Need a BIG, squishy pillion...

[SCARYGLIDE]

Hello all ! !
I am modding a VW trike for my wife, and I am in need of a BIG squashy pillion to use as a primary seat.
If anyone has the passenger part of a two piece touring "sofa" and you don't need it anymore, we will give it a good home.
The wider and thicker the better.
Think the factory two up seat on the early to mid '90s Electraglide passenger seats, and you will have a good idea.
Thanks,
Mike
