Careva Shoulder KITThe Careva Shoulder KIT is suitable for persons who require additional support to an upright seated position, as is required for the safety seatbelt to work optimally. An upright seated position also helps keep the lungs in a better position in the chest, stimulating breathing and ventilation. The belt has an easily adjustable padded shoulder strap. The Careva Shoulder KIT can be used with or without a booster seat or a forward facing child car seat.
