Abstract: Disclosed is an orthopedic saddle seat cushion, and method for cushioning, to prevent the coccyx of a rider from touching the saddle, to prevent or eliminate lower back discomfort or injury. The cushion allows a substantial area of the rest of the buttocks-seat of the rider to contact the saddle which permits the rider to feel the saddle and thus maintain good control of the animal being ridden. The saddle seat cushion is a circularly shaped outer ring of material that contains a mechanism for inflating the ring, which comprises an inflation tube for putting a gas, or any combination of gases, such as normal air, into the ring to inflate the ring, and an air plug for retaining gas in the ring. There is a fastening mechanism to secure the cushion to the saddle.
