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.

Assembly was simple! I've been using it for a month without any issues.

As someone who spends a lot of time sitting and designing, I can't recommend this company enough to anyone looking for a new chair. My old cheap chair was wrecking my back, even when I tried to maintain good posture. I ended up sitting in awkward positions just to feel comfortable. I never realized how much a firmer chair could make a difference. A friend recommended this brand, and after using my chair for over a year now, I can't imagine going back.
