ABSTRACT:
A convectively air-ventilated furniture comprises an elongated and hollow member having a lower end with an air inlet opening thereat and an upper end with an air exit opening thereat. A massive and elongated convective air channel extends from the air inlet opening to the air exit opening inside the hollow member. The contact areas between the user of the furniture and the top surface of the member are thermally conductive so that the body heat of the user heats up the air inside the hollow member thereby, through chimney effect, initiating and maintaining in the air channel a convective air current directed from the air inlet opening toward the air exit opening and substantially increasing the rate of heat transfer between the user and the air inside the hollow member.
