Review on Computer chair Everprof Lotus S4 gaming, upholstery: textile, color: black/grey by Boyan Chukov ᠌

When the rolling spring's stiffness was adjusted, there was a clicking sound when landing on a chair. This sound was eliminated when the adjustment was made. When the spring is tightened, it is no longer visible; nevertheless, after some time has passed, it reappears. It is very frustrating. On the third day of using it, I stumbled into this "jamb." My wife assumed that I was rattling pans, but I can't add a video since it won't let me: - On the housing that conceals the mechanism for adjusting the backrest, the thread is crooked, and one of the screws does not want to go all the way in; - The metal used in the hardware is of very poor quality; during the assembling process, the slots on one of the screws were pulled out; - It has previously been mentioned by other users that it is required to alter the screws used for mounting the armrests in order to ensure that they do not protrude from the armrest itself; - A feeble instruction in which there is not a single word about securing the casings of the back adjustment mechanism (which is a trivial matter, since it is obvious where to place them). In general, it contains a greater quantity of information that is superfluous than is required; - The wheels in the cross make a rattling sound when rolling on the floor; - After one week of use, the screws on the backrest mount fell free. - The cross makes a rattling sound. There is a "sliding" mount on one side of the seat (as seen in the photo). There is a backlash there, which leads to a crooked back as a result (see photo), which has an effect that is not exactly favorable on the "even posture." I have no idea how many times I can "tighten" it until the slots on the screws are destroyed. - The zipper is closed in a crooked manner, it is not possible to open and shut it regularly, the cloth is too tight, but this is not an emergency situation; - The cover has a cracked seam.
