OK, so this is certainly bumping an old thread, but it's exactly what I'm working on right now, so I'm wondering if there have been any updates to this. I'm planning on doing a YouTube video comparing the MT to the Radian soon, but now I'm trying to sort out the true RF limits of the Foonf as well.
I have two Multi-Techs, and the limiting factor for height is actually 15.25" torso height (25" top of headrest in highest slot and child's eyes level with top of seat).
For the Radian I was figuring 23.5" seated height since the shell is 25", however maybe I can bump that to 24" based on the last post.
When I look at the measurements for the Foonf, it looks like it should be good to 25" seated height since the top headrest height is 26" - 1" = 25"
My question is, what's the deal with the stated 43" standing height limit for RF (44" stated for Radian)??? I just measured my daughter who's just under 50lbs and is 47" tall and her seated height is only 25.25", so she would have just barely outgrown the Foonf RF for the 1" below limit, but would have outgrown it over a year ago based on the 43" standing height limit! An extra year of RFing is huge, and a lot to give up for what seems to be an arbitrary standing height limit.
So, what's the deal? Anybody have any clarification on this? (I'm also bumping this thread back up because I just saw we have the Clek CPST on the forum now, so I'd love to get her input!)
