The Beautyrest Black Series Four is the top tier of the Beautyrest Black family and the brand’s most luxurious option overall. The official product page lists a price of $4,949.00 and describes the model as delivering the most premium cooling, responsive pressure relief, and individualized support plus motion separation available across all Beautyrest Black models. It is built for sleepers who want a classic quilted surface combined with upgraded coil and foam technology, and it is positioned as the choice for people who want the ultimate in luxurious sleep. The Series Four sits above Series One, Series Two, and Series Three in the Beautyrest Black lineup, and each step up adds features. The Series Four adds 4K Micro Coils and an Apex Top design across all models.

- Free white-glove delivery and old-mattress removal

Before you commit, compare the exact configuration you want against alternatives in the same price bracket. The Series Four does not try to be a budget hybrid or a universal medium feel. It is a firm-leaning luxury pillow top with a quilted classic surface, and it is priced accordingly.
Who is the Beautyrest Black Series Four for?
The Series Four is made for back and stomach sleepers, according to the official product page. It suits buyers who want a traditional quilted surface, a pillow top feel, and the highest level of support and cooling that Beautyrest lists within the Black family. It also fits shoppers who value white glove delivery and free mattress removal, both of which the brand includes with this model. Buyers who should look elsewhere include anyone with a tight budget, since the listed price is $4,949.00, and anyone who prefers a very soft, body-hugging feel, since the brand positions the firm options as better for back and stomach sleepers. If you want a longer trial period or a longer warranty, note that Beautyrest lists a 100-night trial and a 10-year limited warranty for this model.
The Series Four features a classic, quilted surface and a Summit Pillow Top design.
What does the spec sheet actually say?
The specifications describe a multi-layer build centered on coil technology and gel foams. The brand lists the following components for the Series Four: Triple-Stranded Pocketed Coil Technology for individualized support and motion separation, 4K Nano Coils (also described as 4K Micro Coils) for premium individualized support, Self-Response Latex for responsive pressure relief, SurfaceTouch Gel Memory Foam quilted directly into the mattress surface for immediate pressure relief, Sleep Climate Technology and Micro Diamond Memory Foam to help transfer heat away from the body, a cool-to-the-touch cover, an Apex Top design in all models for upgraded pressure relief and edge support, and a Summit Pillow Top design with foams that contour and respond to movement. The brand states that all Series Four options have twice the amount of micro coils in the Series Three Pillow Top model, which is intended to increase conformability. The foams are CertiPUR-US certified, meaning they are made without formaldehyde, flame retardants, prohibited phthalates, and heavy metals, and meet low-VOC standards for indoor air quality.

How does the Series Four feel and support you?
The Series Four offers four feel options: Firm, Summit Pillow Top, Medium Pillow Top, and Plush Pillow Top. The brand positions firm options as more supportive with less of a contouring, sinking-in feeling, making them ideal for back and stomach sleepers. Each model uses a Summit Pillow Top design with foams that instantly contour and respond to movement for responsive pressure relief. Support comes from the Triple-Stranded Pocketed Coil system paired with 4K Micro Coils, which the brand describes as its most premium individualized support and its most advanced motion separation. The Apex Top design appears in all Series Four models, which the brand says delivers overall upgraded pressure relief and edge support. Pressure relief is handled by two components: Self-Response Latex for responsive relief and SurfaceTouch Gel Memory Foam quilted into the surface for immediate relief. The brand describes the latex as conforming to your body, while the gel memory foam works from the very top of the mattress. The result, as the brand frames it, is a surface that responds quickly when you shift position rather than one that slowly recovers.
For back sleepers, the combination of a firm-leaning support core with a quilted pillow top surface is the classic formula: enough give at the surface to cushion the lumbar region, with a coil system underneath that keeps the spine aligned. Stomach sleepers get the same benefit from the firmer feel options, which the brand explicitly recommends for that position. If edge support matters to you, confirm the specific feel option you plan to order, since padding depth can change how the edge feels in practice.

