Ergonomic Pillow

The original bamboo-cotton pillow with adjustable height and firmness 

  • It is worth the price especially if you have long hair

    The pillowcases are extremely well made, the seams are of high quality, and the fabric is exceptionally soft. I was dubious about the price before receiving it because 60 € per pillowcase is still high, but it is well worth it. Especially if you have long, tangled, or frizzy hair. I highly recommend it! 




  • Sublime quality. It delivers its promises 

    The pillowcase is very soft and pleasant to the touch. The quality is excellent with perfect seams and finishes

  • It worked great for my baby 

    My two year old daughter has curly hair that is very difficult to detangle. I chose this pillowcase to preserve her beautiful curls and frankly I do not regret my choice. Her hair is easier to detangle and her curls are perfect when she wakes up. Top quality product with great packaging! 




  • Lots of benefits. It is really good!

    Since I started using this pillowcase, I notice less frizz, less oily hair effect, and fewer knots when I wake up in the morning. My skin no longer has a burning sensation. I sleep well because it is soft
