How much you looking to pay?
www.iowa80.com has their top of the line for $1800 ea. or the lower model for $800 ea. These are both big seats and may need more than a day cab to fit.
Don't think I have seen a swivel air chair, but wouldn't doubt it is not out there somewhere.
I have 2 brand new Bostrom Talledaga 915's. Air, manual lumbar, recline, seat tilt, glide & lock out.
Asking $250 ea.
These where going to go in the sleeper for the kids until the that got axed do to length. I have the twins to these in my cab now, although we covered them in leather to match the rest of the interior.
I like these seats, because they are firm and have done 12 plus hour days in comfort. But I will say these are nothing like a thousand dollar seat.
