DR-HO's neck comforter is a cervical traction device that can stretch and relax the neck and shoulder muscles while improving your spinal posture. Use the high-efficiency hand pump to inflate the neck comforter. Partially inflated, the neck comforter functions as a neck support, perfect for resting or travelling. Fully inflated, the neck comforter will support the weight of the head, reducing stress on the neck and shoulder muscles while promoting better posture. At the same time, it will stretch the muscles and decompress the spinal discs of the cervical spine. The neck comforter can be adjusted to your own comfort and does not require battery, chemicals or drugs. It is portable, safe, painless and easy to use. One size fits all.
