Beautyrest Black® Hybrid CX-Class 13.5" Medium Mattress in Kentucky
The Beautyrest Black® Hybrid CX-Class Medium is a luxury hybrid for shoppers who want contouring comfort on top with coil support underneath. In the Mattress Overstock showroom, compare this model in your normal sleep position and pay attention to shoulder pressure, lower-back support, edge feel, motion transfer, cooling feel, and whether the 13.5-inch profile works with your frame, foundation, or adjustable base.
What to compare on this Beautyrest Black® Hybrid
- Medium hybrid feel: The CX-Class Medium should feel more balanced than a plush pillow top and less rigid than an ultra-firm mattress. Try it on your side, back, and stomach before deciding whether the support feels right for your body.
- BlackICE™ cooling materials: Beautyrest builds this line with cooling-focused cover and comfort materials. Test the surface feel in person and ask how your sheets, protector, room temperature, and foundation can affect heat retention at home.
- T3 Pocketed Coil® support: The triple-stranded coil system is designed to add support and motion separation. Couples should test partner movement and edge sitting, not just the center of the mattress.
- Natural-fiber comfort layer: Cashmere, alpaca, and silk fibers add a breathable luxury layer near the top of the bed. Compare it against other Beautyrest Black models if surface feel and airflow are priorities.
- Self-Response™ latex and comfort foams: The latex and foam stack gives this mattress a more responsive feel than an all-foam bed. If you dislike feeling stuck in a mattress, spend extra time comparing this layer against memory-foam-heavy models.
Who should try the CX-Class Medium
- Shoppers who want a luxury hybrid with a balanced medium feel.
- Couples comparing motion transfer, edge support, and a mattress that is easier to move on than slow-response foam.
- Side and back sleepers who want pressure relief without losing the lifted support of a coil system.
- Hot sleepers who want to compare cooling materials in person instead of buying from a spec sheet alone.

Beautyrest builds the feel around pocketed coils first, then tunes it with foam above
Beautyrest hybrids and premium innerspring builds rely on independently wrapped coils to do the heavy support work. That keeps the surface more stable through the middle while preserving easier movement than an all-foam bed.
The comfort foams and cooling package on top change how deeply you settle in, how much pressure relief you get at the shoulders and hips, and how warm the surface feels through the night.
Compared with the Beautyrest Harmony Lux Hybrid Ocean View Island Medium, the Beautyrest Black Hybrid CX-Class 13.5" Medium is tuned a little differently than the Beautyrest Harmony Lux Hybrid Ocean View Island Medium. That is the practical difference you feel in the showroom: the medium hybrid surface changes how deeply you settle in, while the underlying coil core changes how easy it is to move and how steady the edge feels.
Shop all Beautyrest mattresses →Built for the way you actually sleep
Combination sleepers - The feel is balanced enough to work for shoppers who rotate between side and back sleeping instead of committing to one position.
Couples - This middle-of-the-line tuning is usually the easiest compromise when two sleepers do not want the same thing from the surface.
People who move a lot - The coil core adds rebound and stronger edge support, so it is easier to change positions than a slower all-foam build.
Hot sleepers - This version is the better cooling choice in the line because airflow can move through the coil section as well as the cover and comfort layers.

Frequently asked questions
How firm is the Beautyrest Black Hybrid CX-Class 13.5" Medium?
We rate it 5 out of 10 (10 = firmest). In practical terms, that puts it in the medium hybrid part of the lineup. The right fit depends on your sleeping position, body type, and whether you like to sleep more on top of the mattress or more in it.
How is the Beautyrest Black Hybrid CX-Class 13.5" Medium different from the Beautyrest Harmony Lux Hybrid Ocean View Island Medium?
The Beautyrest Black Hybrid CX-Class 13.5" Medium and the Beautyrest Harmony Lux Hybrid Ocean View Island Medium are close enough in the lineup that most shoppers should compare them side by side. The biggest difference is feel: the Beautyrest Black Hybrid CX-Class 13.5" Medium lands on the medium hybrid side of the lineup, while the Beautyrest Harmony Lux Hybrid Ocean View Island Medium feels more medium hybrid.

How fast can I get it delivered in Kentucky?
We deliver with our own team across Kentucky. Most orders arrive the next business day when the size is in stock. Pickup is available at our Lexington, Georgetown, Somerset, London, and Richmond locations.
What if I do not like it after a few nights?
You have 100 days to make sure the comfort is right. We usually recommend giving any new mattress at least 21 nights before making a comfort decision, because covers and foams need time to settle and your body needs time to adjust.
Can I try it before I buy?
Yes. We have these models represented across our Kentucky showrooms, so you can lie down on the feel before you buy. Walk in, take your time, and compare it against the nearby step-up and step-down models.
