The Poplar S convertible car seat streamlines the transition to the next stage with its ClickTight installation and SpaceSaver design. Accommodating up to 50 lbs in rear-facing mode, it easily converts to forward-facing as your child grows. ClickTight technology ensures straightforward seat belt paths, while a 14-position no-rethread harness allows for easy adjustments. Additional padding for your children's head and an anti-rebound bar are both included, because safety and comfort are top priority Despite its slim exterior, the 17-inch SpaceSaver technology provides a spacious interior, fitting 3-across* without compromising safety. Features include a SafeCell crumple zone, a V-shaped top tether, and a robust carbon steel frame. The flame-retardant, machine-washable car seat cover ensures safety and convenience.

Disclaimer: Britax cannot guarantee 3-across installation fitment in all vehicles.


What is the difference between Poplar and Poplar S car seats?  The enhanced Poplar S version includes an anti-rebound bar for added protection when rear-facing and added padding at the headrest.
