Big thank you to you all for the great advice. I've been doing some research on your comments and I feel that Chavant NSP looks to be what I'll try. I'll probably go the medium firmness first and see how I cope with that.
Secondly, aside from the great ideas some of you had for heat boxes, would anyone know if there might be an actual product that would serve the same purpose? Maybe a little pot kind of thing with an adjustable temperature? Maybe there's some kitchen product out there... I'll have a look.
Again, big thanks and I let you know how I go.
As always, love your advice.
Cheers - Chris
