The Vario Create's blow moulded design results in enhanced side impact protection, the headrest side wings acting like airbags, greatly reducing the forces on your child's head in a side impact accident. The Vario Create features an Anti-Submarining feature which helps prevent children from serious abdominal injuries caused by the belt lifting and the child sliding under the lap belt in an impact. This is achieved by the arm-rest's unique design which hold's the lap belt firm and secure across the child's lap. The Vario Create outperforms most other booster seats in Anti-Submarining tests performed by CREP, without the use of additional crotch clips. The Vario Create also features an extendable headrest with integrated sash guides, allowing it to grow with your child and maintain a correct fit. It also includes a comfortable, removable cover, a large seat base to accommodate larger children, a narrow external width for 3 across the back installs and comes with a free SafeGrip Belt Clamp for extra piece of mind.
