My experience after 3 weeks use: The first few minutes with the pillows are great. I think it is ideal in order to lie in bed at night, maybe something to read and cuddle up to it. Since it has the ideal shape to to conform to the body and is really comfortable. Also for the sleep phase in my opinion very useful. Now comes the big but, but: The movements during the night while sleeping is the 7 simply no 7, but in the morning some twisted Something that at night even bother sometimes. If you would stay exactly in the typical Einschlafposition lie all night, the pillows would be the best thing on the market. If, however, a little restless sleeping and also once a reciprocating movement back and, the cushion deforms also. I woke up several times during the night because I had turned the pad so that it was no longer just nice spread, but was rather folded into U-shape and then had an unfavorable uncomfortable heap. Therefore me the pillow completely unconvinced. For the very high price but I would have expected something better. In another review, it was said, who has not the 100 euros which they should save up, because it's worth it - I can not agree. Who sometimes just can make money easy, for the pillow will be no great disappointment. But the product is really to save, could be a real disappointment, I do not advise this.
My conclusion: to sleep and cuddle super! For people who are in their sleep often only conditionally recommended to switch back and forth.
