I have a 94 M Mk 3 Avantgarde Cabriolet. The driver's seat is quite worn and a bit uncomfortable and the passenger's seat is like new. I'd like to swap them around but not sure if this is possible never mind how to do it.

The plastic surrounds are obviously designed for left and right placement so they cannot be shifted but my question is; can the seats be removed from their plastic housing and swapped, if they can has anybody got any tips on how to do it?

Thanks.
