Aftermarket seat question

I'm too wide-load to sit comfortably in a Jetta or Touareg. The only VW I can
sit in halfway comfortably is a New Beetle; anything else, the seat bites into
my cheeks.

Can anyone point me towards a third-party, aftermarket source for seats that
could fit me? I recognize it's difficult with bucket seats. Please e-mail.
Thank you.
