My husband has a bad back and wants a rather firm cushion. I have been doing lots of research and I am considering a Hancock and Moore. We do not want any down or feathers.

My question has to do with foam density. I read the attachment provided on this forum about H and M cushions and see it describe the Qualux seat cushion. I read the following about H and M cushions from a different forum:

"the foam core found in the standard, Ultra Down and Spring Down comes in two densities: 2.6 (standard) and 3.1 (extra firm). I don't know what the units of measure are, but it's all about how 'dense' the foam is."

Is it true that the Qualux cushions come in two densities? Any comments how firm the "extra-firm" cushion feels?

Thanks!
