The seal portion can have an undulating configuration of at least one peak and at least one valley, and the plate portion can circumferentially surround the seal portion. The seal portion can be made of a first material and the plate portion can be made of a second material more rigid than the first material. The seal portion can have a radially inward facing contact surface that defines a central opening of the sealing.

Abstract: A rocker support insert for a support rocker comprises a support plate configured to be removably coupled to a top portion of a rocker body; and a support padding fixedly coupled to a top surface of the support plate such that a portion of the top surface of the support plate remains exposed. A top surface of the support padding can define a concave upward-facing contact surface, and the support padding can be thicker than the support plate.
