This grow-with-me car seat takes the stress out of moving from stage to stage, while continuously providing a secure and comfy ride for your child.

10 Year Lifespan


  • Rear-Facing: Suitable for children 5 to 40 lbs.or up to to 49" tall
  • Forward Facing: 22 lbs to 65 lbs or up to to 49" tall
  • Seat Dimensions: 20.5" D x 17" W x 23.5" H  
  • Seat Weight: 27.2 lbs.

The Poplar’s versatile design accommodates your child's growth from infancy to toddlerhood.  

In rear-facing mode, this car seat ensures optimal safety up to the 40-pound mark or 49" in height, providing a secure ride for your baby.

Once your child reaches the max height or weight (whatever comes first), you can turn the seat around to forward-facing mode and use up to 65 lbs (or 49"). As your family expands, the Poplar remains a steadfast companion with its impressive 10-year lifespan, enough to see multiple children through their convertible car seat stage. 

The 17-inch seat width, a hallmark of Britax’s SpaceSaver design, aims to fit three across your backseat without compromising safety and comfort. However, individual vehicle configurations may impact the feasibility of 3-across installation, so be sure to check compatibility with your vehicle.

Britax is serious about keeping your precious angel safe! Here’s a closer look at the Poplar’s excellent safety features: 

Durable Frame: The Poplar boasts a robust frame and precisely designed belt paths, providing a foundation of strength and stability for optimal safety. 

Rebound Reduce Stability Bar: A carbon steel bar attaches seamlessly to the car seat for use in rear-facing mode. Its purpose is to minimize movement in the event of a crash, adding an extra layer of protection.  

5-Point Safety Harness: This integral feature ensures crash energy is evenly distributed, enhancing the overall safety of the car seat and keeping your child secure during any unexpected events. 

V-Shaped Tether: Offering two connection points, the V-shaped top tether plays a crucial role in slowing and reducing forward movement in a crash. When not in use, it conveniently stores away, keeping the car seat area clutter-free. 

Naturally Flame-Retardant Fabrics: The Poplar is covered in natural, flame-retardant fabrics, eliminating the need for added FR chemicals while maintaining a high standard of protection. 

SafeCell Technology: Acting as a crumple zone, Britax’s SafeCell technology is a key player in redirecting crash energy away from your babe in the event of a collision.

Indulging in Comfort 

The Poplar comes with a range of convenient and comfortable features that enhance every journey.  

A specially crafted removable infant insert for newborns (under 22 lbs.) ensures proper positioning and support for the tiniest passengers. As a busy parent, you’ll enjoy the easy-adjust harness and headrest. These use a no-rethread design and provide 14 positions for effortless adjustments as your child grows. A flip-forward buckle pad is also included, a strategic timesaver that stays out of the way for zero fuss!  

Embracing the practical side of parenting, the Poplar's covers are washer and dryer-friendly, eliminating the hassle of hand-washing and allowing for quick and easy cleanup. Additionally, the seat comes with two dishwasher-safe cup holders that slide in and out for convenience and a touch of luxury on the go!
