Hi Bcgirl,
This would likely be a 6" layer and a 2" layer (latex molds are generally about 6" thick) but it really wouldn’t matter because your testing is more important than the specs of the mattress as long as you know the specifics of the material.
Again I would focus more on your own experience than on the specs so you don’t take on the challenge of trying to design your own mattress based on specs. I would tell the retailer or manufacturer that you wanted something softer and more pressure relieving and then let your body decide whether the softer alternative worked better for you. The “how” behind why it was softer would be less important but having said that I would probably tend to go with a lower ILD although this would also depend on the specifics of the other layers and on your body type and sleeping positions. When you are testing mattresses locally then your own actual testing and experience is always the most important thing to focus on and the specs are secondary (and likely to do more to confuse than help).
The value of a mattress depends on what else is available to you, what you are comparing it to, and your own personal value equation, (value is relative to each person, area, and situation in other words because a mattress isn’t a commodity which is sold by the pound). It would also depend on the size of the mattress you are purchasing and on whether it’s a set or a mattress only but if it’s a queen or larger then from a materials perspective it certainly seems reasonable to me.
Yes … they make high quality Dunlop latex and they are one of the latex manufacturers that has GOLS certified organic latex (see post #6 here and post #2 here). Their US website is Latex Global.
No it would be fine.
