I have a 6" pedelstal on top of the boat seat, I have the camo Big Mans boat seat with high back from Cabelas--one of the better purchases I've made the other year. When sitting on it, my eyes can see over the blind to scan the water/horizon for incoming ducks that are low. I hate crunched kness (like sitting on a couch-puke!, as I like sitting in a chair at dinning room table) as I have a back/knee problems.
The pedelstal was a fixed 10" tall one, I cut the center 4" out and had it rewelded for a custom height. It has slots for 4 bolts lower and 4 bolts upper, and the swivel is between the chair and the pededstal. Yes, it is permanent and not removable for quick stowage.
