Sorry, little bit long, but...I had some very severe neck pain. I say had because this pillow took my neck pain from severe to mild! The doctor recommended sleeping on my back, which as a side sleeper seemed impossible. Since this pillow is adjustable that made this easier to do for me. I was using a contour pillow - don't need that anymore! I loved the fact I could fluff it up to get the maximum fluffiness to sleep on my side! Paid extra for the cooling - for me totally worth it! I preferred to use the pillowcase provided to get the most cooling effect. I didn't need to use one of my pillowcases too - nice! Then to boot this was on sale! So good I bought pillows for my kids too! Phenomenal job, Temperpedic! Thanks for helping me out! I know not everyone might feel the same but I hope this review helps at least one person out!
