I have not heard of wool mattress. Seems to have lost.

It seems, it only seems… Maybe because it does not talk about advertising and media…
No se’n parla perquè no interessa… Not interested, I mean, a les grans fàbriques que fan els matalassos com a xurros, and after 10 years say they've already thrown so spoiled (and yes you are right!), perquè fan servir materials molt sintètics, with expiration date, no chance.
Les deixalleries i els contenidors en són plens.El wool mattress és l’opció més sostenible per descansar. I speak both economic and ecological sustainability.

Makes the mattress with your hands, here, by Country (able to work here, course)

Uses sheep wool Pyrenees and wears cotton clothes 100%, both natural materials biodegrade completely.

I… yes, mattress is not necessary to change each 10 years, Become last many more.
