A compressive member is used to bias a seat backrest into a predetermined position, generally upright as illustrated, relative to a seat base with the compressive member deforming to enable the seat to be pivoted by the application of force to the backrest. When used on a materials handling vehicle for which it is particularly applicable, the resiliently biased backrest attenuates forces that are transferred to the back of an operator occupying the seat when the vehicle is driven over irregularities in a floor supporting the vehicle.
