Abstract
Abstract A pillow (1) which may be placed between the knees (22, 26) of a leg (20), so as to prevent chafing between the knees when a person is required to recline on their side for a long period of time. The pillow (1) is generally rectangular in plan form, and includes a series of notches (6, 7, 8) which permit the pillow to deflect in a manner consistent with the movement of the knee. A plurality of straps (14, 17) are used to fasten the pillow to the knee, fastening of the straps being accomplished by means of hookable fasteners (15, 18).
