Review: La almohada me resulta muy cómoda. Tengo problemas en el cuello y la puedo ajustar al nivel de dureza que me acomode. Es la segunda que compro, la primera me duró seis años hasta que presentó una pequeña fuga de agua.
Review: The pocket that can be filled with water allows one to control the height and firmness of the pillow while the very soft top filling provides comfort. I am a side sleeper but I believe it would be great for all. Obviously it is heavy and one must remove water before transporting. This is easily done, but measure the amount which is just right for you .

## Questions & Answers

**Q: Is this pillow safe?**
A: Depends on what you use it for. As a pillow it’s very safe.

**Q: I wake up with very shore neck and upper shoulders, does this pillow helps me with my issue. I have tried mypillow but didn't get any good result.**
A: We have great results. The secret to the Waterbase Pillow is that it allows for customizable support due to our Waterbase Technology. The right amount of water can take a few sleeps to find with some trial and error for your perfect comfort and support. The Water Pillow by Mediflow is clinically proven in a Johns Hopkins study to reduce neck pain and improve your quality of sleep.

**Q: How to these hold up if you have cats that lay on them? I'm afraid of their nails...**
A: They should be fine. There is a thick plastic bag (which holds the water) on the inside of the pillow and then "pillow " surrounds the bag. So they would have to have very long nails to get through...I would think. Its very sturdy to keep from leaking everywhere so I really cant see a cat's nails puncturing it.

**Q: Does the pillow or pillow case contain any type of latex?**
A: No this does not contain any type of Latex.

### ⭐⭐⭐⭐⭐ Review
*by E***Y on 10 July 2020*

This pillow has helped me sleep comfortably with spinal degenerative disease. Aligns well, easy to find your preferred comfort level while adjusting water level. Price was great. Pillow has lasted a few years and is holding up great. Is very heavy when full of water.
