I guess that includes 100% natural tree sap latex. My mattress is 100% latex, with 100% undyed cotton without any other treatments. I'm enjoying the mattress its comfy and never smells bad (smells like latex up close), it doesnt absorb anything, but has holes for air so its good. I could clean it with just water. Only problem I'm having is that ozone generator degrades it instantly, after 15min it already is visibly starting to degrade if I put the ozone generator directly on top of the mattress, and UV lights also degrade it.. Now you say it is toxic. Doesnt seem like a good choice. Also it does leave a smell after ozone generator is on for a while, the whole room smells for some hours after. What alternative is there? Something that doesnt host bed bugs and can be easily cleaned? The common mattresses suck imo they absorb all the sweat and are thick, needs a deep cleaning machine and try hard to get all of that out if possible. Maybe just a very thin natural cotton mattress that water can easily penetrate for cleaning. Or linen I hear is good to keep microbes away
