I ordered a ladder back chair from Parker and they actually sent me the deluxe helm upgrade. Decided to use it on our 2320 demo rather than sending it back. Then I used the stock chair for the duel pedestal seat project in my last thread. I have to say this deluxe helm chair is high end, very comfortable and looks good. You sit up higher and further forward which is great for visibility, but I had to mount an additional foot rest so my feet weren't dangling.
