Non-Isofix car seats for 6 year olds

[EmMay88]

Does anyone have any recommendations for secure car seats for slightly older children (a 5 nearly 6 year old) which don’t require isofix attachments (the back set of seats in my car doesn’t have isofix). Huge thanks in advance for any advice!

You just need a high back booster, even if the seat has isofix it's optional to use; you can just use the seat belt (which you must do including when there is no child in the seat, as it keeps the seat in place).
