Cool Cushion is exactly that
I ordered this for the many hot flashes I have now.  I use it mostly at night.  It works well, assuming you follow the directions for filling it to the letter.  My boyfriend has found it useful for sunburns or for sprains or muscle aches.  It's soft so it doesn't irritate your skin and feels great when you think you're about to spontaneously combust.  Women over 50 will know what I mean and will appreciate the comfort you get from this.
