Britax Poplar S ClickTight Convertible Car Seat

The Britax Poplar S ClickTight® Convertible Car Seat makes moving to the next car seat stage easier with patented ClickTight® Installation and a slim SpaceSaver™ design.

Suitable for rear-facing use from 2.3kg up to 22.7kg (50lb), the Poplar S helps keep your child rear-facing for longer. Infant inserts are included for a snug, supportive fit from newborn. As your child grows, it converts to a forward-facing car seat for use up to 29.5kg (65lb).

ClickTight® Installation features clearly labelled, easy-to-access seatbelt paths and an automatic tensioner for a secure installation. At just 43cm wide, the SpaceSaver™ design maximises space in your vehicle while providing premium comfort and trusted Britax safety.

The Poplar S features SafeCell® technology, a reinforced carbon steel frame and a patented V-shaped tether to help manage crash forces. Its SafeWash® fabrics are naturally flame-retardant without added flame-retardant chemicals and are machine washable and dryer friendly.
