Bests & Worsts Reviews from Amazon

So I decided to try this pillow in my hunt to find the "perfect" sleeping experience. I've gotten it down to a science now. Unfortunately everyone's physiology is different. Different body shapes, different heights, different bone densities, different musculatures, etc. So no one answer will work for everyone. This pillow has a gimmick. That gimmick is to try and use a water bladder inside to add a firm bottom to an otherwise soft and puffy pillow, but with at least some "give" for the purposes of comfort. This is key, because some people tolerate certain pillows differently than others. My neck does not like a pillow that's too firm; my head does not like a pillow that's too soft. I've tried them all: feather/down, cloth, buck, memory foam...none of them seem to make much difference. I do have a pillow I bought on here ages-odd ago...Sleep Better Iso-Cool Memory Foam Pillow, Gusseted Side Sleeper, which is actually the most comfortable that I have ever used, primarily for its heat absorption capabilities. However it's too thin. I'm forced to add a more firm pillow underneath it so that my head doesn't sink down and cause pressure one way or another on my neck. In comes the Mediflow. In theory, the water bladder should suffice as an alternative to this quandry by adding the firmness layer. In concept it seems like a good idea, but it's not well executed, and most of it has to do with the construction of the pillow itself. The fiber is not the best choice to have for the top of the pillow, because you sink way too far in. The bladder is not big enough to offset this, it's a fairly thin layer across the bottom of the pillow even if you go to the maximum fill. The bladder is just not big enough. It really should occupy at least half of the pillow in order for the fiber not to sink your head too far down. If they combined the materialin the Iso-Cool with the bladder of this one, you might actually have a great product, but as it is, this one sinks (pun intended). TO put it in perspective, I slept on this pillow two nights in a row. The first day I woke up with a stiff neck. I assumed my neck was adjusting to the new pillow. The second day I was in absolute pain, having to rub my neck almost every 30 minutes because it just hurt so bad. I then put the Mediflow on top of my old trusty firm pillow last night. Today I have no pain, which seems to indicate my theory is accurate - it needs more bladder and less fiber to balance things out. There's not enough firm and too much soft, in other words. I want to caveat my review by stating that I am a side sleeper. I can sleep on my back but it's not comfortable at all. If I do it's because I rolled there from a side position just before waking up. Side sleep is the most comfortable for me, and this pillow doesn't make it work for side sleepers. Basically, if you use two pillows, this pillow won't replace both. You're likely to need a firm one under this one, then it might work for you. If you prefer firmer pillows, this pillow will fail you. If you prefer soft pillows this pillow will do you just fine, but then you defeat the purpose of buying it (the waterbase). If you're a side sleeper I don't recommend this pillow without a firm one underneath.
