The Beautyrest Black LX-Class Plush is one of three LX-Class models in Simmons' Beautyrest Black collection. Its back support and pressure-relieving capabilities make it ideal for back sleepers and it's one of the softer-feeling beds made by Simmons. If you're researching this model prior to purchasing please read our expert review here:

Comfort Scale Rating

Rated a 4 on our 10 point Comfort Scale (a 1 is hard, 10 is softest.) the Beautyrest Black LX Class Plush mattress is a medium-firm 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 LX Class mattresses with comfort more suited to your preferences.

Pressure Test Results

We have not had a chance to pressure test the new version of this mattress. These are the results of the previous model.

Once we test the new mattress, we will upload those results here. I expect them to be similar, if a bit better due to the additional gel memory foam, which is very pressure-relieving.

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 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.


The Black Hybrid LX Class Plush mattress is a medium-firm 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 three LX Class models, this one's the middle-of-the-road comfort, neither too firm nor too soft.  

Simmons' Zoned 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 cooling material which helps regulate the temperature in the mattress for a cooler night's sleep. This model's unique feature is a 1.5" layer of  AirCool Memory Foam which cradles your body excellently and gives you conforming support.

The Beautyrest Black Hybrid LX Class Plush mattress is priced pretty high but 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 like this mattress but think that a firmer comfort might be better, check out the LX-Class firm.

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.
