Which high back booster for older DC (7+)?

[SerenaVanDerWoodsen]

We want DC7 to stay in a high back booster, even though they are above the threshold for a backless booster. The seat we have at the moment seems quite narrow already though. Can anyone recommend a roomier high back booster that should last the distance?

Britax Römer has the best seats for this age category.
