1. Quick Answer
The D-Core Cervical Pillow is a fiber-filled orthopedic pillow featuring a unique D-shaped center designed to cradle the head while providing firm neck support.

The D-Core is a specialized orthopedic pillow defined by its patented “D-shaped” center. Unlike traditional rectangular pillows, it uses high-resilience polyester fiberfill rather than memory foam or latex.

This pillow primarily targets back sleepers looking for structural support, though the raised side lobes are intended to accommodate occasional side sleeping.
