For some time I was suffering from cervical spondylosis on waking; Ergonomic my pillow was too old probably. I bought the original Tempur and pain have subsided. Evidence of its effectiveness and comfort. While the first two nights were a little tricky because you have to adapt to this new material but I'm happy with this investment. As for the price, it is very interesting; Indeed, I went to a dealer of the brand and the listed price was higher than 40 euros !!
