Help with back problem with several types of beds

Thanks for your reply.

I don’t think it’s a medical issue, because I sleep very well on many hotel beds and I am in excellent all around health.

Since I can unzip and put in a new topper to my Hybrid Coil bed (I have no doubt this is a great product, it just is not working for me for some reason), I’d like a recommendation on things I might try.

I think trying softer is a good suggestion, since I guess latex is considered firm? What would you suggest?
Could I try something that resembles what is in my couch. It does not bother my back.

Are my questions only going to you or to everyone?. Maybe I could get suggestions from other people as well, that maybe have also encountered this problem.

Any suggestions would be appreciated.

Thank you,

Ellen
