Why wool?
Wool is uniquely comforting to lie on. A natural insulator, it helps your body feel cozier in the winter and cooler in the summer. Wool doesn't develop hot or cold spots, so you'll shift and turn less while sleeping. Wool is plush without “poofiness”, so even a light layer keeps you comfortable.
Wool fibers have microscopic scales on each strand that wick away moisture and prevent a "clammy" feel. Used as batting either in a mattress casing or to fill a topper or duvet, wool promotes a comfortable sleeping climate.
Another key benefit of wool in mattresses is that wool is naturally slow to ignite. A mattress made with wool batting inside the casing can meet federal fire safety requirements with no chemical flame retardants.

Organic wool
Certified organic wool is free of synthetic chemicals throughout the processing. The sheep graze in organic pasture, the wool is cleaned without bleach or solvents, and the garneting and carding are done without chemical additives. At Savvy Rest, we use only certified organic wool.

Is other wool organic?
Some will be. Bear in mind as you shop, however, that the terms “pure” and “natural” or “eco” or “all natural” or “100% natural” do not mean organic.
Unless materials are certified “organic”, they may still have been produced with harsh chemicals, dyes or pesticides.
The Savvy Rest Organic mattress casing contains only certified organic materials. Verifications from widely respected, independent agencies are credible. Less reliable materials are only "described" or "stated" to be organic, or are "self-certified" organic by a manufacturer. You can see our organic certifications here.

Organic cotton fabric
Conventional cotton production has a devastating environmental impact. Thirty percent of the world's pesticides are used to grow it, and enormous quantities of chlorine, toxic dyes and finishing chemicals are used to process it. Choosing organic cotton really makes a difference.
It's important to understand the difference between cotton fiber and cotton fabric. Fibers are strands of material made from cotton, polyester, wool, or silk. Cotton fiber is used extensively in mattresses because it is very cheap to produce. Strands of the fiber trap air, creating loft, which can give a mattress a comfy feeling—at first.
Have you ever sat down on an old futon? Mattresses filled with cotton fiber, organic or not, will harden. They also tend to take body impressions, some severe enough that you may eventually feel as though you're lying in a gully. Cotton fiber also attracts moisture, which causes it to compress or pack down.
Cotton fabric is different. It is made from spun thread, not loose fiber, and it will not compress. The woven fabric is very appropriate for mattress casings and for bedding. It’s soft, breathable and comfortable next to your skin.
