A support and cushioning structure is disclosed. The support and cushioning structure is capable of supporting and cushioning the ankles in crossed-ankle positions. It includes a lower channel sized and positioned to allow a lower leg to pass through, and a top face with an elongate concave support for the calf of the upper leg and a symmetrical pair of concave ankle rests for the ankle of the upper leg. The support and cushioning structure may be comprised of a block of foam, such as urethane foam, and may be covered by a flexible cover.
