280011/ST IRON STOOLと280016/FR IRON STOOLの座面を取り付けるアイアン部分（①の赤丸内)ですが、商品によっては画像の様に取り付けた際、座面との間に隙間が生じてしまっている物があります。座面の傾き等にも関係しているので図②の280014/EL IRON STOOLと同様の物に仕様変更お願いできないでしょうか？
As for the iron part (within red circle of ①), which connects seats of 280011/ST IRON STOOL and 280016/FR IRON STOOL, some items have gaps between them as per images. It must relate with the degree of inclination of seats. Therefore, I would like to ask you to change it into the same specification as 280014/EL IRON STOOL of figure ②. Will you accept it?
