Wish it were a little higher, I agree with another reviewer that it doesn't work by itself for under your knees for sleeping on your back - need another pillow on top of it. Firmness is okay, not overly hard/firm, head sinks a little into it. Wish it were a bit higher and just a tad wider. For the price, compared to what I've seen shopping around, it's a good deal. I have it in a standard size pillow case with extra folded under the pillow, works fine. There is that "memory foam smell" to live with for a while, but it's not too bad. I was able to sleep on it the day it arrived without airing it out. Overall it is comfortable and I am keeping it! Also works as a pillow to put behind you when you sleep on your side and don't want to roll onto your back (to prevent snoring).
