The Cornell test represents the human posterior and applies a 230 lbs. load, 100,000 times to the mattress surface in a cyclic pounding format, simulating everything from sitting in bed, reading a book to the occasional “trampoline” use. Firmness and thickness measurements are obtained to assess the amount of change that is brought on by the testing.
The motion transfer test is used to capture the effect that movement on one side of a mattress has on the adjacent side. The point elasticity test is used to measure how well the surface of a mattress adapts to the irregular shape of the body.
