A seat assembly for an off-road vehicle includes a seat having a bottom surface, and a resilient seat suspension supporting the seat. The seat is supported at least in part by a first bumper element carried by the seat suspension. The first bumper element includes a protruding portion interposed between the seat bottom surface and the seat suspension, the protruding portion supporting a portion of the seat from the seat suspension. The seat suspension and the first bumper element are arranged to adjust a length of the protruding portion. The length of the protruding portion can be adjusted to set an elevation of the seat at the point of support by the first bumper element. The seat can also be adjustably connected to another part of the resilient seat suspension by use of a seat bracket with selectable holes to register with holes provided on the resilient seat suspension.
