A first blower (13) supplies air through a tube (12) to an inner chamber (7) whose flat shape is defined by perforated partitions (9). Extensions to these partitions (8) are perforated and hold the upper (2) and lower (3) foils of an outer chamber. A second blower (11) supplies air through a tube (10) to an outer chamber at lower pressure. Air may circulate freely between the upper (5) and lower (6) parts of the outer chamber. The top foil has a thin layer (1) which is compatible with human skin. |
