Thank you for viewing. The "Form Fit ISOFIX 360° Safety" is an ISOFIX-mounted child and junior seat that can be used from around 1 year old to around 10 years old ※2. It complies with the new safety regulation R129 ※1. It meets the latest regulations and further protects your child. It has 3-stage reclining. The seat also extends as the child grows, and can be used as a junior seat. Official website: https://www.aprica.jp/products/discontinued/detail/childseat/formfit_isofix_360_safety/ Purchased at Akachan Honpo and used by my child from 1 to 6 years old. The covers for the pillow, backrest, and seat can all be removed and washed, so I think it can be used cleanly. We appreciate your consideration, understanding that this is a used item. Thank you.
