For me, it is very low and very hard. I can't imagine it being used without a second thin pillow, that is.
I don't think it's worth 40€+

It lost its shape within the first few months.
It is not hard but average. For my standards.

Update: it couldn't cope when my neck pain flared up. I had to use my old pillow, over 5 years old, which worked just fine compared to this one.
So it loses another star because I bought it for my neck pain and not for any other reason.
It might work just fine for others.

I think that just the company's name alone is the best guarantee; personally, it turned out much better than I expected. Certainly, the memory foam technology absolutely helps in making it the pillow that adapts to the shape of the head, which is responsible for a comfortable and restful position not only for the head but, by extension, for the entire upper body. I think that for its price, and given that we are not talking about a company exclusively specializing in pillows, this firm and anatomical pillow is an excellent solution for anyone who cannot afford to turn to the purely specialized brands of anatomical pillows.

It helped me from the first night, I fall asleep immediately and without waking up in the middle of sleep feeling stiff. It helped me a lot with my neck pain, I wake up rested without stiffness and pain.

Very good, stable and ergonomic pillow.

Reduced rating for three issues:
First, the zipper of its cover has a large (and sharp!) pull tab, which woke you up during sleep!
The second issue is its large size, which made most of my pillowcases useless. It gives its dimensions, so check your pillowcases because you may need new ones.
And the third is that you can't find a second cover to put on the pillow when you have put the original one for washing. And for those of us who hang laundry outside, it's not always easy to do it on the same day in winter.

Nevertheless, I would buy it again.

I agree at first it may not be convenient, but in the end I have to say the best. I have a neck problem so I looked for a good company. And in terms of construction quality and feeling, it is excellent.

I have a problem with herniated discs in my neck and it made it worse. The shoulder-head height is not correct, it should be a little higher

Personally, it helped me a lot and it has nothing to do with the previous one I had. I can say I found my health in sleep.

I bought it because I have a problem with my neck and every day I woke up stiff and in pain. The first night I took it off because I couldn't sleep. I persisted because my own people who had seen results recommended it to me. Otherwise, I would have been disappointed. In two nights, I got used to it. Now I don't get stuck in bed. I don't wake up stiff anymore. I don't hurt. It's not a pillow to snuggle with! At first, it's "unfriendly". Although I wouldn't say it's hard. If you sleep on your stomach, it's not convenient. I, who sleep on my side and curled up, find it effective. I got the 12cm height. Someone taller than 1.70m or larger may need the taller one.
