Help picking car seat for almost year old

[Shannie77]

My DD will be 4 in May and we are starting to look for a new car seat for her.  She is 31 pounds and 37 inches right now.  We have her forward facing because we can not get a second car seat in our car rear facing, and drive safely.  I want to get her something that will last as long as possible and something that is easy to instal.  We have an Eddie Bauer 5 in 1 and I HATE it.  It is really hard to install, in doesn't help that our OLD jetta's latch bars are buried between the seats.  

I am so confused as to what is the best choice.  I thought there would be a lot of forward facing/ booster seat options, but most seem to be convertables.  Nothing against convertibles but I just figured we would be paying for something we don't need and something that is strictly forward facing would have a taller shell?!

I was looking at the britax frontier... it seems like a good option but it doesn't look very comfortable.  We drive a fair amount and DD often sleeps in the car.  Something like the True Fit looks comfortable but I can't tell how long it might last?  She sat in a Nautilus today and really liked it... it did look really comfy!  While DD is quite short right now my husband and I are tall so it is possible she might have a growth spurt.

Any suggestions would be most appreciated.  And I suppose I should've mentioned we live in Canada.

The Frontier and Nautilus are your best bets for never having to buy her another seat.  Both make good boosters.

Most kids who ride in Frontiers find them to be comfortable.

As as pp said, both the Nautilus or the Frontier would be fine choices for your dd, but if you liked the Nautilus, Babies r Us Canada has the "Galaxy" pattern (grey) of the Nautilus on sale for 179.99 right now, which is considerabley less than the Frontier.
