Both the Body Support Cushion and Headrest MUST be used with children who are under 11 lb AND whose shoulders are below the lowest shoulder harness slots.
For children weighing more than 11 lb, the Body Support Cushion can continue to be used until the child’s shoulders reach the top shoulder harness slot, which at that point it MUST be removed. The Headrest may be used until the child outgrows the seat.
