A therapeutic cushion (1) having a plurality of fluid-filled chambers (2, 3, 4, 5, 6), with each chamber having an internal volume that is independently adjustable. In a pillow embodiment, air-filled chambers are dynamically regulated in response to a monitored behavior or characteristic of a resting user. Air cushion (1) includes a lower chamber (2) upon which the other chambers are arranged. First or basic chamber (3) extends laterally along, and is directed inwardly from, a rear edge of underlying chamber (2). Adjoining first chamber (3) are first and second supporting chambers (4, 5), these being separated from one another to leave a region (10) that is disposed between their ends (7, 8) and bisected by center line (9). Region (10) is intended to accommodate the resting users head. A second lateral chamber (6) extends laterally along and is directed inwardly from a forward edge of underlying chamber (2) to adjoin supporting chambers (4, 5), providing a neck support. To configure the cushion (1) to provide a therapeutic treatment for snoring, at least one sensor is included to detect and monitor snoring intensity and thereby provide feedback to the dynamic pressure regulation process.
