## 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 C***M on 8 September 2024*

I bought this pillow on a whim at my kids' allergy doctor appointment. The office was shared with a chiropractor, and they were have a Christmas special: buy one, get one half off. The desk girls had personally not tried it, nor received any feedback on them. I took it home and tried the medium amount of water recommended. The next night, I tried the most water. The 3rd night the least. On the fourth night I added a little less than their recommended "minimum amount" and was SO SOLD on the product I went back to the doctor office and asked if they would sell me a 2nd at the half off deal. They did! Now I can roll over onto my husband's side of the bed and not get a crick in my neck. BEST INVESTMENT IN YEARS. I had been happy with a previous pillow but had washed it so many times I could not not read the label any more! Where did i buy it?? What brand was it?? I spent a stupid amount of money on over a dozen different types and thicknesses of pillows over the next 6 years and some would work for a short time before I would wake up with a sore neck that would last for DAYS with an accompanying headache. I, like other reviewers here, considered expensive diagnostic tests to figure out what was wrong with ME. Turns out it was just a pillow issue! I have had my pillow now for 6 years and just went on a trip to a humid area for 3 weeks and came back with mold on my pillow case- I shower at night and my hair was still damp in the mornings. I tried spraying the pillow with bleach, which helped but didn't remove the spots entirely. I had a spare in my closet (cuz I dread a possible night's sleep without one, should I ever need a replacement and find them all back ordered or something equally horrific!). I figured the washing machine was worth a shot- I could break out the spare replacement if I had to. The front loading washing machine tried for an hour to spin and drain the last 3 minutes of the cycle and I just finally gave up and let it finish air drying. Next morning I could see that it was a blob of pillow innards in a wad on one end of the case. Oh well! I pulled out the new replacement from the plastic bag in my closet and found that it had another name (panic! A quick check showed they were the same company though: previously "Floating Comfort" by Mediflow. Now just "Mediflow" was printed on the non-removable case), and it was WAY thicker-seeming than my wadded blob I was replacing. However, I now had no alternative (name any commercial, brand name, anchor store brand pillow and chances are I've tried it!) So I slept on it. All I can say is, I was unaware of my head/ neck while sleeping and I have been unaware of my head/ neck during the day all 3 days I have used it. Maybe my older version of the same pillow had just gotten compacted over the last few years of use? I don't know, but I'm coming on here to 1) buy my next replacement and 2) get the little case so maybe I can avoid the mold issue in the future. I literally take my pillow with me on all over night trips or else just anticipate a sore neck/ headache during my trip. Here were my initial concerns: 1) I didn't want to have to replace water weekly/ daily/ monthly -but GOOD NEWS! It only has to be replaced once a year! 2) I didn't want to have to go out and buy fancy water. The water where I live is very hard and even with a filter and softener system it destroys things in short order. But- I can just use water from the tap! No fancy distillation, filters or spring water required! Yay! Additionally, my daughter suddenly developed a sore neck when she turned 18. She was saving all her money up for college, but I told her she needed to spend some of her money on this pillow anyway. She finally broke down and bought it and was instantly glad that she did! So don't assume it's only for us 30-and 40-somethings (and beyond!) It can be beneficial for the younger crowd, too! I followed the directions- I have never had any issues with leaking, and the water level stays consistent until your yearly water swap!
