Smooth rolling and transitioning chair. I use this in my office for my business and my art work. I don't feel any strain on my back hips or arms in this chair as I roll across my office and raise and lower the height to fit each desk station.
The chair is light comfortable and easy to build. The lift on the arms makes it easy to tuck away into your desk. Only downfall is that after a few hours it gets uncomfortable and hurts to sit in. A little more padding for the butt would be perfect.
As much as I wish this was as nice as the memory foam chairs from Serta...it is also less 1/2 the money. and at this price point it really is excellent. Solid feel and construction. I will note it is a little large...for those who might want something a little larger.
