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 ordered this chair last Month, it came earlier before the date stated on the website, so really happy and surprised at the extremely quick service. Put it together so quickly on my own. Extremely comfortable so hopefully my long days on the computer will be so much easier on my body.

This chair is nice and fun. Best chair for gaming and working. I recommend it!
