Thanks for all the good suggestions. I am glad someone suggesting sitting in a Nautilus, because I had him do it today at Target, and you are right about the crotch strap being very far back. My DS was sitting on top of it too. Also, and more importantly, is that the highest shoulder strap level was well below the top of his shoulders, so that definitely rules that one out.
I wish I had a way of trying out the Frontier, but that one I'd have to order online. I think I'm leaning towards that one though.
Can anyone speak to the shoulder straps on that one?
I like the idea of getting one that is convertible to the booster for later. We currently have a Britax Regent in the permanent car, which we are very happy with, and is very roomy, he still has tons of room to grow in that one. We aren't even on the top shoulder strap yet.
But I don't want to get another Regent, because it is so big and bulky and this is one will need to moved around some (not a lot, but I want it to be easy to take in and out). The Regent is actually pretty easy to install and get a good fit, it's just so big and bulky. And I'd rather go ahead and get something that can also serve as a booster a year from now. (If possible, that is, I would be fine with getting another regent if that's what it came to.)
So, can anyone speak to two things on the Frontier:
1) Shoulder strap height option?
2) Ease of install?
