The first chamber is seated over the second chamber to form a gas filled cell between the walls of the enclosed portion of the first chamber and the walls of the second chamber. Preferably, a plurality of ribs project from the walls of the second chamber into the gas filled cell to form a plurality of gas filled pockets between the ribs, and the walls of the enclosed portion of the first chamber and the second chamber.
