Suggestions please!

I currently own an '08 Honda Accord. Great car, except for seat comfort on long hauls. My wife and I both have some arthritis issues and are looking for suggestions as to which new car has the most comfortable seats. Price is not necessarily an object, but of course must be considered. I don't want an "old person's car" but I really need to know what you folks consider absolutely the most comfortable road car available. Thanks in advance!
