Specs say can hold 30 kgs but for 4.5 kg keyboard only stand wobbles a lot. Without anything placed on stand still not firmly balanced, old stock was sent i can say as it was full of dust & shaky, might be defective piece too, couldn't replace/return because for return we need to take some print outs of labels & we were affected by covid. Better to buy double braced stands even if any keyboard is less weight, those would be much stable.
