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

The chair came incredibly quickly. The back fits my shoulder very well and the base is soft but firm.

Impressed by the chair's quality. Above all I want to mention how nice the design is. I was doubting wether or not it would be worth it to get a design, as there's quite a premium on top of the base price, but a particular one stood out to me. Having purchased it, I do not regret a single cent. It's extremely well executed. I am really impressed by the effort that went into this. I am impressed by the quality of every part of the chair. It is a joy to use, it feels incredibly sturdy and comfortable, and with the amazing design. I think this chair is worth every cent that is asked. My only complaint is that the delivery service is impossible to deal with, as always.
