Patented V-shaped tether minimizes seat rotation with a unique two-strap design and staged-release stitches that slow and reduce forward movement during a crash.
Quick-adjust 12-position harness and 2-position buckle allows you to easily move the harness upward and buckle outward for a comfortable secure fit as your child grows.
7-position recline with automatic level indicator adjusts for your child’s comfort while ensuring the best installation angle for your vehicle.
Plush foam padding and fabrics for premium comfort.
Easy-buckle system keeps buckles and straps out of your way when positioning your child.
