I need to buy a king-sized mattress and am looking at the Sealy Posturepedic Springfree which is a latex mattress at $1700 or the Comforpedic which is a memory foam for $3800.   I currently have a queen Comforpedic which I love but we didn't pay anywhere near the $3800 at the time and I'm having a very hard time even contemplating spending this much money on another Comforpedic.  With that said, does anyone know anything about the Posturepedic Springfree?
