This sofa is by Cisco brothers LA.
This looks like a custom slipcover, but you may be interested in this piece that I spotted on eBay with similar lines: http://cgi.ebay.com/Slipcovered-Shelter-Arm-Sofa-Chair-And-Half-Ottoman-/250682841548?pt=Sofas_Loveseats_Chaises&var=&hash=item800f5c1126

covered sofa from Cisco Brothers, a custom made cocktail table and vintage sugar molds, give it a little bit of an industrial edge while keeping it comfortable.
