Oooh, new car, new seat funness
I think these are highly likable lately...

Harmony Cruz for the same reasons, low and curvy, but can't LATCH.
Big Kid Amp... might be great, might suck eggs... it makes my DD too tall for her shoulderbelt... that's something to really look at, taller kids get so tall that shoulderbelts start falling sideways off their arms, so 'shorter' seats can be better for taller kids. Cosco Top Side is nice, but the shoulderbelt goes up over the armrest on the buckle side and can make the shoulderbelt go across kids' necks, depending on how high the shoulderbelt is anchored.
Harmony Transit looks neato and it intrigues me, but I haven't had spare cash to buy it to try it lately. Leah thinks the memory foam is super cool though (I think all these seats are at Target and sparsely packaged, if you need to try them in the parking lot and return immediately).
Never an easy answer from me, is it? I'd sure like a booster that you could dial deeper/taller/wider depending on the kid, but who'd pay three hundred bucks for that technology? lol.
