Hi Phoenix,
I will get tested for allergy to latex.
I handled the bare latex samples a fair bit and didnāt get any skin irritation.
My sinus reaction to the latex mattresses was less immediate than to memory foam mattresses, but more long lasting.
To me, memory foam just smells like an oil field. The smell gets on any clothing that comes in contact with it and must be removed. It would make me ill in a different way, I think, if I slept on a memory foam mattress. But, just lying on it for 15 minutes, I donāt get the stinging sinus irritation or long lasting sinus pain.
To me, latex does have an odor, but it is not immediately offensive. However, as my body starts to react to it, I want the smell off me, just like I want the memory foam smell off of me.
For polyurethane, would it be correct to say that a membrane type mattress encasement would not help with out-gassing?
Are there specific brands, product names, chemical compositions, processing steps or other ways of specifying polyfoam so that I get a mattress with a short out-gassing period?
Does just specifying greater than, or equal to, 1.8 lbs (per ?) assure high quality/durability - without regard to manufacturer, etc?
Thanks for a truly enlightening post.
