The comfortable Naturally model is, just like the name implies, an entirely natural bed. All Hstens beds have been built for generations using the same natural philosophy. Natural material has many advantages including the ability to follow and relieve pressure from the body while at the same time allowing air to circulate while you sleep. The new improved Hstens Naturally also includes genuine horsehair stuffing. This means that you can lie on one of the springiest and most elastic filling materials available, which keeps you dry and at an ideal temperature. The bed uses a technique in which pure cotton and wool are blended, combed and prepared in a unique way which makes Naturally a naturally comfortable and pressure relieving bed. Hstens’ unique new patented spring system working in conjunction with natural stuffing material gives Naturally great pliability.
