Wow. I was so excited to try this TEMPUR-Breeze ProHi pillow complimentary in exchange for my honest opinion! I have absolutely loved the sleep I get with my TEMPUR mattress and had been looking to switch my pillows to match for added comfort. I first noticed that these pillows are pretty heavy! Normally, I wouldn't gravitate towards a heavier pillow, but it helps keep my pillow in the same place all night, which as a back sleeper, I love. It really supports my neck and conforms to my body leaving me feeling well rested in the morning. I also love how cool the material stays all night. My previous pillows were foam and always made me wake up sweating. I am looking forward to replacing all of my pillows with these.
