ABSTRACT:
An improved split suspension seat cushion maintains the differing elevation response of a conventional split suspension seat to unequal loading, while evening out the differing reactive upward forces that occur between sides of a conventional split suspension. The left and right suspension mats of the embodiment disclosed, which stretch in response to loading to create an upward reactive forced, are joined to one another at the back through a short sliding cable. In response to an imbalance in a previously balanced and even loading, one side is able to sink down without significantly increasing its stretch, while the other side is able to rise up without significantly decreasing its stretch, thereby maintaining an even loading side to side.
