Review on Computer chair Everprof Opera M office, upholstery: textile, color: gray by Mateusz Swierczynski ᠌

Different pros: The chair material is made of a very dense synthetic cloth. 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. Some cons: 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.
