I had one of these pillows about 15 years ago that I loved. It eventually wore out, and I had to replace it with something else. Now, I've found this one on Walmart.com, and it is very similar to the original one I had. Compared to the original, the memory foam side seems thinner and slightly more firm, at least until you lay on it for a minute, then it softens up. It would be a good pillow for back sleepers and also side sleepers who have a small/medium body frame. As far as durability, time will tell. But, 4 months in, it is holding up well so far.
