EFFORTLESS MASSAGE The Beaded Seat Cushion is designed to give you an effortless and gentle back and thigh massage with ventilation while you are seated in your car seat, office chair, or for home use. SWEAT CONTROL - It is a very useful product as it prevents sweat by maintaining air circulation in between the marble beads. Marble beads always remain cool no matter how much is the temperature and make the drive very comfortable. The driver can sit easily on the car seat without any problem even if the car is parked in hot condition for long hours.
