Inflatable body pillow for the side sleepers who travel for work or pleasure. Pillow measures 13 inches wide and 48 inches long when inflated. It comes with a handy drawstring carrying bag. When inflated, the pillow is approximately three to four inches thick, depending on if you want a rigid pillow or something more cozy. The value on the pillow allows it to be blown up with your mouth, or you can use a blow dryer on cool setting while depressing the value to blow it up quickly. While only 50% of the air will probably make it into the valve, this method only takes a few seconds to complete. Blowing it up manually will require similar effort to blowing up an adult pull float. If for any reason you are not happy or have questions, please reach out to us! We love to hear how the pillow works or where we can improve. Your satisfaction is our guarantee!
