I've been buying Sona pillows for years, the same type as the one I recently purchased. This shape of Sona pillow is the shape that works for me. When I started using it years ago I stopped snoring and waking up in the middle of the night gasping for breath. It's like the pillow is a life-saver, seeming to have cured my sleep apnea. I've told lots of people about it including my doctor.
