Luxury Extra Firm Comfort Without the Massive Price Tag

by Jed Harrington

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

Extra Firm, with A Touch Of Initial Padding

With a comfort scale rating of 2.5 the L Class Extra Firm certainly hits the extra firm, dense comfort indicated in the name. However, unlike many mattresses that can feel extremely stiff and rigid, this one has enough intial padding to still contour well to the lower back and provide a bit of comfort.

Top of the line Support

The T3 Pocketed Coil system used in Beautyrest Black is nothing short of amazing. Made from 3 pieces of high carbon steel braided together, this system is the top of the Beautyrest line and offers superior contouring, motion transfer isolation and long term durability. This coil system is adjustable base friendly and compatable with all modern power foundations. \

More Sleep, Less Heat

The BlackICE 4.0 system, new to this collection, uses 4 cooling components working together to keep you sleeping cooler and deeper.

Pressure Relief and Durability

The layer of Beautyrest Gel Memory Foam contours to your unique shape and provides not only good pressure relief, but also excellent durability.

Love extra firm comforts? This is for you.

The combination of initial pleasing comfort, and overall extra firm comfort scale rating makes the Beautyrest Black L Class Extra Firm a great choice. It's combination of top of the line features and more affordable price make it one of the best luxury extra firm mattresses available today.

Great Mattress!
Great mattress once again, I have been a Beautyrest Black fan for many years. We love their mattress's comfort and ability to last years. The extra firm is perfect for us. Although my husband and I are vastly different heights and weights we manage to find that we are both very comfortable. I sleep on my back and also turn to each side. Never wake up sore or shoulder hurting as I have when traveling and in different much too hard beds. Definitely a winning choice.

Wife likes it so that's all that matters.
My wife likes it. That's the sole basis for this rating.

Looking for extra firm, look no further.
My significant other and I were looking for a higher-end king-sized mattress that was extra firm and we finally found the mattress that we have longed for. Both of us can't deal with softer mattresses as they aggravate our backs. US-Mattress had a great promotional deal and the mattress has brought a lot of back pain relief. Very happy with the purchase.

Best Simmons Mattress
Excellent Simmons mattress if you like an extra firm mattress. It is actually not too firm and not too soft. Perfect for lightweight back sleepers.

US mattress was great. Delivery company was impossible to get hold of. You were at their mercy, though they did do what they said. Just don't miss their phone calls and accept delivery when they schedule it.
