Question Next seat for almost 8yo


New member
I'm looking for advice on how to proceed. I have a soon-to-be 8 year old (in August) who weighs 58lbs and is 4 ft 4 tall. He's currently in a Radian RXT (forward facing but in harness mode, not booster mode). It looks like he's outgrowing that by shoulder height - his shoulders are bumping up against the sides of the head rests, and it's uncomfortable for him.

I'm assuming I should get him a high-back booster that will last him another couple years? What can I get him that he likely won't outgrow quickly, that's comfy and of course safe? Willing to spend more money for a seat that will last him longer and/ or for a seat as narrow as the Radian (see car situation below).

Additional info: My other kid is a small-ish 5-yo. She's in an Evenflo SureRide/ Titan 65. I'm assuming we'll switch her to the Radian when her brother gets a new seat. They are both in the back of a Subaru Outback. Currently, we cannot fit an adult in between the two, mainly because of the Evenflo. If we could get a booster for the older kid that's as narrow as the Radian we might be able to occasionally fit a person in between the two kids' seats, and that would be a bonus (not a must though). Also, we also own a cheap simple booster for traveling - but I'd strongly prefer a high back booster if it will last us another couple years.

I would love to hear your input on what to buy/ how to proceed. Thank you so much!

I would go with a booster. I am not a booster expert, but off the top of my head, I believe the Evenflo Spectrum is tall, narrow, affordable, and pretty well available.

The Spectrum is not very narrow. Especially at the head, but the bulky and boxy shape at the hips are not narrow.

I'd look at the Evenflo Big Kid/Amp, which is ok at the narrowness, and the Harmony Dreamtime. The Peg Perego Flex 120 is also very narrow, but very expensive as well.
