during normal and abnormal use. Existing testing machines use compressed air as a power source, and use the piston rod of the cylinder to push up the impact head. Based on the drop height determined by the compressibility measured before the test, the impact head is used to drop freely at the same frequency on the specified part of the mattress, and the specified number of loadings is repeated.

[0004] However, there are some problems with the existing technology:
