DO NOT BE LURED INTO BUYING THEM. Customer support is atrocious.

Purchased a set of four (4) Calligaris chairs, catalog number CS368. These are metal-framed, leather covered chairs. I was assured they were high quality Italian construction from a reputable company. Wrong!!
First problem. I ordered them in June 2007, I received the last chair at the end of November 2007. Why? The order was filled in Sep but one chair was damaged in shipment due to poor packing. That chair was then replaced with a wrong model chair 6 weeks later. I finally had the shipper write them in crayon to get the order straight and I received the last chair at the end of November 2007 (5 months).
Second problem. Had dinner guests over 2 weeks ago. One chair snapped apart - with the guest in it. Upon inspection of this broken chair it was obvious that the internal metal frame of the chair was attached to the vertical metal backing of the chair with a single 3mm spot weld. No bolts, no nothing else, just a 3mm spot weld. That would be about less than 1/8th of an inch for US folks. For a chair that costs nearly $1000 I could have done better with a 19.99 lawn chair from WalMart for constructional support.
Third problem. I immediately contacted Calligaris, Italy (head office) and Calligaris USA (point of purchase). I clearly identified the problem to both offices and clearly stated I require someone to 'immediately' contact me to set up a time/place to have the chairs inspected and have the broken chair replaced/repaired. This is important considering no one can used these chairs until I know they are safe to sit on. I can't inspect them myself without removing the leather covering to check the quality of construction and thereby ruining each chair in the process. To this day, 1 May, NO ONE from Calligaris has gotten back to me.
Caveat emptor when it comes to Calligaris folks
