Updated November 20, 2023

The Beautyrest Black L-Class Medium is one of 4 models in the L-Class. It's one of the lowest-priced Beautyrest Black mattresses, much more affordable than their top models. We've received and reviewed the mattress and we're sharing our feedback with you below:

Comfort Scale Rating

The L-Class Medium mattress has a medium-firm feel that we rate 4 on our 10 point Comfort Scale (a 1 is hard, 10 is softest.)  If you're looking for a firmer feeling of comfort that still feels pretty neutral you should consider this model. This level of softness is acceptable to most people, but if you like softer then you should consider other models.

Pressure Test Results

This is a new model so we haven't gotten a chance to pressure test it yet. We have the previous model's results displayed, which we expect to be fairly similar. There should be some improvement in the newer model though. 

We will update this review with the updated results when we have them. They are a good indication of the type of support and pressure relief provided by the mattress.

    This mattress has a traditional innerspring mattress construction and is built upon a Zoned T3 Pocketed Coil design.

    Yes! You can finance a Beautyrest Black L-Class mattress on US-Mattress with Synchrony HOME, Affirm, or Paypal.

Conclusion

The Black L-Class Medium mattress is one of the lowest-priced Beautyrest Black mattresses so it will appeal to a lot of people wanting luxury features for under $3,000.  Its medium comfort will provide pressure-relieving capabilities and properly align your spine by supporting your back correctly.

The L-Class Medium has the three key features that are in all Black mattresses; the T3 coil, BlackICE with Plant-Based Cooling Technology, and BeautyEdge support.  Unique to the L-Class Medium bed is the 1-1/2" of AirFeel Foam layered under 1/2" Beautyrest Gel Memory Foam.  Coupling these two materials provides a contouring feel along with responsiveness to keep the mattress supportive and gives it the intended medium comfort feel.  Along with the added features in the lineup, it makes this an attractive model to consider. First and foremost the cooling nature of the BlackICE material helps to keep the mattress cooler so you can sleep better.  

If you're looking for a better bed and have the extra budget to go upmarket then this is a great one to look at. I do recommend it to people who want a neutral comfort with a touch of firmness that works for most people with excellent pressure relief. It's one of the better Beautyrest Black L Class models.
