Has anyone ever bought a mattress from Jamestown Mattress place in Henrietta?

Full disclosure: I'm not looking to buy a new mattress. But something about this place that makes me wonder whether it's legit or not. I must have passed it hundreds of times. I don't recall ever seeing a single car/customer outside/inside at any time of the day/week (with the exception of the owner's? purple car, if I'm not mistaken). They air the same commercial (usually during Wheel of Fortune) for what seems like decades now. My wife and I made the exact same comment last night that the place must be a front for something. Otherwise, how in the world do they stay in business?
