Luxurious Extra Firm Comfort With an Affordable Price Tag

by Jed Harrington

The Beautyrest Black L Class Extra Firm is the firmest model in the line and boasts many of the same benefits found in the top of the line but at a lower price, making it an excellent value for the extra firm mattress lover.

Extra Firm, And Some Initial Padding

With a Comfort Scale score of 2.5, the L Class Extra Firm certainly exemplifies the extra firm, dense comfort promised in the name. However, unlike many models that can be really stiff and rigid, this one has enough initial padding to also contour well to the lower back and provide some comfort.

Phenomenal Support

The T3 Pocketed Coil system incorporated in the Beautyrest Black is nothing short of remarkable. Made using three pieces of high carbon steel braided together, this system is at the top of the Beautyrest line and supplies superior contouring, dampened transfer of motion, and long term durability. This coil system is adjustable base friendly and easily compatible with all modern power foundations.

Reduced Heat Allows For More Rest

The BlackICE 4.0 system, which has been recently added to this collection, utilizes four cooling components working together to help you achieve cooler, deeper sleep.

Offers Durability and Pressure Relief

The layer of Beautyrest Gel Memory Foam contours to your particular curves and provides not only good pressure relief, but also impressive durability.

Searching for extra firm comfort? This is for you.

Its combination of initial pleasing comfort and an overall extra firm Comfort Scale score makes the Beautyrest Black L Class Extra Firm a smart choice for those who like extra firm comfort. Its combination of top of the line features and a more reasonable price point make it one of the top luxury extra firm mattresses on the market today.
