Your current mattress has very little to no memory foam in it, which is why it held up well for so long.
Today’s Beautyrest mattresses are upholstered with memory foam.
When buying a Beautyrest today, you need a latex topper to go on it to insulate you from the memory foam.
The comfort designation of Plush/Firm was changed to Medium Firm.
