Beautyrest Black C-Class Medium Pillowtop Mattress Review

Updated November 15, 2023

The Beautyrest Black C-Class Medium Pillowtop is a great, all-around luxury mattress. It's the sister model to the softer "Plush" Pillowtop model. We've outlined the features in our review below.  

Comfort Scale Rating

The C-Class Medium Pillowtop mattress has a firmer comfort feel; we rate it a 3 on our 10 point Comfort Scale (a 1 is hard, 10 is softest.) This mattress is sturdy but with some nice cushioning, due to the pillow top.

The Main Beautyrest Black C-Class Medium 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. SurfaceTouch Gel Memoy 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.

4. Firm Comfort Foam

High quality comfort foams in different levels of plushness used in various constructions to create comfort preferences.

5. GelTouch Foam

A soft gel foam that helps provide comfort, support, airflow and breathability.

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. 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.

9. Energy Foam

This durable foam utilized below the coil unit helps create a supportive, durable foundation for the no-flip mattress design.

New Features

The new C-Class Medium Pillow has a couple of differences from the previous model. There is now SurfaceTouch Gel Memory Foam as well as Alpaca, Cashmere, and Silk Fibers in the comfort layers.

Beautyrest Black C-Class FAQs

  1. Can I finance my Beautyrest Black C-Class mattress?

    Yes! You can finance a Beautyrest Black C-Class mattress on US-Mattress with Synchrony HOME, Affirm, or Paypal.

  2. How does the 120-night trial work?

    With the 120-night trial, try the mattress for at least 30 days, and up to 120 nights. If you're not satisfied, you can replace it. All you'll have to pay is a $139 processing fee, shipping and delivery are covered!

  3. What is the cooling system in this Beautyrest Black C-Class mattress?

    This mattress uses the BlackICE 4.0 with plant-basic cooling technology which lies just beneath the surface to enhance heat dissipation.


The Black C-Class Medium Pillowtop is very similar to the Plush Pillowtop model with the same prices and features. The only difference is this model has a 2" GelTouch Foam instead of 3" of Beautyrest Gel Memory Foam. This subtle difference gives the Medium model a firmer feel, not as soft as the other bed. It's a great bed if you're a back sleeper, giving you lots of support with just enough pressure relief.

It has the same key features as all Beautyrest Black beds: BlackICE cooling material and the Zoned T3 Pocketed Coils. It also has GelTouch Foam which is an advanced cooling and conforming foam. It is an advanced, premium foam in C-Class and K-Class models.

It's not a cheap bed and it's not in the range that most people can afford. However, it does offer good value for the price if you are shopping in this price range. The premium cooling materials, the comforting and conforming foams, and the advanced pocketed coil design are all worthy features.
