Comfiest drivers seat of any car?

[OldGermanHeaps]

The drivers seat in my trafic van is worn, the metal is making its way through the foam so I am going to fit the seat from something else, as standard trafic seats aren't great. Others have fitted saab seats, range rover seats, laguna seats to their trafic vans without problems, the subframe lends itself to modification. I couldn't give a damn about resale, I'm running this thing until it is beyond economical repair.
I can fabricate brackets to fit anything, so the scrappy is my oyster. What is the comfiest possible seat I can get? Volvo? Saab? Something else?

Thanks for all the replies, off to the breakers at the weekend with a wee shortlist. I might try to get a heated seat while i'm at it.

got a new van, but the saab seats in the trafic were so good I did it again. just need to weld up a frame to fit the 60 part of the 60/40 rear seats out the saab to the passenger side, but its uncanny how nicely they fit.
