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

This chair is much better for me for everything I do than other brands like Respawn and other competitor brands. I was able to sit in the respawn chair for very little time before experiencing pain in my bum bum. However, with this chair. I am able to sit for more than 5 hours at a time to stream, work, and game. This chairs reclining feature is also very robust and very stable. The arm rests can also be adjusted in a bunch of ways that can make it comfortable for almost anyone.

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.
