Hi everyone, could i please have your opinion on countertop chairs in an open concept kitchen ,dining, living room area.

Are the chairs for the countertop peninsula the same chair for the dining room table just a different size, are the legs the same and fabric the same.

The dining table sits at 72" that will have the ability to have a book matched extension added on each end for larger gatherings, this table will have U shaped legs one at either end in brushed nickel like the handles in the kitchen,
