Hi, everyone

Not sure if this is the right place for this post so apologies in advance if it isn't and also if it's considered a daft question but here goes.

My wife isn't very tall and when she tried our new 208 even with the seat height adjusted as high as it would go she still reckons she still too low in the car to drive safely.

As this is potentially very inconvenient I wondered if using an extra cushion or something similar had any safety implications as obviously it wouldn't be fixed to the car in the case of an accident. I'm thinking particularly relating to the operation of the seat belt.

Any advice gratefully received.
