We bought twin & full size mattresses for our kids a year ago from Savvy Rest bcse we didn't want them to breathe in all the chemicals that are in standard mattresses. Plus, most standard mattresses last only about 5-7 years. They end up in landfills, etc.
Besides being eco friendly you one can replace just the biodegradable layers (1, 2, or 3 of them) and keep the organic cotton/organic wool cover, which repels bed bugs (plus bed bugs don't like to live in natural latex), and wool is naturally flame retardant. On the occasional nights that we ended up sleeping with the kids, the mattresses felt nice on our backs but we were also happy with the Sleep Number we had for several years. However, the Sleep Number started failing us too....it felt like we were laying on a hill. Luckily, we were able to...
My wool topper is fluffy wool inside of a cotton cover. We had a king with our king sized flobeds so after we switched to 2 x twins due to my wife's restless legs syndrome, we couldn't use the topper any more. Finally I just cut it down the middle with scissors and am still procrastinating getting someone to sew it. But it's about 2" thick but if you squeeze it with your hand it goes down to 1/4-1/2". The way they made it, it seems not to "bunch" inside. Right now I'm loving it.
I don't think the feel of it is that noticeable - it's very subtle probably for most people. But I think it does insulate me from that "right on latex feel" that I'm not wild about. I think if you get the fluffy kind you might be okay with 3" but...
An example is <a href="http://www.latexmattresscompany.com/">Latex Mattress Company</a> which offers BOTH sewn and zipper cover mattresses. The sewn cover models require motor freight shipping. The zipper model components can be shipped via less expensive UPS.

This is a very interesting video sager66, as per usual you do an excellent job of providing interesting links. This company offers an enticing price for their mattresses. Unfortunately they also get an F. rating from the BBB.
Were it not for your link to the BBB site I could not have looked...
You probably already know my opinion, but for others that may land here in the future:
I think memory foam is the worst thing for people with low back pain! Even if it works at first, it's just a relatively short time until it stops working. My view is that memory foam isn't really good for anyone; but people with no sleep "issues" can usually sleep okay on it. I will say that Tempurpedic is better than most other memory foam but still it only contributed to my back pain.
Latex on top of springs is what I think works best. Pure latex, no PU foam at all! (I do have 1/4" of very firm HR foam on the bottom but the rest is 1 and /34" of latex.) Some people may want 3-4" on top of the springs but for me just 2" works great.
