It takes time to perfect any product that works. Yes we are getting older but still want to help people with sleep problems. All pillows are made by us in 5 sizes to give you the right head support for a deep sleep. A deep sleep will keep your imunity system healthy and ready to fight any normal bacteria infection. Over the 25+ years, my wife and I have seldom caught a cold or the flue. I do not remember having a cold like I used to get with a bed pillow.
