Abstract
A device for supporting one's thighs, knees, calves, and feet to obtain relief and comfort from low back pain. The device permits the user to be placed in the correct position to strengthen the stomach muscles without risking injury to the back. When a prone user disposes his thighs at a 32 degree angle to the vertical, the lower spine is partially flattened and the lower back muscle tension is reduced. The curved areas of the support under the knees and heels, and in the same horizontal plane, provide a comfortable transition from the thigh supporting surfaces to the calf and foot supporting areas. The horizontal surface is depressed intermediate to its length and creates a final subtle incline to receive the calf muscles. The unit is customized to the user's leg length measurements.
