If you want a comfortable pillow that leaves you feeling well-rested and pain-free, the secret is adjustability. Adjustable pillows allow you to get the perfect spinal alignment because they accomodate to your sleep position, body type, and mattress density. An adjustable pillow puts you in control of your pillow, not the other way around.
Mold it. Shape it. Adjust the loft. Comfort should be in your hands.
