Hello all, Namaste. I am wondering if any here uses any tools, specifically meditation stools/chairs. Some times, due to knee surgeries, I can't really sit on the ground very long and it really interrupts my sessions. I have tried sitting in a regular chair but for whatever reason it seems "wrong". I am looking into a few different seats/cushions and if you use anything like that, I would love to hear your thoughts, good or bad, on what you use. Thanks in advance.
