Patent number: 7124652Abstract: A method for selecting a sleep system comprises positioning a person on a mattress in a lying position. One of the person's arms extends generally perpendicular to the person's torso. A first pillow is positioned underneath the person's head, and a force is applied to the person's arm in a direction generally toward the person's feet. An amount of resistive force supplied by the person's arm is estimated and used to determine whether the proper combination of mattress and pillow is achieved.Type: GrantFiled: December 5, 2005Date of Patent: October 24, 2006Assignee: Denver Mattress Co., LLCInventor: Larry W.
