Convertible car seat recommendations [on]

Hello,

We currently have the Clek Liing infant seat and have loved it. Our baby is 6 months old and around 29 inches long, they will be outgrowing height long before weight on this seat. We are looking to upgrade to a convertible car seat. I am torn between the Clek Foonf/Fllo and the Britax Poplar S. We both drive large vehicles so space is not an issue. I am concerned about Clek rear facing height limits being lower than other seats.

Any input appreciated.

Thank you.
