Buying a new one any branded ordinary pillow usually you're paying from 100 to 200 Eur for a pillow and you have to do so at least every few years because of care about your health, hygiene and healthy sleep especially. By the way, you will be happy if you find the right one for you.
Taking care of yourself during the whole lifetime ( if we count 55 years of independent adult life) you'll be buying such a pillow at least 27 times and will be spending from 2 700 to 5 400 Eur, wasting your own precious time and hard-earned money.
"So, you need to be changing your pillow, probably about once every 18 to 24 months, you need to be changing your mattress about every 7 years" Michael Breus, PhD Sleep Specialist is telling us: https://www.webmd.com/sleep-disorders/video/breus-touch-sleep
