Bought three and one broke when I sat in it. It was replaced. Then sat on again and two of them broke. Same issue. These are a new purchase. The chair spinner sits in two thin pieces of wood so if you sit on the stool the wood planks calapses. The spinner is metal. 

Second the seat back is screwed directly into the stool (wood against wood) the slightest lean back the wood will crack. 

Lastly, the wood footing has no protection. Bare wood. 

Beautiful stools visually. But cheaply made. ,
