In another review for the medium density model of this pillow from this firm, I mention this firm density one. I purchased and kept both the medium and firm density pillows. First and foremost, I greatly prefer plain ordinary foam pillows over any of the down, synthetic down, down alternative pillows, and I have not found any of the newer memory foam, gel memory foam or other specially designed foam pillows that I liked. And I've tried many over the years. These pillows are however good to great. I found that this firm density pillow is a bit too firm for me for most nights, but on occasion when I want a very supportive pillow, I go right for this one. The main pillow I use almost every night is the medium density pillow by the same manufacturer through Overstock, and that pillow has been the perfect pillow for me. It is the 'Goldilocks solution" - not too soft; not too firm; just right. So if you're looking for a very firm pillow, this one is a good bet to try. If you you like a mix of good support and some 'give' then you might want to consider the medium density version.
