We recommend this or any of our natural latex mattresses to be on a slatted bed frame or foundation in order to give proper breathability the latex needs.
The quilting done to our premium ecowool and organic cotton damask outer ensures that the wool will not migrate out over the years. No poly-backing, treatments, or chemicals in any of our wool. Our wool is strictly tested, you can see the test results for our wool and other raw materials in our organic certifications section.
