When should you get that new pillow? You should get a new pillow when you feel like you are not getting the support that you need. Also, after a few years, you should def think about replacing a fiber and foam pillow just for hygienic reasons. It is a good idea since both materials do break down after time.
First day felt fantastic! Crippling after that. Extremely disappointing. I have been looking for a comfortable pillow for 8 months after my fusion, hoping this was it, sad to say it was not for me. May work for someone else, but increased my pain. - Tausha
