Well I solved the problem by getting no seats at all. I bought the Otter that attaches to the box of my Ranger. I should get it this week. Kind of took a risk and am flying blind on it as there was nothing as far as reviews or You Tube stuff to watch. I was able to look at one in the showroom and liked enough of what I saw to make a decision.
I have one of those tripod chairs with a back I usually take on the ice and it’s quite comfy. Plus there’s a plethora of camp chairs to choose from out there.
Anyway I have fished with both kinds of seats and much prefer the individual seats over the bench for comfort. And I would say that would be the most important feature of any seat. I have a buddy who will only by bench seats because he will lay down and take a snooze when he’s by himself and will spend the night on the ice.
I would say spend the extra money on the seats you find comfortable. You will only regret it if you don’t.
