Has anyone had a problem with their lumbar bladder? I haven't taken the seat apart yet but judging by the lumpy appearance of the back of the seat, I'd say something happened to the bladder. Obviously, it's holding air but the way you can see big-ass lumps on the back of the seat, I'm thinking there's some kind of rear support that has failed. Any input on what I might expect to find once I disassemble the unit would be greatly appreciated.
