Abstract
A climate controlled seat assembly comprises a chamber defined by a substantially fluid impermeable layer, the fluid impermeable layer having a first side and second side, the first side comprising a plurality of openings, a support structure positioned within the chamber, the support structure being configured to substantially maintain the shape of the chamber, a fluid transfer device configured to provide a volume of fluid to the chamber, a fluid inlet in fluid communication with both the chamber and the fluid transfer device, a fluid distribution layer positioned adjacent to the first side of the fluid impermeable layer and a seat covering positioned along the fluid distribution layer. In some embodiments, the fluid distribution layer is configured to generally distribute fluid from the openings toward the seat covering.
