A vehicle seating assembly comprises a seat having a plurality of air chambers disposed between a seat support and an elastomeric foam layer. The air chambers further comprise a primary chamber in fluid communication with a main chamber, and a secondary chamber in fluid communication with a supplemental chamber, wherein air is displaced from the main chamber to the primary chamber and air is displaced from the secondary chamber to the supplemental chamber when the lower seat is in a loaded condition. Air is displaced from the primary chamber to the main chamber and air is displaced from the supplemental chamber to the secondary chamber when the lower seat is in an unloaded condition.