Will the Series Four sleep cool?
Beautyrest states that all Beautyrest Black models are designed to help you sleep cool, and the Series Four adds a cool-to-the-touch cover plus diamond-particle-infused memory foam. The brand says these two elements are designed to help transfer heat away from the body so the bed stays cool. Sleep Climate Technology is also listed as part of the temperature management system. Cooling performance depends on your room temperature, bedding, and body type, none of which the official page quantifies. If you sleep hot, check the current product page for any updated cooling details before ordering, and confirm the cover material on the exact feel option you choose.
How good is motion isolation and edge support?
The brand claims the Triple-Stranded Pocketed Coil Technology offers its most advanced motion separation for an undisturbed rest, and that the pocketed coil system helps isolate motion between sleepers. Edge support is attributed to the Apex Top design, which the brand says is included in all Series Four models for overall upgraded pressure relief and edge support. These are brand-stated claims rather than independent test results. If you share a bed and are sensitive to partner movement, or if you sit on the edge every morning, verify the current product page for any updated details and consider the feel option that matches your needs. The Series Four is one of the few tiers in the Beautyrest Black family where the Apex Top design appears across every model rather than a single configuration, which is the brand’s argument for consistent edge behavior across the range.
What do trial, delivery, and warranty actually cover?
The Series Four comes with a 100-night in-home trial. The brand states that if you are unhappy at any point during the trial, you can reach out to initiate a return and receive a full refund of your purchase. Delivery is handled through a complimentary white glove delivery experience, and the brand confirms free shipping and returns plus free mattress removal. On the day of delivery, you get a call confirming your delivery window. The warranty is a 10-year limited warranty. Financing options are listed on the product page. For comparison, the Saatva Classic carries a 365-night home trial and a lifetime warranty, which is a meaningful difference at this price level. Read the full warranty terms on the official page before you buy, since coverage conditions matter as much as the headline number.
How does the Series Four compare with other Beautyrest Black models?
The Beautyrest Black family runs from Series One through Series Four, and each step adds features. Series One starts the family with individualized support and motion separation plus a cool-to-the-touch cover. Series Two adds enhanced cooling, deeply contouring pressure relief, and an Apex Top Medium model. Series Three adds responsive pressure relief and 2K Micro Coils in the Medium model for increased individualized support. Series Four carries everything from Series Three and adds 4K Micro Coils plus an Apex Top design in all models, along with premium foam and support upgrades for the most luxurious levels of cooling, responsive pressure relief, and support. All Series Four options have twice the amount of micro coils found in the Series Three Pillow Top model, which the brand says helps increase conformability.

Who should buy the Series Four, and who should not?
The Beautyrest Black Series Four, listed at $4,949.00, is built for back and stomach sleepers who want a traditional quilted surface and the highest level of support and cooling Beautyrest lists in the Black family. It suits buyers who value white glove delivery and free mattress removal, both included with this model, and who are comfortable with a 100-night in-home trial and a 10-year limited warranty. It does not suit shoppers on a tight budget, and it does not suit sleepers who want a very soft, body-hugging feel, since the brand positions the firm options as better for back and stomach sleepers. Side sleepers who want deep contouring and shoppers who want a trial period longer than 100 nights should compare alternatives before ordering.
Buy the Series Four if you sleep on your back or stomach and want free white-glove delivery and free mattress removal. Skip it if the listed price puts pressure on your budget, if you want a softer feel than the firm-leaning options suggest, or if a longer trial and longer warranty would give you more confidence at this price level.
What is the Saatva Classic alternative?
The Saatva Classic comes with a 365-night home trial instead of 100 nights. The Saatva Classic also comes with free white-glove delivery and free old-mattress removal, matching the delivery experience the Series Four offers. Where the Series Four gives you four feel options within one model line, the Saatva Classic gives you three comfort levels (Plush Soft, Luxury Firm, Firm) and two heights (11.5 inches and 14.5 inches) in a single named mattress. The Saatva Classic is built with a dual-coil design of over 1,000 recycled carbon steel coils in full size and up, triple-tempered for durability, plus patented Lumbar Zone Technology for spinal alignment. It is CertiPUR-US certified and GREENGUARD Gold certified, and it is endorsed by the American Chiropractic Association. If a long trial and lifetime warranty are priorities for you, the Saatva Classic is worth a look alongside the Series Four.
Verdict: The Beautyrest Black Series Four is the right choice for back and stomach sleepers who want a classic quilted luxury pillow top with twice the micro coils of the Series Three Pillow Top model, and who are comfortable with a 100-night trial and a 10-year warranty. It is the wrong choice for tight budgets, for very soft feel seekers, and for anyone who wants a longer trial or warranty at this price.
World Sleep Almanac score: 7.8/10
The World Sleep Almanac editorial score is based on five criteria: price at equal size, trial and returns, warranty, materials and construction, and public customer reviews. The Beautyrest Black Series Four earns 7.8/10 overall, with the following breakdown:
- Price at equal size: 7/10. The listed price of $4,949.00 places it at the top of the Beautyrest Black family and in the luxury bracket, which limits its appeal for budget-conscious buyers.
- Trial and returns: 7.5/10. A 100-night in-home trial with full refund on return is solid, but shorter than the 365-night trials offered by some competitors at this price.
- Warranty: 7/10. A 10-year limited warranty is standard for the category but shorter than lifetime warranty options available elsewhere.
- Materials and construction: 9/10. Triple-Stranded Pocketed Coil Technology, 4K Micro Coils, Self-Response Latex, SurfaceTouch Gel Memory Foam, Micro Diamond Memory Foam, and CertiPUR-US certified foams represent a premium build.
- Public customer reviews: 8/10. The Series Four sits at the top of a well-established luxury line with strong brand recognition in the premium mattress market.
