What the ancient Greeks slept on and make them look like this?

What the ancient Greeks slept on and make them look like this? What Americans sleep on to look like this? And what the Japanese sleep on to look like this? Because when you sleep on your back on these American pillows for 12 hours a night, you're probably in this double chin position, which could cause you to mouth breathe and snore, which could really mess up your facial structure. And for you side sleepers, it doesn't get much better because there's this huge gap down here that's going to cause your neck to cave in overnight like this, which is probably why you wake up with neck pain. And so you try and put your hand under your pillow to get more support, but then you just wake up with a numb, tangly hand. And that's why side sleepers waking up with neck pain are getting rid of these American pillows and switching over to these Japanese cervical pillows. Because when you sleep on your back with these cervical pillows, it forces your chin upward, which is going to help with that mouth breathing and snoring. And over time, it's really going to help with that facial structure and jawline. And it's even good for you side sleepers because there's extra support right here, so your neck isn't going to cave in overnight. And it even has an arm slot, so now your hand won't wake up all numb and tangly. It's also made with super nice memory foam. It has a cooling cover for all you hot sleepers. And don't worry for all you clean freaks, because it actually comes with its own pillowcase that you can just take off and throw in the wash.
