These seat covers are made from 100% Australian Merino Sheepskin with 1 inch Wool length. Easily fit car seats, airplane seats, office chairs, wheelchairs and many others All-Season Comfort Sheepskin seat covers are great for any season. They keep you cool during the summer and warm in wintertime, because of the breathing properties of wool's hollow fibers. They are always comfortable because they are extremely soft, and they provide a comfortable cushion of air that acts as a temperature insulator. Sheepskin is able to absorb sweat immediately and can submit it in to the air seven times faster than synthetics. Sheepskin against the body activates the blood circulation and the immune system supporting the relaxation and regeneration of the body. Sheepskin is gentle on your skin because it contains lanolin, a basic substance similar to that found in human skin. Added Value While your seat covers are protecting you, they will add resale value to your car by protecting your expensive upholstery from wear and sun damage. The natural lanolin in sheepskin will actually improve the durability of leather seats over time, making sheepskin seat covers a great investment.
