The Britax Boulevard convertible car seat is designed for children rear facing from 5 to 40 pounds and forward facing from 20 to 65 pounds. The Boulevard 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 Boulevard also incorporates Britax True Side Impact Protection and offers 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.


  • Quick-Adjust Harness repositions the harness shoulder height without disassembling the harness straps
  • HUGS with SafeCell Technology manages crash energy and forward head movement while keeping the chest clip properly positioned

  • 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
