In general, it’s good, but the gas lift doesn’t pull on a quality product at all, I don’t know how to change it, send it to Hong Kong under warranty, or like no idea! Pros: Comfortable back, material is good, not leather is already good Cons: The gas lift is bad after 5 months, 90 kg does not keep falling forever, I suffer terribly with this. Fastens just everything that is possible after 2 weeks of use.
