The truthful answers is: "It's the thickness you are willing to pay for". One manufacturer I know of makes memory foam mattresses in three configurations: The top 2" of the mattress is memory foam, the top 4" is memory foam, and the whole mattress is memory foam. The price varies accordingly. Personal Note: If you can't afford a memory foam mattress, try a memory foam pillow. Awesome, especially if you're a "side sleeper".
