My son is 4 years old and is about 37lbs.
Thanks for the info but I'm rusty on my IV lingo!!
HBB means high back booster NBB means no back booster. So for one you just take the harness off and its the high back booster and the other the back of the seat comes off and becomes a no back booster. Dawn
Ah! Ok, makes sense! :)
What I have seen of the Rumi is supposedly the top slots are 16.5 inches. That is 2 inches shorter then the Nautilus. Also the cover isn't removable just some bottom pad is. Also it has to be a full recline to have it installed, so that could cause some install issues. I know this is shallow but I just don't like the look of the seat. Also it seems to be the same price as the Graco Nautilus. So I think you got a good price on your 2 seats.
Also a nbb is safe a hbb is a little safer due to the fact it offers some side impact protection and sleep support. I think a nbb is good when your kids are older say 8 or over and they want a seat there friends can't see from out the window. Where I am they just recently passed a law last year saying kids need to be in a booster seat till they turn 8. So when mine where little most kids where out of booster seat by 4 some did till at least 6. My youngest was in a booster till he was 12. He is the only one I have ever seen in a booster that long. Most people looked at me like I had two heads. So nbb have a place for smaller kids who still need a booster seat but don't want there friends to see to make fun of them when they are 8 or over and all there friends are using regular seat belts.
