Ergonomic ?

I got my first ergonomic pillow just now. Has been unsure of its benefits and may not be able to get used to it, therefore did not really go and get one. Anyway, finally decided to get one as it may get my stiff neck I got every morning.


The pillow is contoured with one side lower, the centre is concave, the other side higher. It was selling at $39 in IKEA. There is another one at $9.90 but just simple CMI. *Cannot make it*
