1. A method of selecting a mattress/foundation combination with a minimum motion transfer between subjects positioned on a common mattress surface, comprising the steps of:
- supporting a mattress on a foundation;
positioning an object representative of a first subject on the common mattress surface at a first location;
moving the common mattress surface adjacent to the object;
measuring a displacement of a place on the object relative to a reference location in response to moving the common mattress surface; and
recording the measured displacement for a plurality of mattress/foundation combinations to determine at least one mattress/foundation combination that has the minimum motion transfer.

Abstract
A method and system for analyzing the transfer of motion to a subject on a sleeping surface. A mattress is positioned on a frame, and a subject is positioned on the mattress. A sensor is placed in communication with the subject. The surface adjacent the subject is moved by means of a moving mass, and the sensor detects the motion of the subject. Motion transferred to the subject as a result of the mattress moving is measured and recorded.

8. A method for quantifying a performance of a mattress, comprising:
-
exciting a first motion on a mattress surface at a first location;
providing a stationary surface that is unaffected by any movement;
providing at least one displaceable surface on or above the mattress upper surface at a second location spaced apart from the first location;
detecting a displacement of the at least one displaceable surface relative to the stationary surface that represents a movement transferred from motion at the first location;
comparing the detected displacement with a reference value to quantify the performance. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
