Unfortunately, while I'm a big fan of browsing for furniture online, I wouldn't buy anything more substantial than a bookshelf online. I don't buy furniture terribly often, so when I do, I look for things that are going to last and that I won't regret in six months. Consequently, I like to see/touch the fabric, look at the stitching, and generally take a good look before I make a buying decision. So, while I'd traffic your site, I don't think you'd ever make any money off of me. I'm not one to tweet out links to products on shopping sites, or even like many things on Facebook, so to top it off, I'd be a viral dud. :)
However, I'm just one perspective and I may not be your target, so don't put extraordinary amounts of faith in my opinion. Congratulations for going this far, plus front paging Hacker News, and best of luck with your idea!
