AUVON is best known for medical-grade pain relief devices, and the NI3663 inflatable neck stretcher follows that same approach. It’s designed to decompress the cervical spine without the bulk or cost of a clinical traction unit. The M size uses a triple-layer structure with a wider base and a smaller top section, which keeps your chin supported while your face stays free of pressure. The inflated inner diameter is generous enough to reduce neck compression during use.

The key difference here is the chin-up design. A high-density foam insert pushes your chin upward at a 15-degree angle, creating a gentle stretch along the vertebrae. In practice, this feels more targeted than a standard neck pillow. You inflate it to your preferred firmness, lie down, and let the angle do the work. It takes about 10 minutes to feel the tension release in your upper traps and the base of your skull.

One thing to note: the M size fits average adult necks, but if you have a thicker build, you may want to check the dimensions before buying. The foam insert stays supportive over time, but the inflation valve can be slightly stiff at first. For the price, it’s a straightforward tool that delivers consistent relief without needing a prescription or a trip to the clinic.
