C-curve shape for baby's peace of mind. A child seat that can also be used as a baby chair, bouncer, and carrier, compatible with travel systems. Joie's child seat is suitable for babies from newborns to 18 months old, with a height of 40cm to 85cm and a weight of 2.5kg to 13kg. - Brand: joie - Color: Black - Size: Suitable for heights 40cm-85cm - Weight Limit: 2.5kg to 13kg - Usage Period: Under 18 months I used it until around one month old. I stopped using it soon after because I started using my older child's child seat. It can be secured in the car with just the seat belt, or it can be placed on a base. It can also be placed on a joie stroller with a travel system, and it's very comfortable to carry the baby while they are sleeping. Thank you for looking.
