Product details
The Britax Poplar S Convertible Car Seat in Onyx colour takes the stress out of moving to the next car seat stage thanks to the patented ClickTight® Installation and slim SpaceSaver™ design.
This car seat accommodates up to 22.7 kilograms rear facing to help keep your child riding safely even longer and easily switches to a forward facing car seat as your child grows.
ClickTight Technology installation provides fully open seat belt paths that are clearly labelled and easy to access, and the automatic tensioner takes care of the tightening. Slim outside and spacious inside, the toddler car seat features 17" SpaceSaver™ technology designed to fit 3-across* without compromising on trusted Britax safety and premium comfort.
The Britax car seat boasts a patented SafeCell® crumple zone and V-shaped top tether to help manage crash energy. The reinforced frame and belt paths provide strength and stability. Rear facing car seat cover fabrics are naturally flame retardant with no added FR chemicals and safe to machine wash and dry.

Why parents choose the Poplar S
- Anti-rebound bar included: reduces rebound movement in a rear-facing crash, so you don't need to buy it separately.
- ClickTight installation: open the seat, run the seatbelt through the clearly marked path and click it shut. The automatic tensioner takes care of the tightening.
- Rear-facing for longer: suits babies from 2.3kg rear-facing up to 22.6kg, then forward-facing up to 29.4kg.
- Slim 43cm SpaceSaver design: fits three across in most vehicles. Britax can't guarantee this for every car, so check yours.
- SafeCell impact protection: a steel frame, an energy-absorbing base and a V-shaped tether help manage crash forces, with two layers of side impact protection.
- Grows with your child: a no-rethread 14-position harness and headrest, a 2-position buckle and a 6-position recline with a level indicator.
- Easy to clean: the cover comes off without removing the harness and is machine washable. The fabrics are naturally flame-retardant with no added chemicals.
