Serta is the one to go with. We got a new frame, added "bunky boards" (thin fabric covered frame-needed 2 for a king size bed) resting on the slats that supports the mattress like a platform bed and allows for tucking in the blankets. No box spring needed.
The bed is not too high off the floor. You don't have to flip or rotate the mattress and it has been comfortable for years now. The mattress is the kind where when one of you moves around the other doesn't feel it at all. Great.
