It can be securely fixed with ISOFIX compatibility. The tether belt system allows for space at the feet and is convenient when sliding the seat. Used from the newborn period to about 2 years and 3 months. Please check the condition in the images as there are small frays, scratches on the cover, and peeling of the adhesive. Also, although I didn't notice it during use, something seems to be inside the cavity, and it makes a rattling sound when tilted. Please refrain from purchasing if you are concerned. Also, please understand that this is an item used by a child before purchasing. Shipping will be packed with bubble wrap. Please understand. - Brand: Nihon Ikuji Nosette - Color: Black/White - Mounting Type: ISOFIX - Modes: Baby Mode, Child Mode, Junior Mode, 360° Rotation, TOP Tether Belt
