Highback Booster Seat W/5 Point Harness for Tall Kids? What Do You Use?

We have the Sunshine Kids (Now Diono) 5pt carseat that we use for our 4.5 year old that is close in size to a 6 year old. It's a fantastic seat with high safety ratings. It's also got a narrow base so it fits well in most cars. It's convertible to a booster when the time comes to switch her to that. It attaches using LATCH when being used as a booster so it does not become a projectile in the event of an accident.

I am a bit concerned when you mention leaving your child's coat on in a car seat. Please tell me you do not mean a large winter coat! It is dangerous to buckle a child in their seat with a bulky/puffy coat on. Please read the information in the following link about the safety of leaving a child in their coats while buckled in their seats.

#1 - no coats when buckled into the car seat.

I just moved my almost 5 year old into the Pinnacle 90, love it!

Edited: you really can't go wrong with britax... we have the sunshine radian(now diono) in my husband's car bc all three were in car seats for a short time and that was all that fit three across... it's a good seat and a safe seat, but the padding and comfort is inferior to britax, especially if that's what your child is used to. I'd avoid Graco/Cosco and the like at all costs - good luck :)

My 6 year old is in the Britax Frontier in one car and the Graco Nautilus in the other. He has plenty of room to grow in each and he's already about 49" and 53 lbs. He prefers the Britax for comfort but the Graco is less expensive and easier to install. If you can afford the Britax and don't need to move it frequently, I think it is definitely worth the extra money. Otherwise, my son is also happy in the Graco.

Both seats convert to both a high back and backless booster over time.

LOVE our Graco Nautilus. We just moved my son (he was 7 at the time) from the 5 point harness to the high back booster. It is a 3 in 1 seat that works as either a high or low back booster up to 100 lbs and as a car seat w 5 point restraint up to 65 lbs.

We have the Britax Frontier 85. It does cost a lot, but as my hubby pointed out, she is in my car, a lot! She is now 7y, weighs 47 lbs, and doesn't mind using it, because she picked the color. Before we had the Britax Marathon with a purple floral pattern, that 'was babyish'. I didn't think so, but ...

I found ours on Amazon, on a really good sale. It was around $200, saving 80+, with free shipping. It arrived at our door 2 days later. Yeah!

We have the graco Nautilus. Love it. Just put my 5 year old in with out the 5 point this winter.

I am watching the sales, and will be moving my daughter to it soon.
