Environmentally conditioned furniture, such as a bed (10), has a permeable mattress (12) or cushion set upon a plenum chamber base (11), with ventilator fan (13), distribution duct (65) and heater (64), co-operatively disposed to intake ambient air and expel conditioned chamber air through the mattress (12) under temperature and so relative humidity control, for comfort and/or respiratory benefit of a bed occupant; a particular construction employs a shallow unitary moulded tray as a plenum module (135) between mattress and base frame, with self contained conditioner unit (140). |
