Thanks John. Most grateful. Mine is after 7 miles!
I weigh 10 stone and 5 lbs and am 6'1".
The passenger seat is fine as are the seats on my ex-wife's car. There is no way my posterior or weight could cause such a deformation in such a short space of time.
Basically, the driver's seat base is buggered.
