Abstract
The present invention is a device to measure the parallel shear force on a mattress. The device has a motor, a weighted object, a high friction material pad, and a load cell. The motor moves by pushing and pulling the weighted object on the high friction material pad which is on the mattress. The load cell measures the peak shear force when the weighted object is pulled and when the weighted object is pushed.
