If you are constantly waking up with a stiff neck, chances are the pillow you are using is not supportive enough for you. When a pillow is too flat, the head weighs it down and your shoulders become pressed against the mattress. Pillows like the NRG Cervical Support Pillow offer firm yet comfortable support that slips in between the mattress and your shoulders and keeps your neck straight when you sleep. This will alleviate the stress on your neck and minimize your neck pain.
