Britax Advocate G4 Convertible Car Seat - Onyx
[Download an Information Sheet. Click here. Please note that this feature may not be supported on mobile platforms.]

The Britax Advocate convertible car seat achieves revolutionary head safety through the use of Britax SafeCell Technology in the base and HUGS chest pads, integrated steel bars, and energy absorbing Versa-Tether that work together to minimize head excursion and reduce the risk of head injury during a frontal impact. The Pavilion is equipped with Britax True Side Impact Protection and a Click & Safe Snug Harness Indicator to aid in proper harness snugness. Additional features include a no-rethread and quick-adjust five-point harness, multiple buckle and recline adjustments, and an easy-remove cover that also allows access to belt paths from the front of the seat. An infant pillow is provided for extra comfort and infant positioning.


  • HUGS Chest Pads with SafeCell Technology are affixed to the seat shell to ensure proper positioning while SafeCells compress to manage energy and provide resistance to the forward movement of your child in a crash
  • EZ-Buckle System retains the harness buckle in a forward position and prevents the child from sitting on the buckle when boarding
  • True Side Impact Protection a head restraint which offers a double layer of EPP foam to distribute crash forces, shield from vehicle intrusion, and contain the head, neck and body
  • Base with SafeCell Technology compress in a crash, significantly lowering the center of gravity and counteracting the forward rotation of the child seat which normally propels the child toward the front seat
  • Integrated Steel Bars strengthen the connection to the vehicle and reduce forward flexing of the child seat during a crash
  • Energy-Absorbing Versa-Tether features a staged-release tether webbing to slow the forward movement, reducing the crash forces reaching the child, and a two-point attachment to minimize forward rotation while anchoring the top of the child seat
  • Side Impact Cushion Technology features energy-absorbing cushions on the exterior of the child seat to reduce side impact crash energy by 45% by diverting crash forces away from your child and providing extra protection for the adjacent passenger
  • Click & Safe Snug Harness Indicator is an audible aid that provides extra assurance when the harness is within range of appropriate snugness
  • Premium Lower LATCH Connectors for a quick and simple installation featuring a push button for easy release
  • Certified for Aircraft Travel

    I can't say enough about this car seat. I purchased this to replace the Marathon that was my son's and was purchased in 2008. After researching car seats, since the Marathon was to expire this year, I found the Advocate. The safety features are top notch. I am loyal to the Britax brand and had to have this. It is everything I wanted it to be and more. The fabric is gorgeous and the seat is so plush. My daughter who will be 2 next month loves it.
