Comfy, not a cushion you sink into, but is firm and holds well for hours. Love the full tilting back and the removable cushions. Downside is that if you are tall, around 6' the chair is too short.

Easy to assemble. The lumbar cushion and neck pillow are filled with foam. Sitting is very comfortable, even for a long time (10 hours +).

I have been looking for a great office chair that was more than the standard desk chair and I came across Dxracer. They had a gamer's chair, designed for long hours sitting and playing. The chair looked fantastic with thoughtful additions to enhance the experience if sitting for long periods. This chair was good enough to sleep in! If you want an outstanding chair that you sit in for hours at a time, this is the chair to buy.
