Challenge: a pillow thats always cool

Former Member

Hey there,

I can't speak for everyone, but I know a LOT of people, including myself, who love to sleep on a cool pillow. The problem is, the pillow warms up quickly and it's not as nice. Of course you could move your head to each end, but who's going to be able to fall asleep doing that? Anyway, if there's any way you could create a pillow that stays cool yet remains comfortable I'd love to see it!

  • An always cool pillow has been on my wishlist for a long time. I like the ideas proposed. I would lean towards something that was passive in that there were no pumps or active mechanical devices. This could keep it quiet (important during sleep). The challenge is conducting heat away from the head. It would be neat if you could actually generate heat from the temp gradient -- a pillow iPhone charger would be crazy - although would it really save money? probably not. I'm less familiar with the peltier devices, but if you have a temp gradient across it, it generates electricity, how much?  And as Ben said we'd want it to be soft.
