LO1 is almost 3 and moving into a 5pt harness forward facing seat so LO2 can use the convertibles. She's had the Chicco Key fit, the Nextfit and we got the Graco Argos 65 based on Lucie's List.

I thought it was hard to tighten the straps on the Nextfit but the Argos is way worse. If it isn't impossible to do while DD is in her seat it might as well be because we tried everything and cannot make it budge. We're returning them.

Are non-rethread seats generally way harder to tighten than those seats where you have to remove to adjust height occasionally? What seats have easy to adjust straps?
