Seat covers!
Where do you start?
A good starting place would be the AJOR vendors list. Many of them have seat covers.
Then decide if you want vinyl, cloth or neoprene.
I wanted cloth covers and went with Rugged Ridge. Tailored fit and perfect colour match (until they fade
).
Added bonus: the drivers seat base wasn't very supportive. The straps for the Rugged Ridge seat covers clip tight around the seat base and really firmed it up. I now sit ON the seat instead of IN it. It's like a new seat.
