Very supportive for side sleepers that want the most firm option
I am a side sleeper and this is the first pillow I've found that is truly dense enough to use without having to fold it or try to bunch it up. It's very firm and supportive so if you are tall (broad shoulders) and a true side sleeper, this is the pillow for you. It's rare to find a down pillow that is truly filled enough like this to be very firm. Really seems nicely made and high quality. That being said, the pillow they make that is "medium" is more supportive than most down pillows, so start there if you roll around and sleep on your back and side.
