Why Natural is Better
Now you understand why chemical free natural fibers are better than synthetics. Synthetics are cheaper and easier to manufacture, especially in mattresses where polyurethane foams and polyester fabrics are common. But natural fibers perform inherently better. And in addition to breathing cooler and being antimicrobial, natural fibers are safe, non-toxic and environmentally friendly.
Only natural materials, whether certified organic or not, can be free of toxic chemicals. A natural bed is either a 100% cotton mattress, or a wool and cotton blend. You can find organic mattresses which are very expensive, or natural mattresses with some organic components.
Some retailers include latex which is derived from trees and can even be certified organic. But latex foam does not breathe and cool like natural fibers.
Natural sleep is healthy sleep.
