The two independently operating shock-absorbing pedestals are designed to function properly even when two occupants of different weights are seated. For benches over 48” or heavy-duty applications, three pedestals are recommended. Posts are sold separately or in combination with a custom seat made to the desired seat length, width, color, and type of material. Please consult the factory for your special applications. We recommend flat-sided bases for the outside bench posts to minimize the total footprint. Flat-sided bases measure 9-¼” fore and aft and 6” in width.
