Quick help needed! Sienna- Nautilus vs Pioneer vs Prosport, see full thread for all ?


New member
Leaving for vacation tomorrow and realized today that oldest DD has outgrown her Boulevard. Eek. Really wanted a prosport but even with one day shipping from amazon it won't arrive in time and no one local has them! Maybe I'll check swap boards for used one in KC! :) She is pretty good in a booster but we will be driving over 2K miles and I'm not sure I am ready for that! (Boosters on hand are Vivo and Parkway SG)
Her stats: 45.5 inches, 39 lbs

Local in stock choices are Pioneer 70 and Nautilus...I've never owned anything Graco so am hesitant, but it's about $50 cheaper. Cost really isn't a big deal though!
Vehicle is 2014 Sienna. She will need to be in captains chair and 3rd row with belt...I think, not sure on LATCH weight limits on these seats and new van?!

The Pioneer is 40 pound LATCH limit. If it's made since March or so it'll have 19.5" top slots (much taller than the ProSport, which is the old version of the current Performance Sport).

The Nautilus if it's made since 2/27/14 will have a 42 pound LATCH limit. It has 18.5" top slots, so a bit taller than the Pro/Performance Sport as well.

Both of these will harness and booster longer than the Recaro.

You can always install with the seatbelt.

I'd go for one of these over the Recaro anyway, for longevity and ease of installation.
