Before buying this pillow, I kept experiencing back pain whilst meditating. I read that raising the height of your seat can help with this. I decided to lash out and buy the Reehut meditation pillow and I'd never go back. I love it!!! AND it has really helped me to feel more comfortable during meditation, due to less lower back pain. It feels and looks to be a good quality product - so I am very happy!
This is my first Zafu/Meditation cushion. The buckwheat provides good stability, but is reasonably noisy if moving at all, but small issue. I get a numb leg when using the cushion, but it is more a structural issue with my body rather than the cushion itself. Even the small size (large one not available) seemed large enough and I'm 177cm and 90kg. Large would have been better, but it still works.
