I know many of you will complain about this product's high price, and I cannot blame you. However, purchasing a good piece of furniture, a chair in this case, is a purchase you will only make occasionally. A good chair can last for many years without any issues, and on top of that, it will help you avoid health issues from the wrong posture during long hours of computing or gaming. In our lab, we have many chairs of this brand, with one of them used for more than six years daily, and it still looks like new! Its shape hasn't changed, and its mechanisms still operate flawlessly. If this doesn't demonstrate high quality, then what does?
The only problem, which is primarily personal, and this is why I didn't include it in the cons section, is that the seat of this chair is too hard for my taste. I prefer softer seats but others in the lab choose harder seats. For prolonged hours a tougher/harder seat material might be better, but you should always keep in mind that after 30 or 60 minutes of sitting in front of the PC, depending on the person, you should get up and take a short walk. This will vastly improve your health!
As for the noblechairs, Hero ST is a fine chair, especially if you prefer hard sitting areas. If you don't, then you should look at another model of this brand. Lastly, I would like to see an integrated leg support cushion and a noblechairs chair fabricated entirely from mesh.
