Jonathan Stevens Mattress Co started in 1945 with the idea that by manufacturing mattresses in our own factory in West Michigan and selling them in our own stores, we could offer the public a better mattress at a better price for a better night's sleep. 66 years later, we are still doing that! 3580 28th St., SE - Just west of East Paris.
