I had surgery 2/8/13. I plan to go back to work on 2/20/13. Should I get an ergonomic kneeling chair for my office? Will that help with my BBL & TT? I want to be as comfortable as possible but at the same time I don't want to sit on my new behind just yet AND I don't want to sit upright because of the recent tummy tuck. Any suggestions would be greatly appreciated!
