Multiple locations
With deep roots and several locations in Tucson, Sam Levitz is pretty Sam Legit. There's not much they don't have: mattresses, dining sets, office furniture, entertainment centers, barstools, couches. They don't have any Iron Thrones for display on the floor, but they offer so much else that they're likely to bring one out if you just ask them to check the back.
