In our Churchill Signature Collection we have our Latex Wedge Pillows which are handmade by local American Artisans and made with natural Dunlop Latex wrapped in our Organic Cotton stretched knit cover. Dunlop Latex will provide long lasting comfort and durability without the use of polyurethane foams and synthetics. Natural Dunlop Latex is known to be inherently resilient. It expands and conforms to the various levels of weight and pressure to which it is exposed and does an excellent job of relieving pressure points and causes less tossing and turning. Natural Dunlop Latex is also considered the most durable of ingredients. Its longevity goes far beyond that of synthetic ingredients. The open-cell structure of our latex allows air to pass through naturally and dissipate quickly making it highly resistant to dust mites more so than any other foam. This makes it the ideal choice for allergy sufferers!
