Abstract: An apparatus is described for use in dampening impact loading transmitted between a cycle frame and a cycle seat. The cycle seat support apparatus has: an elongated sleeve attachable at one end to the cycle frame and having an opening extending into the sleeve at the opposite end; an elongated post attachable to the cycle seat at one end and the opposite end being slidably positioned in the opening of the sleeve; and structure for biasing the post to urge the post toward an at rest position when the post is moved relative to the sleeve. The opening in the sleeve has an inner surface and the post has an outer surface which are in sliding engagement during relative sliding movement of the post and the sleeve. The outer surface of the post and the inner surface of the sleeve being made of compatible plastics exhibiting sufficient lubricity to permit sliding movement of the post relative to the sleeve thereby minimizing wear of the inner surface of the sleeve and the outer surface of the post.
