Hi, I’ve owned and tried many thrones from cheap to expensive and they all wobble! Is there a way to stop the wobble? I’ve used rectangular shaped keyboard benches that don’t wobble but are not ideal. I currently own a Sonor 4000 series that I like bc it’s light and simple and has a round seat but it wobbles terribly, I also own an expensive Tama 1rst Chair that also wobbles albeit a little less but it has a bike seat and I need a round seat. I’ve scoured the internet for solutions but haven’t found any real advise other that duct tape (doesn’t work) or spot welding (not gonna do that). I may try a lab stool ... or maybe, hopefully one of you here will devulge the no wobble secret!
