Honestly there's a ton of good choices, but I'm pretty partial to the Tige's mesh back chairs. A lot of guys around here make fun of them because it's not a big plush la-z-boy style chair like a lot of boats have, but if spend time getting in and out of the water and then driving the boat it's nice because of how well the seat drains and stays dry. It's the one feature that I wish my RZ4 had instead of the "upgraded" seats. It still has the flip up bolster and is surprisingly comfortable, and you can probably find a decent deal on one from someone who upgraded theirs.
