I have been using a Sleep Number Cool Fit Pillow that i recieved for FREE from smiley360.com because i completed the requirements. I have been using it for about a month now and let me tell you my sleep has never been better! Not once have i woken up with a sore, sweaty neck! It's great! I must say, after using that pillow, i don't think i can ever go back to using a "regular pillow!"
I would recommend this pillow to anyone wishing to get a great nights sleep!
