I suffer from lower back pain (mainly due to an elongated tail bone) and have not found a good office chair.
I'm considering a drum throne (this guy here: http://www.aheaddrumsticks.com/drum-thrones-spg-bbr.html). Does anyone have experience with using a drum throne? Or can you recommend a good tail bone friendly chair?
I'm hooked on Ikea stools/chairs for work. My back just can't deal with those mushy OSHA-compliant office chairs. My recommendation would be to head to your nearest Ikea and try them all out.
The other thing that really helped my back pain was getting some Alexander Technique lessons from an experienced teacher. YMMV, of course.
You may wish to consider a standing desk. I’ve been standing dealing for about 3 years and love it. I have a hard ikea tall chair for the times I do want a short sit.
I’ve also recently switched to minimalist “barefoot” shoes. They made a huge difference to my knees. Maybe they will help your back.
I've been wearing the "barefoot" shoes for a few years and love them! I tried a standing desk for awhile and had mixed results.
My plan is a good chair + regular breaks + fidgeting. I just got a Simply Fit Board that I keep under my desk. I rest my feet on it and occasionally use it like I'm playing a double bass drum, then balancing on it during phone calls/meetings.
