The i-Traver is Joie’s newest i-Size (R129/03) high backed booster which is suitable from 100 to 150cm (approximately 4 to 12 years). The Tri-Protect headrest offers three layers of protection while the Guard Surround Safety panels add extra side impact protection. Adjustable ISOFIX connectors allow for a secure installation that will give you peace of mind, but it can also be installed simply using a 3 point seat belt if necessary. The 10-position headrest allows all children to comfortably fit this seat while the 3-position Auto Adjust seat depth is great for those growing legs.
