Very sturdy and looks like a much more expensive sofa. my sister worked for Knoll back in the 70 and 80s and it reminds me of their furniture.
The first got damaged (before it got here) and customer service was great, contacted me immediately asked what I wanted to do, kept in touch every step of the way. 
The freight company could use some lessons in customer service, but that is no fault but the freight company.
The fabric is very nice, looks like a raw silk/ linen blend.  If you have cats....it will pull if they claw at it at all. And that is only the fault of my cats.
I really love it, and the price is awesome!
