I like this thread.

I resisted the idea of using a knee pillow because it seemed like a hack that undermined the simplicity and elegance of a hammock. But I now realise how foolish it was to be hung up on an aesthetic ideal when a simple, cheap hack totally fixes calf-ridge problems. Hooray for hacks.

A BIG knee pillow also fixes numb heel problems for me. A smaller knee pillow doesn't, but still works for calf-ridge.

Thank you leiavoia.
