Design Claims & How It’s Supposed to Work
The philosophy behind the Arc4life Cervical Linear Traction Neck Pillow centers on two distinct zones:
- The Traction Side: One side of the pillow features a V-shaped indentation. This is designed for back sleepers, aiming to provide a gentle pull (traction) on the neck to maintain the natural curve of the cervical spine.
- The Support Side: The opposite side is often firmer and higher, intended to support the neck and head for side sleepers, preventing the “collapse” of the shoulder that often leads to morning soreness.
By providing these two zones, the brand claims to offer better pressure distribution than a standard down or foam pillow. Unlike the Derila Ergo Pillow, which relies on the heat-reactive properties of foam to mold to your shape, the Arc4life uses its physical geometry to guide your head into a specific alignment.
