ABSTRACT:
An improvement to a seat having relatively adjustable sections to improve the rocking means of each separate seat section to move back and forth in a longitudinal rocking, move downwardly and sliding backwardly, to thereby more effectively and efficiently assist in the comfort of the individual. The improvement includes a seat rocking member such as an arch shaped suspension affixed to the lower portion of each seat half and affixed at only one side to the upper surface of the base. The resilience of the arch shaped suspensions permits and limits the seat to move downwardly and slide backwardly, when a force such as the weight of a person pushes downwardly on the seat. The resilience of the arch shaped suspensions further permits and limits the seat to rock back and forth to thereby enable the user to independently rock back and forth in a front to back rocking arrangement on each seat half.
