Just Bought a Sealy Podturpedic Ultra Plush Mattress??

I just bought a Sealy Posturpedic Ultra Plush king sized mattress set from a "discount" mattress store and had a few questions.

It is a 2-sided mattress, but as far as I can tell Sealy hasn't made 2-sided home mattresses for a few years now. I was wondering whether or not Sealy does still make 2-sided mattresses for home use and/or when they did stop making them (to gauge the age of the mattress, itself). It has the, again from what I can tell from pics on the internet, "older" style label on the top side of the mattress which leads me to believe that it is an older, unsold mattress.

There is also the possibility that it is a mattress made for a hotel/motel that is 2-sided. It for sure is a real deal Sealy Ultra Plush pillow-top that is still in the plastic wrapping, but I can't find any evidence that supports Sealy making a 2-sided mattress any time recently because all of the models on their website say "no-flip" mattress.

Any help with this is greatly appreciated.
