This model is the medium comfort of the CX Class hybrid models in the Beautyrest Black collection.  We've reviewed this bed's features and benefits, please read on for our expert review:

Comfort Scale Rating

The CX Class Medium mattress is rated a 5 on our 10 point Comfort Scale (a 1 is hard, 10 is softest).  Most people will find a mattress with this level of comfort very appealing.  However, if you feel that your comfort preference is a bed that is either much firmer or very soft then you may want to consider the other CX Class model (plush) with a different comfort level.

Pressure Test Results

We haven't yet tested the new version of this model, so these results are for the previous comparable mattress from the Beautyrest Black lineup (X-Class Medium). This is just an example of what the test results look like. We will update with the results once we test the CX-Class Medium.

The yellow areas in these images indicate where there's a rise in pressure above what is considered normal, or acceptable. What you really want to see are vast areas of green and light blue which means that the body is getting the exact amount of back support and pressure relief necessary for a good night's sleep. 

Your body needs proper back support for correct spinal alignment.  Without correct alignment, you'll likely experience head and neck pain, lower back discomfort, stiffness, and extreme weariness the next day all due to low-quality sleep from improper spinal alignment. Pressure relief in your mattress is just as important because excess pressure on your hips and shoulders can cause numb limbs which makes you roll around in bed to find a more comfortable position.

Beautyrest Black X-Class FAQs

1. Do I need to flip my Beautyrest Black X-Class mattress?
   

   No, Beautyrest Black X-Class beds are built from the ground up and are not designed to be flipped. This has become the new standard for mattresses today. It often means more comfort materials can be packed in. However, rotating it is still a good idea for getting even wear.

2. How is this X-Class mattress constructed?
   

   The Hybrid X-Class Collection has a traditional innerspring, the Zoned T3 Pocketed Coil, combined with multiple layers of memory foam which is what makes these beds a hybrid.

3. Can I finance my Beautyrest Black X-Class mattress?
   

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

Conclusion The Black Hybrid CX Class Medium mattress is a medium-feeling bed by Simmons.  This comfort is popular because it makes a great compromise for couples who have different sleep preferences.  There is another comfort level in the CX-Class models if you feel that something plush might be your preference though.   One of these mattresses' main features is the AirCool Memory Foam infused into the mattress which helps air movement while being very soft and durable.  BlackICE Hybrid Technology is another feature that gives you a cooling sensation that also works to keep you cooler at night.  The multiple layers of foam combined with the T3 Pocketed Coil Technology create comfort and conforming support.  Our pressure testing has confirmed that this mattress performs particularly well for back sleepers with its excellent back support for proper spine alignment.   The cost for one of these beds, in Queen size, is $3,099, which is the cheaper price of the CX Class models. This model is a great choice for a Beautyrest Black model, so long as you're willing to pay for premium quality.  I recommend this bed to anyone looking for a premium quality mattress, particularly if you're a back sleeper.
