Suitable for rearward-facing travel from 40 to 80cm (birth to approx. 15 months), the egg Shell (i-Size) car seat features an enhanced side-impact protection shell, as well as a memory foam headrest providing optimum cushioning for the baby in the event of a collision. In addition, the egg Shell has enhanced inner-body padding (for use from newborn), which provides key support for both the side and upper leg muscles on car journeys. As their muscles strengthen, develop and grow, these key protective cushions can be removed enabling the baby to use the seat up to 13kg.
