We use this instrument to repeatedly compress the sponge to test the hardness, elasticity and comfort of the mattress.
The test machine was used, and the 3 guns were respectively pressed down to 25%, 40% and 65% of the original thickness to obtain an index of comfort (compression ratio = 65%/25%). This unit is regarded as "N".
