The ComforTrac cervical home traction unit has been carefully engineered to provide maximum comfort, efficacy, and ease of use. Details that highlight this superior design include a push-of-a-button "quick release" pump, and a contouring memory foam headrest that cradles the head. Likewise, transporting the unit has been made effortless through the use of lightweight durable materials and a carry-case with smooth rolling in-line skate wheels and a retractable stow-away handle typically found only in top-quality ballistic luggage.
