Thank you SO much! Got through to someone, who is now finding out what to do about it.  I really appreciate your help!

Thank you for that. He said he had previously had a latex futon but hadn't experienced the strong smell. Seriously - I have quite a sensitive nose and had slept on that mattress without any issues for 4 years, so I really don't think it's anything from my end.

I did report the most recent listings - still not easy, because there isn't a relevant option, and it's not clear that there's an actual human reviewing those reports and doing anything about them.
