This pillow is 3 inches in thinness, a little bit thicker than the above pillows but offers all the same comfort and safety.
It is a low profile memory foam pillow that will give enough support for your head, neck, and spine when you are sleeping on your back. It is embedded with a removable zippered cover made from cotton, a very comfortable-to-touch material, so you can freely put your face on it when sleeping on your stomach. There is no scratchy feeling on your cheeks. Some users review that you can also fold up this pillow to support your head when you sleep on one side at night, but we do not recommend it because the memory foam slab is responsive to pressure, it may bounce back and wake you up to change your position.
One thing that makes the Perfect Soft pillow different from the above pillows is that its memory foam has CertiPUR-US certified, which is a trustworthy guarantee that the pillow is safe from all kinds of dangerous chemicals to both humans and environment. It is hypoallergenic and has been confirmed on reducing neck and spine pain by many users. A very competitive brand for you to consider!
