Had this pillow bought for my three-week vacation. It's totally easy to use, rausholen the rolled pillow from the supplied case, turn on the screw cap and the cushion inflates by itself. (You can also blow air into it when someone's pillow is too soft) It is extremely comfortable and I had a great sleep. I had at my use of a pillowcase over drawn around it ,, 'to have a little domestic' :) After use the Drehverschulß simply turn up again, roll pillows together and wrap back into the envelope. I can only recommend the pillow!
