Query: Tri-Core Pillow Gentle Support

I am writing about the Tri-Core Pillow (Gentle Support). I am a side sleeper. The pillow information should emphasize that it is designed primarily for back sleepers. It is not very comfortable for side sleeping. There is only a small section of the pillow to rest one's head on if sleeping on the side.The pillow seems pretty comfortable if I lie on my back, but I have to avoid the back position when I sleep, in order to avoid snoring and to avoid a tendency for sleep apnea.
