Fiber: The First & Original Water Pillow, clinically Proven to Reduce Neck Pain & Improve Sleep. Therapeutic, Ideal for People Looking for Proper Neck Support

In the past year, I realized that I was having back and neck pain due to my pillow. I'm in my late 20's, and have never had this problem before. I've gone thru a lot of pillows recently. I started out trying traditional pillows from target for side sleepers/back sleepers and just getting a new one every 2 months or so when it got too squished down for me.The last one I tried was the Homedics HMP-TRCL Temp-Rite 4 Lb. Density Classic Pillow, and I was really hoping it was "the one" -- I'm starting to feel like the goldilocks of pillows. It wasn't and my neck pain upon waking got worse. It was a great pillow until it squished down with body warmth and left you with no neck support. So..on to the next! I saw this water pillow as the #1 of the top 'popular' pillows recommended in an online news story. I was willing to give away my first born(ok, so I don't plan on having any kids, but I figured I could promise it despite that, right?) for a good nights sleep, so I ordered the mediflow water pillow.When it arrived -- I was like 'huh, this seems like a normal cheap pillow' with just the puffy fill, no feathers or anything. Then I started putting water in. The bottom of the pillow is the water pouch, where the entire top is the actual pillow. All in all, I wasn't overly impressed, but like I said before, I'll try anything. And yes, this sucker is heavy.Usually my first night with a new pillow is extremely uncomfortable, with this one, I actually slept thru the night. I did need to adjust the water a little, I had filled it to the brim, and took out just a cup or two. I think I'm in the firm category that they mention on the instructions. I also added the McKenzie® Cervical Roll Neck Support which I found here on Amazon. It adds to the firm neck support, which is just what I needed. Together, it's the perfect match for me.Now for the MAGIC: this week I've been waking up an hour or two earlier. And feeling...awake. not groggy and in pain. I think this might be the pillow. Because I'm sleeping soundly throughout the night, I reach my sleep limit earlier. I don't use an alarm clock, so I just get up whenever I naturally wake up(I work from home), which is usually 8:30. I've been waking up at 6:30 and then figuring I can squeeze in another hour, so I go back to sleep till 7:30.I'm so happy with this pillow right now, and for 35 bucks, it was definitely worth a shot!! If you're having neck and back pain, I know you're at the brink like I was. Don't bother promising your first born(or 2nd or 3rd) to anyone, just buy this pillow. =)

EDITED: After reading about 10 recent reviews I had to edit this one.It is NOT HEAVY.. Actually if you ever had a FIRM Down Pillow I would say the weight is about the same.Swing it around in a pillow fight. Why would you want to do that to a GOOD Pillow that is for sleeping. Want to pillow fight have another polyester or down pillow on bed for that.Propping up in bed. As one reviewer said, Have a couple of NON SLEEP pillows on bed for that. Although I do not find this pillow to be that heavy I would not abuse it by using it for propping.The pillow kept its height and shape all night and look pretty much like it did before I slept on it. I found that I did not have to sleep with my hand under it to prop my head up. My head rested on it as it should and wrapped around my neck supporting my neck. I find to get full support you must make sure the bottom of it is above your shoulders and not under them.Bottom Line, every one has an opinion and knows what works for them and their sleep problems. I do not see this pillow leaking in the near future if treated well. I am a back, side and stomach sleeper and it worked well with any position I was in last night. Great head and neck support and just what it is supposed to do.ORIGINAL Review: I got the product yesterday and could not wait to use it last night. Been waking up in the morning for months with stiff neck and terrible headaches. Although my neck is still a little stiff it is not as stiff as sleeping with out the pillow and headache is gone... I really do feel alot better and more able to face the world this morning. i filled it to medium but think that I might try the firm in a week or so .i slept on a waterbed for years and loved it . But can't risk putting it in the trailer I am living in now. Will definitely assemble it once I finish my Wood frame house. There is just nothing better for a good rest than a waterbed. Would always recommend that there be a regular bed in the spare room for anything but sleep, If you get my drift.Again this pillow is great and i anticipate my neck and headache to disappear soon.Only thing I could recommend to make this pillow 100% perfect is to do the filling with wool instead of polyester fiber polyester fibers do not hold up as well and do not breathes.. Wool breathes and stay cooler than anything else. They say that you can wash and dry the pillow (minus the water, LOL) but I would not recommend that.. I got a pillow protector and with the added pillow case you should have a great feeling and looking pillow for years to come.
