Since the neck support is so important, we found it necessary to design a cervical roll that complimented the Sacro Wedgy®. We made it convenient for travel, 10" long, high enough to support the average neck curve, 4" in diameter using a very dense foam and with a blue, poly/cotton zipper cover to complete the system of stabilizing and slightly elevating both ends of the spine. The only thing left to do is the most nothing" you can do -RELAX and really let gravity to the work. The neck support retails for $12.95 but with volume pricing this package is $10.00 each.
