Pressure Test Results

We have not been able to test the new version of this mattress yet, so we are displaying the results from the previous model. We will update the review once we have the new testing done. It will likely have similar results, if a bit improved with the addition of gel memory foam that's been added to the LX-Class Firm.

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.

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.

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 foams which is what makes these beds a hybrid.

Conclusion The Beautyrest Black Hybrid LX Class Firm mattress is the firmest feeling of the three LX 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 LX Class models. For anyone who thinks that a softer feeling mattress would be a better choice for them, there are two other LX Class models that are all softer than this one. This mattress uses Firm Support Foam combined with the Zoned T3 Pocketed Coil System to give you a firmer feeling bed. This LX Class model has AirCool Memory Foam, which is arguably one of the best comfort foams in current bedding technology. The LX-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. Buy Now
