10 euros ... a joke it. In a positive sense. Because the pillow delivers what it promises. After four or five days of sleepless nights I sleep very well on it. But the unfortunate neck strain were from the outset no longer an issue. The memory foam works very well. And this is the beginning - if one is not used to and rotates a lot in his sleep, the problem. If you turn around from the back to the side, the pillow of the new situation must also adapt again only. It shows I was doing then first awake again.
But: Just a matter of habit.
Regarding the "chemical smell": When unpacking quite available and secure while sleeping only times nix. But I got the pillow also only times leave two days are open and that was enough.
A deduction gave it because the pillow on the left half a hand's breadth "dip" has. For 10 euros you can certainly not expect much and it is located at a point unproblematic. But still you can at least expect flawless goods .... due to the low price but still 4 stars
