I want to try this.

Can you share any details about that "regular pillow?" Ideally an online link that will ship internationally, but failing that: Materials, thickness, density, really anything that might be relevant would be helpful.

Nothing magical, it's just the same as I was already buying for my head: a mid-range (~$50USD), standard-size, down pillow. I mostly buy them from Bed, Bath & Beyond but the nearby store closed I've used a variety of brands from other department stores over the years.
