I have slept on wedge-style pillows for the last several years to help control my acid reflux. When I saw "memory foam" I decided to replace my old and fairly worn out wedge pillow with this one... big mistake. This is NOT a traditional wedge pillow since it doesn't tapper correctly. This pillow could be used for sitting up in bed or something of that nature but I am simply amazed that anyone can SLEEP on it. A traditional wedge pillow tappers down so that you sleep on an incline but not vertical. I used this pillow for 7 days before I gave up and order my same old wedge pillow I've used for years. The one star is for the pillow case it comes with - one of the nicest I have seen for wedge pillows. Overall, please be aware that this is a sharp triangle pillow (thus awful to sleep on) - not a wedge with a nice tapper/ incline.
