outgrown turbobooster?


New member
I am curious-
when did your child outgrow their Turbobooster? Age, height and torso?

Am trying to decide if DD would be close to growing out of it-
DD is 46 inches, 49 pounds and approx 17"+ torso.

My 10.5yo is like 51-52" tall, is still very comfortable in the high back Turbobooster; I'd guess she has another 2" of torso growth left. She outgrew the Nautilus harness a little over a year ago.

The highest setting on the Turbo puts the belt guide just above 19", so your kiddo would have another couple of years at least in it.

Yes, your child is very close with a 17" torso - it's like 18" tall, I think? My daughter outgrew it at 5.5yo. She's going to be 6 this week and she's 46" and 51 pounds, so I guess she was a little less than that around Christmas time when I noticed (she doesn't use it often). My daughter's all torso.

My 11 year old just out grew the back, not sure on her torso height at the moment, but she weights 82 lbs and is 4ft 5" , my son who is 4 ft 2" 58lbs still fits with at least a notch to grow, oh and he is 9.

Damian (the super tall boy who is 5'7.5" at age 12) outgrew the turbo when he outgrew his Britax Regent - age 6.5yrs

Jeffrey outgrew it around age 7-7.5yrs

Ruthanne is 8 and would still fit on the tallest setting or the next down (not sure as we don't own that seat so I'm just going off her torso height and what settings she uses on her boosters we do have)

So it just depends on the kid... Jeffrey is in the 75-80% for height, Ruthie in the 50% but with a longer torso for a LONG time (now closer to average torso) whereas Damian was in the 95% at the time for height and since then went into the 105% for height and has stayed there.
