Love my new dining room chairs.  They look great with the nail head design.  The back doesn’t have any cushion and are just really fabric, but that didn’t bother me.   The seats are firm, as other reviewers have mentioned, but again, I was ok with how they feel.  I had only gotten 2 sets, but I am getting one more set to complete my look!  
The assembly wasn’t too bad, and once you got thru doing the first one, the second chair went easier....
