Luxurious Comfort That’s Adaptable

by Jed Harrington

The Beautyrest Black L Class Plush is one of two mattresses in the Beautyrest Black collection this year that offers a really balanced level of comfort. Whether you sleep on your side, back, or stomach, this mattress is designed to give you a fantastic blend of comfort and support. Like other mattresses in the collection, the L Class Plush is crafted from some of the best comfort materials Beautyrest has to offer.

Plush, Conforming Comfort Paired With Firm Support

We gave the L Class Plush a true medium score of 5 on our Comfort Scale because it's soft enough to contour to your body’s curves and provide good pressure relief, without sacrificing firm underlying support.

The Best Support System From Beautyrest

The T3 Pocketed Coil system is among the best on the market today. It consists of a three piece design that braids high carbon steel into a system that's exceptionally conforming, durable, and supportive.

Some of the Coolest Rest Possible

BlackICE 4.0 combines four cooling components to provide you with cooler, more comfortable sleep.

Amazing Gel Memory Foam

The Gel Memory Foam layer closely contours to the unique shape of your body to help ease pressure points and contribute to comfort as well as durability.

A Great All-Around Luxury Design

If you're shopping for a luxury mattress with an excellent all-around feel, the Beautyrest Black L Class Plush may be the perfect choice for you.


Comfort This describes how a mattress feels. The Comfort Scale rating is based on how the cushioning materials conform to the body's shape. The higher the number the softer the mattress.

Quilt - Top of Mattress This is the outside cover on the top of the mattress. It covers and protects the comfort and support layers inside.

Comfort - Padding Layers This provides a cushioning layer between you and the support system in the bed. Different kinds of padding will provide different levels of comfort.

Correct Back Support System This is a general term used to describe how a mattress distributes and stabilizes body weight and maintains proper spinal alignment. Different materials provide different levels of support.
