Pressure Test Results

The L-Class Plush mattress has been pressure tested 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 model demonstrated great pressure relief and excellent back support for all body sizes and sleep positions.  Earning 4 out of 6 'recommended' scores, the L-Class Plush showed that it can properly support most people's backs for correct spinal alignment and also relieve excess pressure on the hips and shoulders.  Pressure relief is particularly important for quality sleep because excess pressure will cause a person to roll around in bed trying to get comfortable which wakes them up for a terrible night's rest.  Spinal alignment is just as crucial because a lack of proper support will lead to lower back pain, neck stiffness, and a grumpy you the following day!

The Main Beautyrest Black L-Class Plush Features in Detail

Beautyrest Black L-Class Plush Mattress

  1. 1. BlackICE 4.0

    The L-Class Plush has BlackICE 4.0 cooling material on the top of the mattress to help cool your bed by dissipating excess body heat.  BlackICE is cool to the touch and you can feel it under your hand when you put it on a mattress.

  2. 2. Beautyrest Gel Memory Foam

    Gel memory foam has 2 important qualities.  First, it conforms to your body's curves.  Secondly, the gel feature means it can help pull heat away from your body to add to the temperature regulating capabilities of the bed.

  3. 3. T3 Pocketed Pocketed Coils

    Individually pocketed coils are best because each spring moves independently and delivers precise support from each coil. This coil is a 3 stage design meaning it's softer in the beginning when weight is put on it, and then it becomes firmer under the heavier weight.

Conclusion

The Black L-Class Plush mattress has an attractive price compared to the rest of the Beautyrest Black lineup, so that will make it popular.

It's rated a medium feeling comfort so it will be comfortable to most people, and whether you sleep on your back or on your side.  If you're a stomach sleeper you may want a firmer bed.  The pressure test results for this bed confirm that it's highly recommended for back sleepers and it performed fairly well for side sleepers, as well. 

This model is designed to help keep you from getting too hot.  It has BlackICE 4.0 material on top to help dissipate body heat.  And underneath it also has Gel Memory Foam to aid temperature management.  The innerspring support is provided by individually pocketed coils Beautyrest calls T3 design referencing the variable tension in the springs.  

This is a well-equipped model from a leading luxury brand.  Being it's one of their most affordable models, you can get a relative value with this particular bed.  It's also a medium feeling mattress so most people can't go wrong with this choice.
