The back fell apart after a couple of weeks of extremely inactive use after purchase. After that, it became clear how the mesh was attached - more than that . and would not have lasted. A week later, the plastic at the bottom of the seat burst. There is a chair of the same model ten years ago, it is in good condition. Conclusion, the model was spoiled by the manufacturer. You can't buy!

Pros: A normal model, which is quite comfortable for girls without signs of obesity :) Got cons: For such a price, it's stupid to look for flaws in a budget model.

Armrests of different heights. The right one is 2 cm higher. Apparently this is how it was intended. Many here write about it. It is necessary to choose based on the parameters of the table. I'm small, it holds me well. Wife 86 kg. The gas lift sags by about 5-8 cm. But the chair is positioned as a child, so that's fine. Pros below: Price. Pretty well done. There is an assembly video, all the parts are in place and that's good. Has cons: The back is located strongly behind, it is not adjustable

Has pros: 1) Good durability of the wheels (out of 20 seats, the wheels (partially) changed only on 2 seats in 2.5 years). 2) Not a high competitive price at the time of purchase, they took 2.5 years ago for 3100 in Hong Kong time. Cons below: We bought 20 CH-797 chairs for the office, after the warranty period (6 months) the problems started: 1) The main problem is the "gas lift" - it started to lower at 3-4 chairs after 7 months, at 6 more chairs after 13-14 months. and another 3-4 chairs aft

I am attaching photos from the site and those that are purchased. Armrests are different, wheels are pure white, no color inserts, and the lowering mechanism is different.
