I just had a round table custom made for my kitchen eating area. It measures 66" on a single pedestal. Looking to purchase 6 chairs in a leather finish. The ones I'm looking at measure 24" wide (each chair) They are a rounded back (similar to those in photo). I'm concerned that they may be too big or bulky. is there a rule on how many chairs should fit around a certain sized table? Any other suggestions would be appreciated. Alternative chair is the Avita chair from ferretti interiors - it is much more slim.
