Don't purchase online if you are not sure if this pillow is for you. Test it out in stores. They don't accept returns on pillows. I will not be purchasing anything Temperpedic again. If you are someone who sleeps in multiple positions. This pillow is not for you.
As a side sleeper I could never get comfortable and woke up with a sore neck. My TEMPUR-Cloud pillow fixed both problems. Now I wake rested and with no neck pain.
