Zen, thank you for making me laugh AGAIN today.
Honest, Michelle, preferences vary so much that it's hard to recommend. Some people like lots of padding. I find that thick padding makes me much more UNcomfortable. I think everyone goes through trying to sort this out, and the only way seems to be to try several different kinds/thicknesses of padding and see what works for you.
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
