While both pillows are adjustable to suit your body type, sleep position, and personal preference, they have a few differences between them:
Eden Pillow
Soft density for a luxurious, down-like feelContains gel-infused fill for a comfortable, cooling effect while you sleepThe outer case features a gusseted edge to prevent pillow pinch (when the edges of your pillow slope together and fill gets pushed out from under your neck) and promote a more even surface.
Original Pillow
Medium firm density for a balance between support and comfortContains a blend of memory foam and microfiber
