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

Absolutely amazing! Comfortable, great quality and didn't take long to put together!

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.
