The Britax Allegiance is safe and comfy for your little one while you’re on the go. Britax SafeCell Impact Protection is a system of patented safety features that provide advanced protection. A foam-lined shell provides side impact protection in the event of a crash.

Specifications

• ClickTight Installation System is safe and simple to use. Open the front of the car seat, feed the seatbelt through the indicated path, buckle and click the seat shut.
• 3 layers of side impact protection, formed by a deep energy-absorbing shell, quick-adjust head protection and side cushions, absorb energy and shield your child from the most severe type of collision.
• SafeCell Impact Protection includes a steel frame, energy-absorbing base and patented V-shaped tether.
• Impact-absorbing base compresses to reduce the force of a collision.
• Impact-stabilizing steel frame offers superior strength where you need it most: at the connection point to the vehicle.
• 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.
• Click & Safe Snug Harness Indicator gives an audible “click” to aid you in the proper tightening of your child’s harness.
• Quick-adjust 14-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 proper recline rear-facing or for comfort and the best vehicle fit forward-facing.
• Plush foam padding and fabrics for premium comfort.
• Easy-buckle system keeps buckles and straps out of your way when positioning your child.
• Easy-remove cover for cleaning without having to uninstall the car seat or remove the harness.
• Suitable for children 5-65 lbs.
  
• 1-Year Limited Warranty.
