I've noticed a lot of reviewers deducting a star due to the price, so I'm deducting 4 stars as I just discovered that the pillow costs £46 on the Mimos own website while I paid £63 on amazon. I also find it suspicious that the packaging is inconsistent - I ordered two pillows, one in size L and one in size XL, as well as the cover, and there were several spelling mistakes, typos and other mistakes on the packaging. As for the product itself I have no complaints. I can't say if it works or not, as my daughter doesn't have a flat head, I bought the pillow as a preventive measure, but I feel safe in the knowledge that she can sleep on it at night without danger of suffocation (we haven't tried this yet), and hopefully she won't develop a flat head. All in all I probably would have left a positive review if I hadn't felt so cheated on the price!
