Ready to go with room to grow! The Poplar S convertible car seat takes the stress out of moving to the next car seat stage. This convertible car seat accommodates up to 50 lbs when installed rear-facing and easily switches to a forward-facing car seat as your child grows.

Britax's ClickTight technology makes adjustments and installs smooth and simple. The fully open seat belt paths are clearly labeled and easy to access, and the automatic tensioner takes care of the tightening. Easily adjust the 14-position no-rethread harness and headrest to help create the perfect fit. The removable infant insert helps to properly position infants 22 lbs and under. There are 2 additional premium inserts that help create refined comfort and a tailored fit.

Designed with ultimate safety in mind, the Poplar S features Britax's ReboundReduce™ stability bar. Easily attach it to the car seat when installed rear-facing, helping to minimize movement in the event of a crash. Additionally, the patented SafeCell® crumple zone and a V-shaped top tether help manage crash energy, while the carbon steel frame and belt paths provide strength and stability. The car seat cover fabrics are naturally flame-retardant with no added FR chemicals, and they’re safe to machine wash and dry time and again.

Slim outside and spacious inside, this convertible car seat also features 17-inch SpaceSaver™ technology designed to fit 3-across* without compromising on trusted Britax safety and premium comfort!

CPS Techs

What is a CPS tech?

A CPS tech is a Certified Passenger Safety Technician. Our Cubby Moms who have certified as CPS techs are specially trained on how to properly install car seats and booster seats, ensuring they know everything there is to know about keeping children safe in vehicles.
Through required continuing education courses and hours of personal research and team training, our CPS techs are able to remain up to date on the latest technical information regarding child safety.
Question mark icon

How does a CPS tech get certified?

In order to become certified, each prospective tech must attend The National Child Passenger Safety Certification Training Program. After intensive classroom instruction, they must pass a variety of written tests, demonstrate their knowledge through hands-on skills assessments, and perform safety checks at a check-up event before becoming certified. They learn the ins and outs of car seat installation possibilities, installing car seats in different vehicles, harnessing methods, and more. The car seat and safety industry is constantly changing, so our CPS techs here at The Baby Cubby are an invaluable resource for parents purchasing a new car seat, or for ones who simply want someone to double check that their current car seat is properly installed.
