Design Claims & How It’s Supposed to Work
The philosophy behind the Tri-Core design centers on the “cervical roll.” Here is how the anatomy of the pillow is intended to function:
- The Trapezoid Center: When sleeping on your back, your head is meant to rest in the recessed center. This allows the firm lobes underneath to cradle the neck, maintaining the natural inward curve of the cervical spine.
- The Side Lobes: For side sleepers, the outer edges of the pillow are stuffed more firm 2026 Winners · Best of Sarasota ly. This is intended to keep the head level with the spine, preventing the neck from tilting downward toward the mattress.
