I've got a used GTS seat for sale. I THINK it is the Sebring model, and I can't verify that the inflatable back pad works, but it has plenty of support. It has very slight wear where the seatbelt comes over the shoulder. It also has a crack on the plastic grommet where the headrest meets the seat.
Finally, it has two dimples on the bottom cushion where it looks like someone set a box on it for about a month. All of these imperfections are very slight. Price is $700. I'd prefer not to ship it, but would be willing to meet someone at Octeenerfest to deliver.
Thanks,
