Sorry for hijacking this thread. Avant, please feel free to move this to a separate thread if it's inappropriate.

I've just bought a Yaris (1.3 T3) of this age. When I test drove the car it handled well, I liked the interior and, crucially, the car seat fitted against my back and seemed to offer excellent support, something which the new Fabia seats didn't. On this basis I bought the car but I'm now experiencing severe backache. The last car that did this was a Ford Fusion. We had to get rid of it within the week and we were fortunate not to lose any money. A few days on, I'm trying a variety of cushions to alleviate the pressure which seems focused on the coccyx.

Has anyone else experienced this and found a solution? Our problem is that we needed the car to serve multiple purposes: a cheap run around and a low insurance for a provisional driver. If these hadn't been factors I'd have bought an old luxury barge like the Rover 75 to pamper my back. Incidentally, I rarely ever experience back pain outside of driving.

All help will be most gratefully received. In the meantime I'm trying a super-duper wedge cushion, pricey but much less expensive than changing the car after a few days' use!

Thanks, Avant. I really can't work it out what our problem is with car seats. I've looked through the windows of several similar Yarises (Yarisi?) and not a single one has contained a cushion of any sort. Given that they're well-liked by the older generation presumably they're comfortable enough for most people to cope!

I'll use the car (+cushion) for a longer journey tomorrow. If I'm crippled by the end of it then I'll at least know that it may be necessary to take drastic action! I've even considered having the seats retrimmed or replaced as the car is ideal for our purposes.

Thank you. I'll give it a try.
