Instructions for first use: 1) Apply a hot towel to the neck before traction. 2) Start traction from the lowest point for the first time. If there is no discomfort, increase the time and height. 3) Find a comfortable position without overinflating and raising your neck. 4) If you feel a lot of pressure on your jaw, lower the height. 5) You may feel discomfort when you start traction, this is normal. Once your neck gets used to the traction, the discomfort will lessen or disappear. Cervical traction device, adjustable cervical traction device with 3 types of powered traction and 8 built-in airbag supports, relieves and relaxes neck pain Neck traction device has 5 levels of adjustable settings. Designed for normal cervical intervertebral height, just turn the side knob and rear knob to adjust the height and tightness, producing a gentle stretch. Each adjustment will automatically obtain synchronized and balanced traction, achieving optimal spinal alignment while preventing Hyperstretch of the cervical spine.

After inflating, the pulling and pushing forces produced by the vertical air pressure on the cervical spine will evenly stretch the neck muscles and provide a 26 correction angle to achieve better traction effect. Note that it will take time for your neck to adjust to the new curvature, so you may feel pain from the traction initially.
