I ordered the medium comfort level, 39oz weighting, queen sized pillow. It responded and felt like a firm - the pillow barely sunk in when my head rested on it and the pillow felt more like a hotel firm than a hotel medium or soft. The firmness of the pillow positioned my neck crooked from my spine while sleeping, resulting in waking up throughout the night from neck pain and having a stiff and painful neck and upper back the next morning. I am proceeding with returning this pillow. 

For those who are looking for a firm and thick pillow, this might be suitable for you. The quality seemed good.
