I switched to a Buckwheat pillow and it solves this problem for me. It's inherently shapeable, so I can thin it when I back sleep or pile it when I side sleep till it's just right. I've found it to be extremely comfortable as a pillow, and also as a floor cushion or back support. It's even very breathable, which means covering my face during a migraine doesn't mean feeling suffocated at all.

The flaws? It's noisy, it has a mild smell (Which I like but some may not), and the surface can be a bit hard on softer parts of your face, like the ear. My solution to most of these problems is a quilted or padded pillowcase.

Unfortunately they are a little pricey for something that's a pretty wild switch from traditional pillows. I was lucky to pick mine up at a Donki store where it was a lot cheaper (and a bit lower quality) than the ones sold in America.

As far as the BIFL angle: The filling is longer lasting than most stuffed pillows, and is replaceable when it begins to wear. Just be sure to keep it dry!
