Review on Ergousit Ergonomic Cushion Support Executive Furniture by Brandon Mix

My keyboard is under the table. The lowest the chair can go is a little too high for my forearms to stay straight. I used different casters than the ones that came with the chair to avoid possible marks on the wooden floors in my office. I wasn't sure if the included casters are made of material that doesn't leave marks on the floor. The instructions call for the use of an iron spacer (supplied). Others call them "Puck". LOL Another thing I want to mention after using this chair for a while is that the seat padding is not that good (too soft) and not very comfortable to sit on for a long time.
