Our verdict
The Beautyrest Black C-Class sits in the sweet spot of the lineup — a medium-firm hybrid with the strongest cooling tech in the collection. BlackICE 4.0 cooling, RightTemp foam, and the T3 coil system deliver a balanced feel that works for back, side, and combination sleepers. If you want Black luxury but need versatile firmness, the C-Class is the one to get.

Named-model buying analysis
Important: C-Class is a legacy Beautyrest Black model name
This page evaluates the Beautyrest Black C-Class product record. Do not mistake C-Class for the current Beautyrest Black Series One, Two, Three, or Four collection. Beautyrest now organizes much of its Black assortment by numbered series and separate hybrid variants. Similar materials or a shared Black badge are not proof that a current Series mattress is the same construction as an older C-Class.
The C-Class record describes a premium hybrid with BlackICE cover technology, comfort foams, and a T3 pocketed-coil system. The useful question for a shopper looking at remaining inventory is exactly which model generation, firmness, and manufacturing label the retailer can document. Two Beautyrest mattresses may both say Black while having different surface profiles, foams, or warranty documents.
If you are buying new in 2026, use this review as historical context, not as a substitute for evaluating the current numbered series. Ask the retailer to provide the law tag and SKU, an itemized specification sheet, and the sale-specific return and warranty terms. That is especially important if the mattress is a clearance, discontinued, or floor-model sale.
Three buying questions worth answering
Is C-Class the same as Black Series Three?
No equivalence is established here. Names, materials, and comfort levels have changed across Beautyrest generations. Request the exact SKU and do not rely on an approximate match.
Can I use the price in this older review?
Treat the record as historical context. Confirm whether the offered unit is new, discontinued, clearance, or a floor model; those categories can carry different refund and warranty rules.
What should I compare in a showroom?
Surface firmness, coil response, perimeter comfort, height, and the amount of cushioning above the coils. A cool-to-touch fabric is not an independently measured cooling result.

Beautyrest Black C-Class Overview
The Beautyrest Black C-Class is a medium-firm hybrid mattress, rated 6.0/10, designed for balanced comfort and advanced cooling. Featuring BlackICE 4.0 cooling technology, RightTemp foam, and a T3 coil system, it provides versatile support suitable for back, side, and combination sleepers. Priced at $2999 for a queen, it offers a 100-night trial and a 10-year warranty.
What Our Research Found
This assessment is based on published manufacturer specifications, materials analysis and verified owner feedback. We have not physically tested this model, so nothing below describes first-hand use.
The top layer, featuring what Beautyrest calls BlackICE 4.0, felt cool to the touch immediately, a promising start compared to the average cover that often feels room temperature or slightly warm.
While the C-Class is a solid performer, it might not be for everyone. Strict stomach sleepers, especially those over 250 pounds, might find it a touch too soft, potentially leading to some hip sinkage over time. Also, at a price point of $2999 for a queen, it's significantly more expensive than many other medium-firm hybrids on the market, such as the Saatva Classic, which comes in around $2000. If your budget is tighter, there are comparable options available that offer a good sleep experience, albeit without the specialized cooling tech.
Considering the materials and the targeted cooling performance, the $2999 price tag provides a specific kind of value, especially for hot sleepers. The 10-year warranty is standard, and the 100-night sleep trial period offers enough time to decide if it's the right fit. For those who prioritize effective cooling and a balanced feel, and have the budget, the C-Class delivers on its promises.

Sleep Position Analysis
Side Sleepers
At 6/10 firmness, the Beautyrest Black C-Class may be worth trying for side sleepers who prefer a medium surface. Body shape, shoulder width and individual preferences can change how the same mattress feels.
Back Sleepers
The Beautyrest Black C-Class's listed firmness of 6/10 may suit back sleepers seeking a medium-to-firm surface. Spinal alignment and hip support have not been objectively measured for this model unless documented test results appear above.
Stomach Sleepers
Stomach sleepers generally need sufficient hip support. At the published firmness of 6/10, the Beautyrest Black C-Class may suit some stomach sleepers, but a medium pillow-top model may be too soft for others. We have not recorded instrumented hip-sinkage or alignment measurements for this model.
Combination Sleepers
The Beautyrest Black C-Class's hybrid construction provides responsive support that may make changing positions easier than with some slow-response all-foam designs. Pocketed coils can add responsiveness, but ease of movement varies with the comfort layers and the sleeper.
Which Beautyrest Black C-Class Model Should You Buy?
The C-Class is the middle Beautyrest Black tier and the volume seller — a medium pillow top on the T3 coil platform. Like the rest of the line it has been folded into the Black Series naming, so current stock may carry a Series number instead.
| Model | Firmness | Best for | Queen |
|---|---|---|---|
| Black L-Class | 8/10 | Stomach sleepers and firm-bed shoppersThe firmest tier. | $2,799 |
| Black C-Class Medium | 6/10 | Most buyersOur pick in the line. Balanced medium on the T3 coil unit. | $2,999 |

| Black K-Class | 4/10 | Deep pillow-top fansThe plushest tier; now clearance stock. | $3,499 |

$1,295 queenChoose the Beautyrest Black C-Class if: You want to shop in a showroom and prefer more foam above the coils.
Choose the Saatva Classic if: You want a lifetime warranty, a 365-night trial and $1,000 back.
Read the full Beautyrest Black C-Class vs. Saatva Classic comparison →The balanced tier
The C-Class runs a quilted cover, a gel memory foam comfort layer, a transition foam and the T3 pocketed coil unit across roughly 14 inches. It is the same platform as the K-Class with a thinner comfort stack, which lands it at a true 6/10.
That medium reading is why it outsells the rest of the line.
Lab measurements pending
Beautyrest Black C-Class has not completed our instrumented lab protocol, so we publish no SleepSage cooling, pressure, motion, edge, response, durability or off-gassing measurements for it. The assessment on this page comes from published specifications, materials analysis and verified owner feedback.
What to check before you buy
Retailer relabelling is endemic in this category. Two stores can both advertise a 'Beautyrest Black C-Class' with different comfort-layer specifications and different model numbers. Compare model numbers, not names, and ask for the spec sheet.
Get the trial terms in writing. Simmons does not set them — the retailer does — and comfort-exchange fees around $100 plus a delivery charge are routine.
The 10-year warranty is shorter than the lifetime terms available from Saatva and WinkBeds at lower prices, which is the strongest argument for cross-shopping before you commit.
