A padded seating cushion having a main section at the front end and a pair of arms extending rearwardly therefrom to define a generally U-shaped aperture open and extending to the rear of the cushion to support the user's ischial portions while alleviating direct pressure on the coccyx. The arms define an inner section having inner side walls defining a thermal transfer chamber in which a thermal transfer unit is placed to selectively provide heat or cold for the user. The thermal transfer unit attaches to a lower chamber member that attaches to the arms. The thermal transfer unit comprises a thermal unit disposed in a thermal container, preferably in the form of a pouch. The cushion attaches to a seat with removably attached straps connected to ring members on each side of the cushion, providing a padded surface that does not shift with the movements of the user.
