I bought two weeks ago this cushion in a furniture store, it would evaluate here, however, because I have had very good experiences so far:
My old pillow, also an "Ergo-mix" was saggy. In addition, I recently put me on a new mattress, in their combination I got extreme neck tension with the old pillow.
I myself weigh 80 kg (+ - 1Kg) and would say of myself to have broad shoulders (:
I bought the pocket sprung mattress, which in the summer of 2014 at Aldi - gave South, it has the toughness 3. Along with this pillow, I can sleep on wonderful.
The foam inserts to vary the height I did not away. The pad is fixed on the left and right side of the foam softer in the middle. This guarantees indeed that the head is always in a straight extension to the spine (at least with my specifications). This is therefore my opinion is actually not a gimmick but a functional detail. The cover has a circumferential
air-permeable application that provides a good moisture exchange. The cushion in itself makes a very good and high-end impression in terms of workmanship. Well I rate the description on the packaging cushions, which is shown here in the product photos (graphic shoulder width / mattress hardness).
I recommend anyone interested cushions, various pillows in real or similar in a furniture store to look at and try out there also. The cushions are available in terms of height and hardness, as I have myself observed on site, large differences, which are not merely judge solely on the basis of a review on the internet. Whether one then buys the pillow on site or at Amazon, you can then decide depending on the price difference, etc. still.
