Hi zen4life,
Sleepmaster is the only factory direct manufacturer I’m aware of in and around Syracuse and they are included in the Syracuse list in post #2 here.
Sleepmaster is an independent factory direct manufacturer that makes their own line of mattresses named after local communities and they also make Bemco mattress (which is more of a licensed name) and WJ Southard. They make other “house brand” mattresses as well. They are an actual manufacturer and like most independent factory direct manufacturers … their materials, quality, and value are better than most of the choices you would otherwise encounter.
There is more feedback about them in post #9 here and a forum search on Sleepmaster or on Southard (you can just click the links) will also bring up more comments and feedback about them as well.
