Sponge rebound test

The comfort of the mattress is related to the rebound rate of the mattress.

Taking a mattress sample (10cm * 10cm * 15cm) as an example, three steel balls are issued on the magnet assembly above the transparent tube with a weight of 16.3g and an inner diameter of 30mm-65mm respectively to measure the rebound height (h) of the ball. The height from the top of the ball to the surface of the sponge is 460 mm, so the rebound value is considered to be R = h/H, and % is its unit.

The tester will automatically calculate an accurate value based on the average of the five values of each of the three balls.
