I am quite large, so that the 15cm version probably fits very well. However, I can imagine the amount of people with narrow shoulders is too high to me. Then you would have to try the lower versions.
Now I just hope that the pillow is actually maintaining the shape and elasticity, then I would be very happy.
The remuneration smell of aloe vera softener (somehow cuddly) that cushion himself had even shortly after unpacking no perceptible odor for me.
The cushion is quite hard and had about 7 hours after unpacking the full size and was then perfectly elastic.
I now have almost everything to cushion through (water cushions, artificial fillings of all kinds, organic spring / down fillings, Bolsters etc., what the market offers so and this pillow has been really unsurpassed pleasant. Remains to be seen whether the comfort fades with time or other disadvantages open up.
Should you try it in any case.
