I've got the baja rs in my JKU right now on corbeau pedestals, and the position isn't bad for me at 5'10", but they are by far the most uncomfortable suspension seat I've ever sat in.I think that might be because I'm too light though, I have a buddy with them in his who is much heavier, and find his exact same seats much more comfortable. And I think it's because he's broken them in.
The most comfortable for me is the baja ss ultra wide set that are in my TJ, I made my own mounts to put them on the factory sliders, and I can tumble them, but since it's not a reclining seat, it still doesn't give much room for access behind them, but I don't have a backseat there anyway.
I've also had the baja JP in my scouts, it's a direct bolt in seat to Scouts, and Jeep cj and yj, will require an adapter for TJ. They are almost as comfortable as the SS, but have much lower side bolsters, so they don't hold me in place as well as the SS on rough trails. That might actually be better for larger folks though.
