English is the only language I speak, and have to say mine is rather excellent.

But I also did not understand the poll and the question was multi-faceted, it could have been:
1) Does anyone historically find that different seat coverings produce more back pain, if so which one?
or, perhaps more applicable in this case:
2) Does anyone experience back pain driving their C-HR, if so what seat covering do you have?
So I don't think well thought out or executed, sadly not even an 'e for effort'
Coupled with the fact that most of us haven't had our car for long enough to work out if it is long term comfortable or uncomfortable. I've done 1500 miles, the longest drive being 189 miles and find my cloth C-HR seats superbly supportive. That said, my jaguar and Audi both have full heated leather and, in the case of the jaguar, I've covered as many as 30k miles in one year and have always arrived as refreshed/relaxed as when I left...even on a 400 mile single journey to Glasgow without stopping was fine....sorry but my bladder couldn't hold out longer!
So my findings would support what Merly mentioned that it's about ergonomics and your own body posture/seat position more than the covering.
PS: Since I didn't understand it, I didn't answer either :lol:
PPS: 381 views and 7 votes (less than 2%) would indicate that most others didn't get it either.
