First, I will say that I really, really like these pillows. They are quite lofty, seem to be well made, and are holding their shape and thickness well so far (after a month). However, I must also say that I would not actually classify them as 'firm' since they sink down quite a bit under the weight of my head. Fortunately, the extra thickness compensates for their lack of traditional firmness, and actually provides nice support for my neck. I find that I'm sleeping much more soundly and waking up without any neck or back pain. I've gone through several different brands of pillows in the last couple of years (all of which cost more) and these are by far the closest to exactly what I was looking for. I also have high hopes that they will hold up much longer than the others... at least they're off to a good start!! All in all, I am very happy with them and feel the quality and value is great for the price.
