Claim:
A method for selecting a mattress from a group of mattresses, the method comprising: positioning a person on a first mattress in a lying position, with one of the person's arms extending generally perpendicular to the person's torso; applying a force to the person's arm in a direction generally toward the person's feet; estimating an amount of resistance to the force supplied by the person's arm. positioning the person on a second mattress in a lying position, with one of the person's arms extending generally perpendicular to the person's torso; applying a force to the person's arm in a direction generally toward the persons feet; estimating an amount of resistance to the force supplied by the person's arm; comparing the amount of resistance produced when lying on the first mattress with the amount of resistance produced when lying on the second mattress to determine which of the resistances were the greatest; and selecting the mattress that is associated with the greatest resistance.
