The Tri-Core Cervical Pillow is an ergonomic sleep accessory designed specifically to support the head and neck. Unlike traditional rectangular pillows, it features a distinct trapezoid-shaped center and raised outer edges. While it is often discussed in the context of posture, it is important to clarify that this is a consumer product marketed for sleep comfort and is not a medical device intended to treat or cure clinical conditions.

| Trapezoid Center | Provides a dip for back sleepers to keep the head level with the spine. |

By utilizing fiber-fill instead of traditional down, the pillow aims to distribute pressure more evenly across the surface. The goal is to reduce “tossing and turning” by providing a stable base that doesn’t require constant fluffing throughout the night.
