I'm trying to find out what the average weight of one of the Hancock and Moore Executive chairs is. Does anyone know? I thinking about one of these 2812ST Hamilton Swivel-Tilt Chair http://hancockandmoore.com/product.asp?productid=1428 or 1584ST Royalist Swivel-Tilt Chair http://hancockandmoore.com/product.asp?productid=912. I'd like to try one out before I make the leap, but no one near me has any.
