Steering wheel height adjustment

I have a 2006 Peugeot Symbol but I find that the steering wheel height is too low even with the seat down as low as possible. It has tilt adjustment but no height adjustment. Is there any type of adapter available to raise the height?

I have a 2012 Dorset on Peugeot Boxer with similar problems - no height adjustment.  Fortunately, I am able to adjust the seat in such a way that it isn't really a problem for me.  Due to the way the steering mechanism is mounted in relation to the dashboard, I cannot see any way of easily adapting the steering to raise its height.  However, the best option might be to speak with a specialist who modifies vehicles for use by disabled people as they tend to have all manner of fixes available to suit a wide variety of disabilities.
