Seat Cushions Available here. Anyone who has spent long spells in traffic knows the discomfort of spending hours in the car. Remaining in one position for so long can cause fatigue, neck stiffness and back pain. Fortunately, drivers can choose from car seat cushions that provide support and ease the strain on their muscles. We offer inflatable and foam products that provide neck relief, lumbar cushioning and full back support. Our seat cushions include features such as belts to prevent shifting, and washable or removable covers for durability. We can help you choose the seat cushion you need to enhance your comfort, whether you are a casual driver or a road warrior.
