Child aged 9 - booster seat or child seat

[mondaymonday]

DS is 9yo and is currently in a child seat (over 135cm tall). Just wanted to know what other people do - do you use a car seat or just a booster seat?

Ds 9 is in a booster seat.

No need legally to be in either if over 135cm tall. But if you prefer something then deffo just a booster. Neither of mine would tolerate a proper car seat after the age of 7 - too babyish!
