I’d never heard of a D-Core pillow until several years ago I visited the emergency room with an intolerable headache. I had never before suffered anything like this pain, which was so severe it nearly made me nauseous. After lots of tests, the ER doctor suggested that I visit — GASP! — a chiropractor, because the tests showed no organic dysfunction, and, to make a long story short, one of the remedies the chiropractor recommended was something called a D-Core Pillow that (surprise!) her office happened to sell. The headaches, she explained, were caused by neck strain, and the pillow (along with some chiropractic adjustment) would relieve that strain.
Needless to say, I was skeptical that a mere pillow could be part of the solution, and that THIS particular pillow (that the doctor herself was selling) could help, but after a single night’s sleep — no kidding, it took ONE night — my headache was barely noticeable. After several days, I was no longer experiencing headaches at all. They were caused, it seemed, by poor cervical alignment, which the shape of the pillow helped to correct as I slept.
How does it work? The pillow is shaped like this:
The core in the center of the pillow, which is shaped (obviously) like a “D,” cradles the back of your head, while the surrounding cushion support the natural curvature of your cervical spine. As I’ve learned the hard way, this curve can be disturbed, or your neck otherwise severely strained, if you sleep on your stomach (my favorite position) or on your side without adequate support for your neck, or if you spend too much time hunched and leaning over a computer keyboard, tablet, or mobile device (have you noticed that Bill Gates’ head leans precipitously forward even when he’s simply seated upright in an interview chair?). I have tried many (many!) other “cervical support” pillows over the years — memory foam, buckwheat hulls, side-sleeper shoulder-supporting — and each one of them has caused me to awaken with stiffness in my neck and shoulders. The D-Core is the only pillow that not only prevents that morning strain but relieves any strain I’ve accumulated in my neck or shoulders during the day.
The only bad news about the D-Core pillow is that it’s not really packable for travel. You can — as I do — stuff it into a suitcase and compress it to allow room for the rest of your belongings, or you could get the “mini” version that’s about half the size.
I’d be thrilled, though, if someone designed an inflatable version so I could more easily take my very necessary neck support on trips, and I’d be interested to know via comment whether anyone has found a comparable inflatable solution. In the meantime, you can get the D-Core Pillow or its smaller sibling fairly easily from Amazon.
