This product provides excellent support. Almost too much for me. It fits the curve of my back very well, though it seems to push me forward in my chair. The chair I use it on does have some lumbar support in itself, so that may have something to do with it. It is a sturdy, well-made model. My coworkers jokingly called it the "deluxe model" since it is very well made and large compared to the ones they use (mesh support or small wedge pillow) I like it most days, though sometimes I find it is just too much. In a chair with little or no support this would be excellent. I would not recommend this pillow for larger people, as the sides are formed and curve in toward my sides. I am a small-framed person; I think they would dig in the sides of a larger person making it uncomfortable. ..More
