Question regarding Pure Latex Bliss Eco

Thanks for the information. The post you referred to on wool covers was very useful and interesting. In searching for customer reviews of the “Sustain” model I’m considering for purchase, I came across this site, which purports to have the specifications for all the layers for PLB mattresses. It suggests the layer arrangement is:
[table]
[tr]
[td]Layer Type[/td]
[td]Thickness[/td]
[td]Description[/td]

[td]Comfort[/td]
[td]2"[/td]

[td]All Natural Talalay Latex - 36 ILD[/td]

[tr]
[td]Cover[/td]
[td]-[/td]
[td]400+ gram washable / removable cover w/ ActiveFusion. Organic Cotton w/ wool fire barrier [/td]

The specs for the other PLB mattresses on that web site are close but not identical to those specified in post # 2 here.
