Hi John667,
I’m happy you went to try out an organic dunlop latex mattress!
Yes, you can easily get 20 years + out of a dunlop latex mattress. That’s why most manufacturers feel confident enough to give you a 25 year warranty. Here is a video of a 50 year old dunlop latex mattress and as you can see on the video it’s still in good condition.
The whole story about “natural latex” is quite confusing, but it mostly applies to Talalay latex more here on the subject. In our experience all the organic dunlop latex is at least 95% rubber and the other ingredients include:
1-Organic Latex Rubber 90-95%
2-Zinc Oxide 2-3%
3-Fatty Acid Soaps 1-2%
4-Sulfur 1-2%
5-Sodium 1-2%
Please see this article on the pro’s and con’s of dunlop and talalay latex

Last thing… The King Size was about $3800 and the split king was like 5500$. The guy told me he simply cut his layers in half and bought independant double XL covers and made his own split king. I wonder if I’d have the balls to do this but it looks like a good way to save some money.
[/quote] Yes, you could simply cut the layers yourself. The organic cotton sleeves are an option and not necessary in our opinion, as the latex is already well covered my the actual wool quilted organic cotton cover and do not to be covered a second time.
We can easily make you a KING split with a brass top zip wool quilted organic cotton cover with these specs
S 2"
S 2"
M 3"
F 4"
For 2995$ taxes and delivery included. This is our Presto mattress, and the latex layers are loose (like the greensleep) so that you can fine tune your comfort and support options.
Did I answer all your question?
Please let me know if you need any further information.
All the Best!
