There are a lot of meditation seats and pillows out there. Zafus, and wooden structures of sorts, you name it.

What do you use?

What have you used, and how did that compare to what you are currently using?

Have you found some seats, pillows, cushions to be more effective for posture and prolonged sitting then others. If so, why?

What is the brand of the products you use if they have such, and where can they be purchased?

Anything else?
