If you're researching this model prior to purchasing please read our expert review here:

Comfort Scale Rating

At a 6 on our 10 point Comfort Scale (a 1 is hard, 10 is softest.) the Beautyrest Black X Class Plush mattress is a medium-plush comfort.  This level of comfort will appeal to most people as it's neither too firm nor too soft.  However, if you really like a very firm or a very soft feeling mattress then you could look into one of the other X Class mattresses with comfort more suited to your preferences.

Pressure Test Results

The X-Class Plush mattress was 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 mattress performed decently well picking up four out of six 'recommended' scores with only one 'not recommended' score. The pressure relief and back support you get from the bed seems to work best if you're a back sleeper, though it does do a pretty good job for most side sleepers.  The red areas you see in the shoulder and hip region of the larger-sized body on the side sleeper indicate a significant increase in pressure, so much that this bed would likely cause discomfort for that person.  Yellow colorations in the images show where there's a build-up of pressure, more than what is considered normal.  The green and light blue areas are the best ones to see because they represent good pressure relief and the proper amount of support needed for quality sleep.

You should always consider how good a bed's back support is when shopping for a new mattress because a properly supported back will align your spine and distribute your weight on the bed for maximum comfort.  Improper back support tweaks your back out of alignment and spinal alignment is crucial to getting quality sleep.  Your body needs to have pressure relief so that you don't get that numb sensation in your limbs that lead to tossing and turning for a fitful night's sleep.  This bed performed really well for back sleepers, but only ok for side sleepers.

Conclusion

The Black Hybrid X Class Plush mattress is a medium-plush bed by Simmons.  It's a great comfort type for most people and is a good compromise if you and your sleep partner prefer different comfort levels in your mattress.  Of the four X Class models, this one's the middle-of-the-road comfort, neither too firm nor too soft.  It performed exceptionally well during pressure testing for back sleepers, earning a 'recommended' score for all body sizes.  It also picked up a 'recommended' score for petite people who sleep on their sides as well.  

Simmons' T3 Pocketed Coil System, which is exclusive to the Beautyrest Black models, is an amazing innovation in sleep technology as it supports you with greater resiliency than regular coils.  All of the Beautyrest Black models also have the BlackICE 4.0 cooling material which helps regulate the temperature in the mattress for a cooler night's sleep.  This model's unique feature is two 1.5" layers of  AirCool Memory Foam which cradle your body excellently and give you conforming support.

The Beautyrest Black Hybrid X Class Plush mattress is priced at $2,799 for a Queen size, and that's $600 cheaper than the most expensive of the X Class models.  You get phenomenal value for the cost as this bed is packed with premium materials and features that are difficult, if not impossible, to find in a comparable mattress.  If you think that a different comfort type might be a better option there are three other X Class models ranging from firm to ultra-plush.  This comfort is one of the most popular because of its plush feel and supportive structure for proper spinal alignment.  If you don't mind paying the price for a premium quality mattress and you like sleeping on a plush bed, particularly if you're a back sleeper, then this mattress is one of the best bedding options available.
