An improved self-leveling seat assembly for tractors and the like having a seat member, a support member, means such as rollers and arcuate track guides securing the seat to the support and providing limited movement of the seat relative to the support along an arc of a circle in response to angularity of the support member relative to angularity of the support member relative to the horizontal, and a piston and cylinder combination secured to the seat member and to the support member for purposes of dampening movement of the seat relative to the support.
