I have a smaller kitchen island with two beautiful stools with backs that are on the larger side that is usually just right for my husband and I.  As everyone knows, when you have a get together everyone congregates in the kitchen for whatever reason.  I can now grab these two stools, angle them on each side of the island and at least accommodate two more people.  The fact that they stack they take up virtually no floor space when not in use.  Also they make a great step stool for 5' tall me!  And as far as I'm concerned, first come, first sit!!!
