My Take On The King-Sized Simmons Beautyrest Black Hybrid X Class Medium 13.5-Inch Mattress

by Jed Harrington

Would you like to add a new, firm mattress to your home furniture collection? The King-Sized Simmons Beautyrest Black Hybrid X Class Medium 13.5-Inch Mattress is a top-notch choice for your home.

Firm Support

The King-Sized Simmons Beautyrest Black Hybrid X Class Medium 13.5-Inch Mattress boasts a number of impressive features, including a comfort rating of four. This mattress is perfect for side and back sleepers alike. However, I wouldn't recommend it for stomach sleepers, who typically prefer a much softer sleeping solution.

Unbeatable Comfort

The King-Sized Simmons Beautyrest Black Hybrid X Class Medium 13.5-Inch Mattress is well worth the asking price, with RightTemp Memory Foam, Beautyrest Gel Memory Foam, Firm Comfort Foam, and Energy Foam for support. RightTemp Memory Foam utilizes conductive and strong carbon fibers for temperature management, while Firm Comfort Foam provides a much-needed layer of additional support and Beautyrest Gel Memory Foam guarantees exceptional pressure relief to reduce tossing and turning throughout the night. Energy Foam is placed below the coil system to create a supportive and durable foundation. Together, these foams make for a long-lasting and versatile sleeping experience.

Superb Coil System

In addition to its many benefits, the King-Sized Simmons Beautyrest Black Hybrid X Class Medium 13.5-Inch Mattress includes T3 Pocketed Coil Technology. This technology works to provide individualized back support and aid with motion transfer, should you choose to share your mattress with a sleeping partner.

Encasement System

For another bonus, the King-Sized Simmons Beautyrest Black Hybrid X Class Medium 13.5-Inch Mattress has a BeautyEdge Foam Encasement System. This system makes for a more consistent sleeping experience, giving you the ability to utilize the entirety of your mattress without risk of roll-off.

Cold as Ice

Finally, the King-Sized Simmons Beautyrest Black Hybrid X Class Medium 13.5-Inch Mattress has BlackIce Hybrid Technology. This impressive technology creates a top-of-the-mattress cooling sensation that will make falling asleep easier than ever.

A Great Call

In conclusion, the King-Sized Simmons Beautyrest Black Hybrid X Class Medium 13.5-Inch Mattress is a great choice for side and back sleepers alike. For many nights of exceptional comfort, consider adding the King-Sized Simmons Beautyrest Black Hybrid X Class Medium 13.5-Inch Mattress to your guest room, bedroom, or living space today.

amazingly comfortable
This mattress is amazing. I've struggled to find a matress that was firm enough to support my back without any pain, and soft enough to not feel like you're sleeping on the floor.

It's the first matress I've had that checks both of those boxes. It's a nice looking matress. It's well made, it's comfortable, supportive, and I can lay on my back at night without it hurting.

You can't go wrong with this hybrid x class

I have needed a new mattress for quite sometime. I have had back issues for many years and this mattress has relieved so much of my back pain! It’s very comfortable and has amazing support! I’m so glad I took the leap and tried this mattress!

Premium mattress with top craftsmanship
I've been using this for a week now and this is a truly premium mattress. I was using a mattress in a box before this and it never gave the support or cooling feeling this does. This mattress uses coils along with memory foam to give you the best of both features. The coils give you support so you don't sink in like a pure memory foam mattress and the foam evens out the pressure. The mattress really does pull away your heat as you sleep, as long as you don't have more than a sheet or two between you and the mattress. You won't feel cold or uncomfortable but you won't feel like you are overheating like the foam mattresses feel. The mattress is labeled medium but it's closer to firm. I haven't had it long enough to break it in but be sure to test it if you like a softer mattress. You will sink in a bit because of the memory foam after a few minutes and it will distribute your weight much better than a coil only mattress, so it won't feel firm while you are sleeping, just for a minute while the foam adjusts to you. Overall I'm very comfortable sleeping on this. The black color should do a good job hiding any stains it might get and keep it looking new much longer than light colored mattresses. The feel of the materials and stitching is all top notch. If you want a truly premium mattress, you can't do much better than this.

Great bed if you enjoy firmness!
While I personally do not love how firm this bed is (I prefer softer), my fiancé absolutely loves the firmness of this mattress and how much support it offers! I do like that the “hybrid” feature, it does give the bed a bit extra give since it has the springs and the memory foam.

I really love the cool feature of the memory foam, it helps to prevent you from getting too warm like other memory foam mattresses tend to do.

Overall I think that the quality of this mattress is great, it’s just probably a better fit for people who prefer pretty firm mattresses.

Great quality
We got this mattress for our ten-year anniversary. Our previous mattress was very soft, that's why this mattress feels very firm for us yet. But I know that it's healthier to sleep on firm mattress than soft one. After all, my husband and I started to feel more energetic. I wake up at 6.30 every day now since we got this mattress, I fall asleep around 11pm. So now we got used to firmness of this mattress and very happy!

Exemplary Product
I will admit I was at first skeptical about the cooling potential of this mattress with the comfort it claimed. Oh Boy have I never been more excited to be wrong. This mattress contours to my body perfectly providing the support I need and my husband as well. One major issue we have always had was being too hot when trying to sleep. Even in the cooler months it always seemed with our older mattress that it would just eventually, get to hot. Not this black beauty. It keeps us nice and cool all night long! I'm so comfortable I've almost completely forgot my husband snores like a wood chipper.

I LOVE This Mattress!!!
I received the Beautyrest BRB Hybrid Class Medium Mattress a week ago and I Love it!! Not only have I slept like a baby for the past 6 nights but I cannot find one single complaint about it. The Black/Grey color is so much better than white, I am a side sleeper and this mattress delivers. I can honestly say I have not woken up with a stuff neck or sore back either. I am also at that age where night sweats are a regular and yes I am still getting them but not sweating anything like I was before the new mattress. The way it controls movement is a big plus because my dog loves moving arounnd and I dont even fell it anymore. This mattress is def a 5 Star I would give it even more. I know people have said your mattress really makes a difference and I never knew how true that was until this Beautyrest.

This Beautyrest hybrid X mattress is the best mattress I’ve ever owned!
First of all, the mattress looks amazing. It is sleek and sexy. The Black makes it looks so expensive.
The comfort of the mattress is like no mattress I have ever owned. It is perfection in a mattress. The right amount of firmness and softness all wrapped up in one. I honestly can’t remember when I’ve had a better nights sleep.
The cool effect of this mattress makes it the absolutely perfect mattress. Surrounded by a cloud comfort while also staying cool.
This mattress is pure perfection. So comfortable. This mattress is so very beautiful.
I would recommend this mattress to friends and family over and over again.
