I've needed a new chair for a long time. The original chair I used in my office broke. Broke as in I leaned back, a spring shot across the room, and I nearly ended up on the floor. I then started using a hand-me-down chair, from my wife. It was a marginal chair at best, and was somewhere between 10-15 years old.
Within a few months the back broke out of that, and I was left with a stool. A few months after that, I received the Trey Chair. Finally having a good chair (the Trey) made me realize that my poor seating arrangement was responsible for my resurgence in chronic back pain.
I first saw info on the Trey Chair at Gizmodo, in early May of last year. During the summer I started looking for a new chair at my local big box office supply stores, with no luck. This past September, I contacted the folks at Trey Chair, and they were nice enough to send me a chair for review.
