The Beautyrest Black L-Class Medium is one of 4 models in the L-Class. At $2,599, it's one of the lowest-priced Beautyrest Black mattresses, much lower 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 5 on our 10 point Comfort Scale (a 1 is hard, 10 is softest.)  If you're looking for a firmer feeling of comfort you should consider this model.  A medium feel mattress is acceptable to most people, but if you like softer then you should consider other models.

Pressure Test Results

We've pressure tested The L-Class Medium mattress with petite, average, and large body size people on their side and back sleeping positions to see what kind of support and comfort you can expect. (Learn how we test.) 

This mattress performed extremely well during our pressure testing, earning 4 out of 6 'recommended' scores for its ability to relieve peak pressure points and provide adequate back support.  Pressure point relief makes the difference between a great night of quality REM sleep and waking up cursing your mattress for making your limbs numb. 

You definitely need proper back support for spinal alignment, as well.  When you sleep with your spine out of alignment your back gets tight and you can wake up in pain.  This mattress does a great job of aligning your spine correctly and relieving those annoying pressure points.

The pressure test results for this mattress are not yet available but it will be available soon.  Below is just an example.

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 3 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 can be one to look at, I do recommend it to people who want added comfort that works for most people with excellent pressure relief. It's one of the better Beautyrest Black L Class models.
