Hello! Are the headrests in Volvo fixed to the seat, or can you take them off anyway? Up to what height do the headrests fit optimally? Are there longer headrests in Volvo, for people who are too short the built-in headrests? Another question I would like to ask, I have set my seats in the current Citroen and Fiat quite “straight” so that you can not dive under the belt (submarinering), “interrupt” the headrests in Volvo, which are very na Is there any kind of inflatable pölster under the seats because of submarinering (dwelling under the belt)? I have read something about it on the Internet. Thank you for your answers Friendly greetings Franz
