Review on Computer chair Everprof Opera M office, upholstery: textile, color: black by Agata Szwed ᠌

Some advantages: the chair material, which is often made of synthetic cloth, is very dense. When one is sitting in a relaxed position, the back does not become tired. Adjustments for height and tilt can be made to a satisfactory degree. Various disadvantages: After only two months of regular use, it started making an awful creaking sound. Even after taking everything apart and lubricating it, it's possible that it wouldn't have helped. It sounds like an antique wagon when it moves. Welding done well.
