We ordered two sets because we needed 3 chairs.  It will be handy to have the 4th on hand for those few times you need an extra seat or even a replacement.  They went together quite easily although we did have trouble getting the screws aligned into one of the legs yet it still seems sturdy enough.  Anyway, they are quite comfortable and look really good in the new kitchen.  I wish the backs were slightly higher for added comfort but the height works really well with the counter height island.
