I had high hopes for these chairs because of favorable reviews.  I was sadly disappointed.   These chairs are the worst.  I ordered three and two of the backrest pieyes came with broken ceramic inserts.  If you plan on having anyone sit in these with nice clothing, make sure you thoroughly wipe down the ceramic inserts or you will have grout all over the back of your shirt.  DO NOT buy these chairs!  Spend the extra money on a decent chair.
