elements i.e. humidity, sun, wind, rain... or maybe sandstorms & tornadoes!  i mean completely to dust, in a couple of weeks/  that is an extreme transformation.  The good news is it's decades if properly cased, so i doubt there would be anything to worry about in that regard.  But you have to respect their honesty to even include a statement like that.  I like it- you have to figure the natural claim is legit anyway, because that IS biodegradable.

but has anyone with all natural latex been surprised by any degration at all (ever found ANY dust if you've opened your cover)?  how many years, always used your cover, what climate? i always run my a.c., sun would never touch my bed. i wouldn't forsee any problems. just found that statement fascinating.
