Our shredded rubber comes straight out of the rubber tree - no petroleum here! As an antibacterial and hypoallergenic filling, this pillow uses it's incredible malleability to support your head neck and spine. What's more, this pillow will never lose its shape. Every pillow contains a plethora of harmful allergens and irritants such as mold, dust mites and pollen. Barrier cloth pillow cases effectively stop these irritants from reaching your face (and lungs) while you sleep. Most barrier cloth pillow cases are made with a petroleum based fabric, which is uncomfortable, and produces noise when touched. Through our innovative manufacturing techniques we have created an extremely dense organic cotton fabric which is more effective than most plastic pillow covers, yet remains soft, quiet, and best of all completely organic!
