It is indicated on the packaging that the material is shape memory. Personally I did not notice. Moreover, the purpose of this type of product is to keep so I do not see the point of a shape memory knowing that there already has a space for the baby's head.
Positives:
- Pleasant to the touch material
- The planned space allows good stall baby's head
- The shape of the pillow
Negative points:
- It is not removable so you had to wash it fully what can happen often when baby spits
- I would have preferred it to be a little less soft (there should be about 3cm thick barely
- Product difficult to use when the baby starts to move (about 3 months) because you can no longer lock its head. I do not see how it can be used up to 6 months unless you have a very quiet baby in his sleep
