Abstract

A system for measuring or testing the firmness of a resilient object such as a mattress. A pressure applying platen or the like is driven by a motor into the object, and the pressure applied is measured through the utilization of a pressure sensitive transducer or the like. This generates electrical power proportional to the pressure, and a recorder displays information to provide a reading of the power generated. The generating means is also connected to control means for the motor, and a threshold circuit or the like is adapted to shut off and reverse the motor when the power generated reaches a predetermined level.
