VERY sturdy chair. Took me about half an hour to assemble. Much easier with someone else to help you.

Honestly, I was pleasantly surprised. The chair is more comfortable than I expected. It encourages you to sit upright while working but also allows you to relax a bit in a "less ergonomic" position when needed. Pros: The quality meets the expectations for a brand like this (and the price). The lumbar support is noticeable even in its lowest position, which helps improve posture. Things to consider: There aren't many downsides, unless you're very picky. The armrests feel slightly loose, though this is understandable given their range of motion. If you're not very heavy, the cushioning might feel a bit firm. Personal experience: I bought the XL version and initially doubted if it would be too big. However, it would have been a mistake to get the regular size, especially since I'm tall, have long legs, and am on the heavier side. So, it's really important to consider who will be using the chair before making a decision.

The wheels don't make any noise and so far don't scratch the floor. The headrest and backrest can be adjusted to the height you want, which is very useful if you spend a lot of time sitting in the chair.
