I’ve tried a number of pillows over the years; cheap ones, expensive ones, latex foam ones.
All, even the “fancy” ones eventually just get lumps and I need to replace them. I tried foam because they wouldn’t end up with lumps but they don’t really hold my head in place and I feel my neck/shoulders tensing.
I’ve had insomnia (take 2-3 hours to fall asleep) for about 14 years.
It still take me a while to fall asleep but It’s been drastically improved with this pillow.
I sleep on my stomach and took out about half of the filling.
