I’d like to buy a nice, smallish, bouncy pillow with a battery inside it that keeps the pillow somewhere between cool and room-temperature normal. I don’t like resting my head on overly heated, faintly damp pillows, which they all eventually turn into due to body-warmth (or head-warmth) transference. We’re always flopping the pillow over so we can sleep on the cool side, and this is the solution. I’ve been surfing around for cool pillows but haven’t found any so far.
