Query: Eh...

Size, dimensions true to description. Serves its intended purposes .. for the first 1-2 weeks. Then, I suppose like all foam-type pillows, it begins to lose its shape and support. In less than 30 days (daily use) the wedge lost roughly half its size / height. Essentially it compressed. I still find some use of it, though now I have to 'supplement' its height by placing a regular pillow on top.Kind of defeats the purpose. I don't know that a reasonably comfortable foam wedge pillow exist that will maintain its shape for a lifetime. If one exist, it's not this one!
