I dont know about now, but back in the late 90's Sealy made 5 different quality mattresses. #1 being the cheapest and #5 being the best. We bought a bedroom set and bought the #4 mattress. Wife rotates or flips it about every 3 - 4 months and it's still just as firm as it was from day one. No sags or soft spots. She's kept a cover on it and like RC said, buy the topper separately.
