Pressure Test Results
The X-Class Firm 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 pressure relief you can expect. (Learn how we test.)
This mattress tested very well, earning four out of six 'recommended' scores for its ability to relieve pressure on your joints and provide proper back support. Peak pressure point relief is what ensures that your limbs don't go numb. It means the mattress is doing a good job of dispersing your weight across the bed. Spinal alignment through proper back support is essential to a quality night's sleep as well because a back that is out of alignment causes pain, stiffness, and makes you very weary the following day. The X-Class Firm did a pretty good job of relieving pressure and providing proper back support for all body size/sleep position combinations.
The exception is heavier side sleepers. This was the only sleeper type that this bed earned a score of 'not recommended'. It's not very surprising, as firmer beds tend to cause more pressure the heavier the person is. This doesn't mean that you'll find the bed uncomfortable, just that it's not your ideal blend of support and comfort.
So that you can read these test results you'll need to know what each color shown represents. The red areas, as seen on the side sleeper with a larger-sized body, mean that there's a lot of pressure on that joint which will lead to tossing and turning for a very disturbed night's sleep. The yellow areas show where there's an increase in pressure, though not so much that the bed would very uncomfortable. The green areas show you where the pressure relief is good for that part of the body while light blue areas indicate appropriate back support. I hope this helps you in your decision-making process if you're tossing around the idea of purchasing this model.

Conclusion
The Beautyrest Black Hybrid X Class Firm mattress is the firmest feeling of the four X Class models offered by Simmons. If you're shopping for this firm feeling (not hard!) mattress then you need to be aware that you're getting the firmest of all X Class models. For anyone who thinks that a softer feeling mattress would be a better choice for them, there are three other X Class models that are all softer than this one. This bed did earn a 'recommended' score on 4 of the 6 sleep position/body size combinations during our pressure testing. In fact, this bed comes highly recommended for back sleepers of all sizes. It even earned a recommendation for side sleepers with petite bodies.
This mattress uses Firm Support Foam combined with the T3 Pocketed Coil System to give you a firmer feeling bed. This is the only X Class model that has Self Response Latex, which is arguably one of the best comfort foams in current bedding technology.
The X-Class Firm mattress is one of the more expensive Beautyrest Black models currently available. However, this bed is loaded with premium materials and is a very high-quality construction. I would recommend this bed to anyone who wants one of the best firm-feeling beds. It's certainly a great value for the number of premium materials you get. Be warned though, a firm feeling bed like this is not for everyone, particularly side sleepers.
