I purchased a lightly used Steelcase Gesture a few months ago. I had been using an Ikea Markus. It relieved all pain and discomfort I was feeling. I should have made the purchase sooner.
I've a Gesture at work and it makes me furious - every adjustment of the armrests is gone if i ever make contact with the desk, for example. Ok, this is not a problem with the Gesture alone, but i'd really rather have some way to lock the armrests into position after adjusting them.
Maybe my model year is different or I use my chair differently.
