Great pillow, very high quality materials throughout. If you need head support without your pillow going flat after a few months this is the pillow for you.
I’m a side sleeper and kept having side neck and shoulder pain so I switched to the Hullo. Definitely better support and has improved my posture while I sleep by preventing my head from craning downward into my shoulder.
Should’ve bought the larger size but I couldn’t justify it for a pillow at the time, which is ironic because of how much we sleep. Will buy the larger size when I can afford to, the smallest size works just fine and will use when traveling.
