The Cornell type tester is designed to simulate human hip impact on spring mattresses to evaluate fatigue life performance. Using a bottom round block to impact the mattress surface and case spring unit, this equipment provides repeatable, controllable, and countable impacts to assess durability and support strength capabilities. The system measures mattress and case spring unit transformation through surface slots, enabling comprehensive evaluation of mattress durability and spring retention through repeated impact testing.
