Ready for the next car seat adventure? The Britax Poplar™ S convertible car seat has your back, making the move stress-free with its patented ClickTight® installation and slim SpaceSaver™ design. No more wrestling with seat belts – ClickTight's got fully open paths and a nifty automatic tensioner for a snug fit. Plus, it's a breeze to switch from rear-facing (up to 50 lbs) to forward-facing as your little one grows. Need the perfect fit? The 14-position no-rethread harness and headrest are your go-to. And for the tiniest ones, there's a removable infant insert that does the job right. The ReboundReduce™ stability bar has your back, minimizing movement when the seat's rear-facing. Even though it's slim on the outside, inside is a 17-inch SpaceSaver™ tech, letting you potentially fit 3-across* without skimping on Britax safety. Carbon steel frame and belt paths mean it's solid as a rock. And hey, safety meets style – the fabrics are naturally flame-retardant, and you can toss them in the wash stress-free.  *Britax cannot guarantee 3-across installation fitment in all vehicles
