Natural latex pillows are pricier than their synthetic counterparts, but will give you 10 years of good service. Natural latex retains its loft superbly well, meaning it will last years before it starts going flat.
A natural latex pillow is filled with natural rubber made from the sap of the rubber tree. A rubber tree is tapped for its sap (also called milk), much like maple syrup. When the bark is scraped, it releases an antibacterial agent, just like our own bodies do if we sustain an injury. This antibacterial mixes in with the milk, and this is what repels dust mites.
Natural latex’s inherent dust mite resistance makes it a good choice for people with sensitive respiratory systems like asthma and allergy sufferers.
