    Perfect fit between your legs!

    I'm 6'2" 220 and thought this might be too small. Nope just right and thought reading others too hard. Nope just firm enough to separate knees. Love the case to keep it clean when not in use.

    It worked--no more lower back and knee pain

    I was very skeptical this would work to alleviate my lower back and knee pain when I moved from one position to another while in bed. It worked and my pain went away after the second night! Having a big block of foam between my knees isn't the most comfortable thing to have but I am now used to it and so thrilled to not have the pain anymore. I would definitely suggest trying it if the doctor recommends it, like mine did.



    I can only compare it to the Contour one -- this is one is much denser, and slightly shorter. It does not compress much between your legs, so it holds your upper leg more in a straight line with your hip. The other ones turn to mush in less than a year. This should hold up better. I think it will prove to be worth the higher price.

    Pain be gone!

    I have had terrible lower back pain and decided to try this after reading all the reviews. I can honestly say that this has alleviated my back pain totally, It is very soft, the cover comes off for washing, just the right firmness without squishing flat when using. Keeps those knees in the right position aligning the spine so the nerves do not get pinched while you sleep.

    Bottom really helps me sleep

    I've got constant pain in my left knee. This pillow is the perfect size, shape and density to allow me to sleep comfortably on my side. You'd think just shoving any old pillow between my knees would do the same thing, but this really works a lot better. Very glad I got it and well worth the money.
