Abstract: To assist in complying with strict Federal standards of cleanliness for industrial clean rooms, a sealed upholstered seat is placed in communication with an underlying relatively shallow breather bag which is retained by a seat pan attached to a rigid panel of the seat. The breather bag receives air from the upholstered seat when the seat is compressed and returns the same air to the seat as the seat expands. The escape of particulate matter from the seat into the atmosphere during usage of the seat is eliminated. A seat standard is received through an opening in the pan and passes between two spaced portions of the breather bag. The top of the standard is welded between the side walls of a channel member having side flanges which are attached to the bottom of the seat panel.
