Comfort Memory Foam Neck Roll and Cervical Bolster Round Pillow with Removable Washable Soft Cover for Spine and Neck Back Lumbar Leg Vertebra Support (18x6 inch Pillow)

The product is of good quality, quite firm. I like the fact that it is short, I bought the smallest one. I can use it as neck support, with my feather pillow. I have been actually using it as support between my knees when I sleep on the side. It doesn't have the nasty smell that some memory foam products do. To relieve the pain it must be used on a regular basis, for a longer period of time (3-4 months). It takes time for a bulged disk to cure. The neck support cannot be very comfortable as in nature, they are quite firm and so is this product.
