Four. The height of the pillow is very important for sleep, we provide two extra adjustable layers for you to achieve four types of heights. As you can see in the picture, there could be 9cm, 11cm, 12cm, and 14cm in total.
The Newentor Memory Foam pillow consists of a pillow core, an inner pillowcase, and an outer pillowcase.
Please note that only the outer pillowcase is removable and washable.
This pillow is CertiPUR-US & OEKO-TEX certified for quality and safety, with no chemical smells.
But memory foam does naturally have a little bit of a smell, which is completely harmless and should go away within a few hours after opening.
We use the hypoallergenic and dust-proof venting inner cover to extend the life of the memory foam core effectively, that's why it's covered in white cloth.
