I have some original 60/40 seats in my JEEP currently. I don't like the coil and spring suspension as it can bounce me pretty good on the trail. Plus, I'd like to free up some space. I have a set of intermediate low backs that are solid, but a little aged and could use covers or new upholstery (they are the foam without springs and coils). I have the original bucket seat brackets from my JEEP to mount them (will need to adapt passenger side). I have a set of original '64-'65 bucket seats (frame integrated in seat) that need upholstered, but they have similar coils and springs as the bench seats, and I am concerned they will also be "bouncy". For some reason I am really wanting to order a set of these. Does anyone here have experience with smittybilt low-backs? So, what should I do? Am I imagining that the original coil/spring seats really throw you around on the trail? Are the Bestop low-back covers pretty solid?
