For dimensions, as has already been mentioned, it does not 60X40, but 57x36
Satisfied with the purchase, but now to be seen in time.
EDIT:
Well, it's been one month now that I use.
At first, it was actually a bit hard when the foam had reached its maximum penetration, and first nights, frankly, I hesitated to highlight my old pillow.
I even had a headache because of it.
It was curious, this unpleasant feeling of hardness (I did not notice right away!). Is it the pillow that has "done" or me who got used? In any case I no longer feel the sensation of hardness and this is happiness! In the evening, going to bed, I like to wallow in this pillow. So I added a star!
