Hi David, I also contacted you via Yelp.  I have a large sofa I need removed and taken to the dump.  Movers were unable to get it out of my flat for the Recology pickup.  Whatever disassembly is easiest for you — including a chain saw down the middle.  I am interested in you because I suspect I’ll have issues getting my new sofa inside the flat, and it may need some disassembly.  It’s still being made.  I’m in Noe Valley on Dolores between 25th and Jersey.  Thanks so much!  Terri
