I had intended to fit diono radians three across in my Toyota Sienna, but my son has outgrown his for height. So I am looking for a narrow booster seat. I want the high back kind, I guess. I don’t know anything about boosters, since I had intended to use the Diono all the way through. Do I want a five point harness kind or just a belt positioner kind? My son is 8.
