A vehicle seat has a seat bottom and seat back. The seat bottom can have a ventilated insert located between the seat upholstery and the seat cushion. The insert can be in fluid communication with the cabin space of the vehicle. In one arrangement, the insert has a cover with holes and a body. The cover and body cooperate to form a plurality of plenums for passing air through the insert. A fluid system can deliver air to the insert so that the air passes through the plenums and directed out of the holes in the cover. The air then flows out of the vehicle seat to control the climate around the person in the seat. The insert can also be used to remove air near the seat by drawing air proximate the seat into the insert. The air can then pass through the insert and is delivered to the fluid system.
