Just bought a new king set from a local mattress outlet in Florida. I had reservations buying from an outlet, but honestly the salesman knew more about the products there than at any furniture store we shopped. My biggest concern came when I could find no way to rate or review this mattress online before we bought. Sealy seems to have a different style for every type of store they put their product into. The mattress style is SHETLAND
I'm sorry to be the one to tell you, that you don't have a warranty. Mattresses purchased from outlet stores are factory returns. The return could have been for some small cosmetic reason, or it could have been in someone's home and returned because it became defective. The store where you bought it would not know the reason. He only knows that he bought a truck load of salvage bedding for pennies on the dollar.
Sealy does not make a boxspring, like the one you described.
