We've got a Brio Zento, when DD was born, the only carseat in NZ that rf past 12 kg (26.5 lb)! Unfortunately, she is now 3, and 5 cm (2 inches) from the top of the shell.
So we're hoping to sell the Brio Zento, and looking at the Radian. We tried DD in it today, and tried it in the car at the shop. There aren't really any car seat techs here, just sales people, and they know very little about car seats. So it seems the top slots are quite a bit higher than the top slots on the Brio Zento. And I think the shell is about 7 cm taller (not counting the insert thingy on top - the salesperson told us that that can be extended and it counts to the top of that - is that really correct?). DD wasn't really cooperating, so it was hard to see how much shell was left above her head exactly, but it seemed to be at least twice as much in the Brio, possibly three times as much, not counting the thingy on top.
The Brio Zento's shell is 22.5 inches, The Radian 25 inches. DD is only barely 95 cm (95 cm=37.4 inches), and very much proportional. (Brio Zento is supposed to last 'til about 110 cm, I know it doesn't really matter, but t matters in comparison with the Radian, which is supposed to last 'til about 125 cm).
So with a child who is slightly below average height, for a girl, and very proportional, but at below 95 cm has grown out of the Brio Zento, how long might the Radian work for us? DD has followed her curve, just below the 50th percentile, since she was 6 months old, by the way.
Also, the salesperson told us that once DD has grown out of the Radian, we can turn it forward and use it as a booster, and then it doesn't matter if she is taller than the shell. Is this true?
Would be grateful for any help!
