Love my new chairs! 
As another purchaser commented when putting the chairs together don’t tighten the screws until they are all lined up and secure in the hole. It took me about an hour to put together each chair, (10 minutes do put it together and 50 minutes to stand up from sitting on the floor -)
They are comfortably firm and supportive and the arms although slightly rough at the rounded part have a very natural and tactile feel.
