The Spoonk Organic Hemp Travel Mat works on the simple principle of acupressure - the healing art known as the Shiatsu massage. By stimulating increased circulation through acupressure points on problematic areas, you relieve muscle tension and pain, while at the same time rejuvenating and rebalancing the whole body. The stimulation points are made with high quality, non-toxic, hypoallergenic ABS plastic. Spoonk is the only brand that uses plant based, USA-made, CertiPur-US Eco-foam free from PBDE flame retardants and made using VPF technology. We use the highest quality of organic hemp fabric that has higher durability and natural antiseptic properties than conventional cotton. Our fabric is GOTS certified (Global Organic Textile Standard) and is made from a blend of 55% organic hemp and 45% organic cotton.
