Funny how sometimes the smallest changes make the biggest improvements. On occasion I suffer from allergies and neck strain from sitting in front of a computer all day. This pillow has been just the thing my bedding was missing. The specs say it's 6.5 inches high, but at its highest point, mine is about and 3/4 inches in case it matters to anyone. I haven't tried sleeping on just this, so I put my pillow on top of it and it's just the right amount of incline for me. I'm a side sleeper normally but with this pillow, sleeping on my back is also more comfortable. I've had it for just about 3 weeks now and have no complaints. Since I don't sleep on it directly, I can't imagine spot cleaning will be a problem, but the tag does say not to wash it and to only spot clean. Can't see how effective that would be - I'd be more likely to toss mine after a few years and just buy another one. How in the world do you spot clean foam? Seems the moisture would soak in and not clean up. But that's just my two cents. Very pleased.
