There is no such thing as a comfortable helicopter seat. The designers design the aircraft, and then suddenly realize a pilot is required, so they cobble up something at the last second so there is a place to sit. That is the case for every model I've ever flown. Most are fine for 10 minutes or so, but when you have to spend 10 to 12 hours in the seat every day, they're torture. Even the cheapest automobile has seats which make helicopter seats seem like torture devices. Plus, even the cheapest automobile doesn't leak water all over the driver.
