This chair is amazing!  It is soft, comfortable and has a great lumbar support.  It is also adjustable for height, so it fits each individual.  It rolls very easily (I do have carpet, so I have a plastic carpet mat under it) and the arm rests are comfortable as well.  The shipping was expedient and it was very well packed in its box.  My box was damaged in shipping, but the chair arrived intact and in great shape.  I would definitely recommend this product.
