This headrest is very soft and easily washable. Color is handy when the baby's sex remained a surprise. Given the size of the "hole" inside, I thought I would use it mainly for baby's first days but after several months, it is still topical. It serves mainly to reassure baby that has less tendency to roll his head at night but especially to ensure a beautiful round head, despite the hours and hours spent lying in the same position. The hair is also less "shredded" by the friction with the mattress. Remain honest: technology "shape memory" does not seem to me essential. I bought more classical that were nicely. But since I took advantage for me, I could not see myself at least offer my baby! ps: remember to buy two: one for the bed and one for the pram / pushchair. So, if there bavouse, sweating or regurgitation (yes, a baby is glamorous!), You have an exchange during washing.
