I write a lot of reports and sit A LOT. I wanted to make the time I spend seated more "active". This does the trick. Very easy to put together (minutes, because we used an air compressor that we had) and I have been using it ever since. I still have to think about my posture (I have learned to slump on this thing when I am distracted!). I have attempted the few exercises that came with the chair--nothing earth shattering but it does remind you to re-engage your core. The size was perfect for my home office. I have a nice set of shelves and desk and I was afraid that a round, rubber chair would look tacky but all you see when you come into the room is the tip of the black frame--perfect!
I am very petite, so this chairs fits me well, but I'm certain it would not work for someone over 5'10" or so. I use it for my art work and it helps me balance and keep my back from straining. Love it.
