Hi Momma Di,
Yes I’ve seen the video which is here.
You can read my comments about the video and the other comments you made in post #4 here and the other posts it links to along with post #4 here (including a link to a video of a Dunlop latex mattress that was in use for almost 50 years). As you can see … I don’t agree with your husband’s conclusions and my own thoughts are very much in line with dn’s that the choice between them would be based on personal preference and not based on the fact that one is any “better” than another. They are just different.
