This is what Singaporeans are sleeping on.

This is what Singaporeans are sleeping on, then your neck becomes like this compared to what the Japanese are sleeping on, which makes their neck look like this, super sharp and your jawline comes out. So many people are still sleeping on this kind of pillow, your neck is creating this double chin and it does not have support here. Even worse, if you're a side sleeper, there's a hole over here and you're going to have neck pain in the morning. That's why everyone is switching to this ergonomic pillow. Not only does it give me a nice jawline because it straightens my neck like that, when I turn to the side like this, this actually sticks out. It supports my neck so I don't wake up with neck pain in the morning. And for the usual pillow when you sleep, you put your hand underneath like that to try and give yourself more support, but it makes your hands so numb in the morning and loses blood circulation, whereas this one does not. It comes with this part that is cut out for you to rest your arm over here and it's made with this super cooling silky material, which is perfect for Singapore weather. You all can see there's a zipper over here, so this is how you can unzip it and wash the pillowcase. It also fits any regular size pillowcase as well. The only problem is that there's a lot of fake ones out there, so I'll put the link below to this same one that I'm actually using. And this one has the best reviews, but because everyone has been buying them, they're always out of stock. If you still see the link over here, go and grab them before they sell out again.
