I highly recommend that you check-out Fifthroom.com if you’re interested in finding Pennsylvania made and 
U.S. made outdoor furniture, garden structures, indoor furniture and home storage products. Many of the products are made by Pennsylvania artisans – almost all are wood. What I like about the website is that it represents several websites/retailers coming together to offer a single integrated website to sell their wares. You don’t see these types of endeavors enough and I think they are great way for smaller retailers to take on the big box retailers. As a FYI, I don’t have a beef with large box retailers, but as a rule, they don’t do nearly as much for the regional economy.
Fifthroom was started by Tim McTighe who began as a small retailer called Cedar Stores in the Pittsburgh suburbs.
