Graco MyRide 65's DO NOT turn into a belt positioning booster at all. That seat is strictly a convertible RF/FF harness seat. I hope you pass that information onto whoever informed you of that.
Please read the OP more closely. The poster was told that they do not turn into BPB and is therefore looking for suggestions.
Infants seat usually cost $125-$200 and are usually outgrown before the first or sometimes second birthday.
The MyRide at $125 could keep them rear facing for a long time and will harness them forward facing until about 5, maybe 6 depending on their size.
The booster will fit from 5 or 6 years old to possibly 10+ when they fit in the adult seat belt. So even while boosters seem overpriced, for under $100 you often use them for a few years longer than your other other car seats.
That breakdown sometimes takes the sting out of car seat prices but I can't imagine thinking anything is a good price when buying 4!
I think MyRides would be very cost effective. :thumbsup:
Is one car rarely used? I would consider other, less expensive seats for the 2nd car depending on their
height, weight & age.
Regarding convertible seats that turn into boosters. Many models are notorious for positioning the
seatbelt dangerously. It sounds (from your OP) that the booster seat is years off so it wouldn't even be on my radar yet. Especially when new seats are constantly being developed and released.
