I understand the Gokhale philosophy that we can make any chair work with a towel/wedge/stretchsit pad, but I'd like to buy some new chairs for my house, both living room chairs and outdoor patio chairs, and it would be wonderful to invest in some chairs that support good posture without any modification. I'm looking for comfortable chairs with armrests. I have gone to several showrooms and completely struck out. One of the most common problems is that the chairs are too deep to position my bottom all the way back in the chair (and I'm 5'10"). A chair that would allow extra room for one's hips to go all the way back (like a folding chair naturally does) would be a wonderful bonus. I am also interested in high-back chairs, in which one could rest their head on the back in a good position, as I find keeping my head from migrating forward is one of my biggest challenges, and the headrest is a wonderful reminder for positioning. In any case, any suggestions anyone has for chairs with these or other features that support good posture would be greatly appreciated!
