Britax - Poplar S Convertible Car Seat - Slim 17” Design

We have the Britax poplar with anti rebound bar. I honestly prefer it over our Rava. Britax is also flame retardant free. I’ve had better experiences with their customer service and CPST than with nuna’s. I really dislike how Nuna handled the recall of the Rava. And honestly the fabric isn’t really any nicer than the poplar, nor is the padding. “Safest” is something we don’t really know: all seats must pass the same minimum, but we don’t know what they actually score on various tests because the results aren’t published. So every seat is equally ‘minimally’ safe, and we don’t know which seats exceed that minimum (or in which categories/test subsections). 

I use the Britax one. It's like a luggage cart, folds up, and goes in the overhead bin when we get on the plane. I do use a Britax Poplar since it's narrow, and I can wheel it down the aisle. Previously, we used a one4life (also britax) but had to carry it through the plane since it was so wide (dont recommend)
