The Beautyrest Black L Class Extra Firm is the firmest model in the line and comes with many of the same bells and whistles found in the top of the line but at a lower price, making it an excellent value for the extra firm mattress lover.
With a Comfort Scale rating of 2.5, the L Class Extra Firm certainly exemplifies the extra firm, dense comfort indicated in the name.
