Are you thinking about getting this top-of-the-line mattress from Beautyrest Black? The K-Class Ultra Plush Pillowtop is definitely a big-ticket item that needs to be researched, so we compiled our reviews and information on this bed so you can be more informed in your decision making:
Comfort Scale Rating
The K-Class Ultra Plush Pillowtop mattress has a soft, luxurious feel; we rate it a 7 on our 10 point Comfort Scale (a 1 is hard, 10 is softest.) This mattress will appeal to you only if you like a pretty soft bed. If you like anything firmer than that, you need to consider another mattress.
Pros & Cons
The Main Beautyrest Black K-Class Ultra Plush Pillowtop Features in Detail
1. Antimicrobial Mattress Protection
Keeps mattress fresh and clean from odor causing bacteria.
2. BlackICE 4.0 with Plant-Based Cooling Technology
Cooling materials just beneath the surface enhance heat dissipation that help provide up to 18% more cooling power to keep you comfortable while you sleep.
3. AirFeel Foam
A soft, quality foam located at the surface, with an open cell structure that helps provide airflow, performance and durability for the life of the mattress.
4. SurfaceTouch Gel Memory Foam
SurfaceTouch Gel Memory Foam is sewn into the quilt to work directly under the sleep surface to quickly unlock advanced pressure point relief from the moment you lie down.
5. AirCool Memory Foam
This proprietary memory foam conforms to your body, provides pressure point relief, and freedom of movement.
6. Alpaca, Cashmere and Silk Comfort Layer
This layer is 100% natural and will help wick away moisture and enhance the cooling features within the mattress.
7. Self Response Latex
Arguably the best comfort foam in mattresses, latex provides superior pressure relief for less tossing and turning while pushing back against the body for a more supportive feel. Anti-microbial and anti-dustmite properties contribute to a healthier sleep environment.
8. 2K Nano Coil
2000 micro coils provide enhanced conformability and pressure relief with individualized back support for each unique person.
9. T3 Pocketed Coil Technology
Exclusive to Beautyrest Black, this coil works to provide individualized back support, ease of movement, and pressure point relief throughout the night.
10. Energy Foam
This durable foam utilized below the coil unit helps create a supportive, durable foundation for the no-flip mattress design.
Compared to the old model, the new K-Class Plush Pillowtop mattress has SurfaceTouch Gel Memory Foam as well as Alpaca, Cashmere, and Silk Fibers in the comfort layers.
The K-Class Ultra Plush Pillowtop mattress has a 10-year warranty against factory defects.
Beautyrest Black K-Class FAQs
What is new to the Beautyrest Black K-Class Ultra Plush Pillowtop mattress?
The new models use SurfaceTouch Gel Memory Foam as well as Alpaca, Cashmere, and Silk Fibers in the comfort layers.
Do I need to flip my Beautyrest Black K-Class mattress?
No, Beautyrest Black 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.
The Black K-Class Ultra Plush Pillowtop mattress is a premium, soft-feeling mattress. This mattress is really only intended for you if you happen to prefer a softer mattress, and like to sink into the top of the bed. We carry another option if you like a firm mattress.
This model is the top of the line for Beautyrest Black, which is the overall top-of-the-line brand for Simmons Beautyrest mattresses. It's loaded with features including its best-pocketed coil design, its best cooling materials (BlackICE with Plant-Based Cooling Technology), and a layer of nano coils. It also has generous layers of memory foams and gel memory foams that bring the total height to 16".
This is a very tall mattress, so make sure you are ready for that. You should consider getting a low profile (short) foundation (4.5") rather than a regular size (9") to keep the overall height manageable.
It is expensive so it's really aimed only at people with that kind of money to spend on a mattress. If you don't want to spend so much, consider their other lower-priced models. For those looking to find the softest, most premium mattress, this is the one for you.
