Seat elevation for Passport 12?

I was just wondering if anybody has come up with a good solution to raise the seat on the Passport 12? I really enjoy the PP12, but find that the seat sits a bit low and is prone to coming detached from the securing arm when leaning forward. If anybody has come up with a solution to either one, I'd love to hear about it.

New Passport owner here, and I see I'm replying to an old post, but maybe this will be helpful for someone~
I purchased this seat pad for a different kayak I've have and tried it in the Passport today. I've only had my Passport out a couple of times so far and still getting used to things. Although it wasn't a lot of elevation change I did notice a difference.
