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. Plus, installation is easy using lower anchors that lock into place with a click and are released with the push of a button.

 

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.

Good
Color: Grey
Works as it should, but one of the brackets on the leg broke while setting up. Super glue is holding it in just fine.

Not good for putting away daily
Color: Grey
This product may work of you are doing a full install, but is terrible for putting up and taking down daily. I have only had it 2 months and it is falling apart and will not stand straight.

Privacy at ease!
Color: Black, Color: Black
This is exactly what we needed for our large house and bedroom sharing with the kids. People need privacy and this can be tucked away when it isn't being used. Perfect!
