These were really beautiful stools and wonderfully made. However I sent them back. 
1. Like many curve backed stools, the backrest is at such an obtuse angle it’s virtually impossible to sit back and upright in it. You end up sitting at a very awkward angle. Basically there is no back support at all with this stool.
2. The seat was very comfortable but short for bigger people. My husband is 6’2” , 209 lbs body-builder and the seat portion of it was simply too small for him. 

I was kind of sad because I loved the color and quality of these. They just didn’t work.
