Beautyrest Black Series Three vs Series Four: Which to Buy

Beautyrest Black Series Four is the more premium of the two, and it is the one to buy if you want the brand’s most advanced support and cooling across the Beautyrest Black line. Series Three is the better choice when you want the classic quilted feel with responsive pressure relief at a lower listed price. Both are made for back and stomach sleepers, both carry a 100-night trial and a 10-year warranty, and both arrive with white glove delivery and free mattress removal. The gap between them comes down to micro coil count, the pillow top design, and price.

If neither fits your budget or your feel preference, the Saatva Classic is a strong alternative: it is an innerspring mattress with three comfort levels, a 365-night home trial, and free white glove delivery with old mattress removal.

Which Beautyrest Black should you buy, Series Three or Series Four?

You should buy Beautyrest Black Series Four if you want the most premium support and cooling available across the Beautyrest Black models, and you should buy Beautyrest Black Series Three if you want responsive pressure relief and the classic quilted feel at a lower listed price. Series Four adds 4K Micro Coils and an Apex Top design in all models; Series Three adds 2K Micro Coils in Pillow Top models only.

The two series share a great deal. Both use Triple-Stranded Pocketed Coil Technology as their support and motion separation system, both pair Self-Response Latex with SurfaceTouch Gel Memory Foam for pressure relief, and both use Sleep Climate Technology with Micro Diamond Memory Foam for temperature management. Both are described by the brand as made for back and stomach sleepers, and both are CertiPUR-US certified in their foams.

What separates them is the top of the mattress. Series Three offers feels that run from Extra Firm through Firm, Pillow Top Medium, Medium, Pillow Top Plush and Pillow Top Plush variants. Series Four offers Firm, Summit Pillow Top Medium, Pillow Top Medium and Pillow Top Plush. The Summit Pillow Top is the Series Four signature, and every Series Four model carries it.

How do Beautyrest Black Series Three and Series Four compare on paper?

Beautyrest Black Series Three lists from $3,449 for a Twin XL, while Beautyrest Black Series Four lists at $4,949. Both share a 100-night trial, a 10-year warranty, white glove delivery and free mattress removal, so the differences sit in the comfort layers and the micro coil count rather than in the policies.

The price figures above are the official listed prices on each product page. The Series Three page lists a range across sizes, from $3,449 for a Twin XL up to $5,199 for a Cal King, with Queen at $3,999. The Series Four page lists $4,949. Beautyrest runs sales frequently, so check today’s price before you order.

How do the two feel under you?

Beautyrest Black Series Three feels like a classic quilted innerspring with a responsive foam layer that contours as you move, and Beautyrest Black Series Four feels like the same classic quilted surface with a Summit Pillow Top that contours instantly in every model. Both series describe a firm option that supports without a deep sinking-in feeling, which suits back and stomach sleepers.

Series Three gives you the widest spread of feels. The page lists Extra Firm and Firm options alongside Pillow Top Medium, Medium and Pillow Top Plush variants, so a combination sleeper and a dedicated stomach sleeper can both land in the series. The brand’s own guidance is that firm options feel more supportive with less contouring, which makes them the natural pick for back and stomach sleepers.

Series Four narrows the spread but upgrades the top. Every model carries the Summit Pillow Top, described as foams that instantly contour to the body and respond to your movements for responsive pressure relief. If you want a pillow top feel in every configuration rather than in some of them, Series Four is the series that delivers it.

Neither page publishes a numeric firmness rating, so the feel words above are the brand’s own descriptions rather than a scale position. If you want a named third-party firmness scale to compare against, that figure is not part of what these two pages state.

Which one gives you more support?

Beautyrest Black Series Four gives you more support on paper, because it carries 4K Micro Coils in all models while Beautyrest Black Series Three carries 2K Micro Coils in Pillow Top models only. Both series build on Triple-Stranded Pocketed Coil Technology, which the brand describes as its most advanced motion separation.

The micro coil count is the clearest single difference between the two. Series Three adds 2K Micro Coils in Pillow Top models for increased individualized support, and the brand states that Series Four models have twice the amount of micro coils in the Series Three Pillow Top model. Series Four also adds an Apex Top design in all models, which the brand describes as an upgrade for overall pressure relief and edge support.

If you sleep on a non-pillow-top Series Three model, you are getting the Triple-Stranded Pocketed Coil system and the foam stack without the micro coil layer. If you want micro coils in every configuration, Series Four is the series where that is standard.

Do the two sleep differently hot or cold?

Beautyrest Black Series Three and Beautyrest Black Series Four use the same named temperature features: Sleep Climate Technology, Micro Diamond Memory Foam, and a cool-to-the-touch cover. Both series are described by the brand as designed to help you sleep cool, with the cover and the diamond-particle-infused memory foam working to transfer heat away from the body.

The two pages do not publish a measured cooling result, a temperature figure or a breathability test, so there is no basis here for calling one series the cooler of the two. If heat buildup is your main concern, the practical advice is simple: check the cover and foam descriptions on the model page you are actually buying, since both series list the same named features.

If cooling is the priority that decides your purchase, our best memory foam mattresses for 2026 covers models built around that question.

What do you get for the money with each series?

You get a lower listed price with Beautyrest Black Series Three, which starts at $3,449 for a Twin XL and reaches $5,199 for a Cal King, and you get the brand’s most premium configuration with Beautyrest Black Series Four at $4,949. Both include white glove delivery, free mattress removal, a 100-night in-home trial and a 10-year limited warranty, so the policies do not change with the series.

The value question is really about how much the micro coil upgrade matters to you. Series Three already carries the Triple-Stranded Pocketed Coil system, Self-Response Latex, SurfaceTouch Gel Memory Foam, Sleep Climate Technology and Micro Diamond Memory Foam. Series Four keeps all of that and adds 4K Micro Coils in every model plus the Summit Pillow Top in every model.

Buyers who want the classic quilted feel with responsive pressure relief and are not fussed about micro coils in every configuration will find Series Three the more sensible spend. Buyers who want the highest support and cooling tier the brand lists across the Beautyrest Black models should look at Series Four.

Both series are sold with financing options listed on the product pages, and both list CertiPUR-US certified foams, which the brand states are made without formaldehyde, flame retardants, prohibited phthalates and heavy metals, and meet low-VOC standards for indoor air quality.

What are the trial, delivery and warranty terms?

Beautyrest Black Series Three and Beautyrest Black Series Four both come with a 100-night in-home trial, a 10-year limited warranty, complimentary white glove delivery and free mattress removal. The trial lets you request a return and receive a full refund of your purchase if you are unhappy at any point during the trial.

White glove delivery on both series includes a call on the day of delivery confirming your delivery window. The brand describes the service as complimentary for mattresses sold on its site.

The 10-year warranty is a limited warranty on both series, and the brand states it stands by its Beautyrest mattresses with that term. Neither page publishes a longer warranty for Series Four, so the warranty is not a reason to step up between the two.

If a longer trial is what would make you comfortable, the Saatva Classic alternative above carries a 365-night home trial, which is longer than the 100-night trial both Beautyrest series list.

Who should buy Beautyrest Black Series Three?

You should buy Beautyrest Black Series Three if you want the classic quilted feel of a traditional mattress upgraded for responsive pressure relief, and you want to stay below the Series Four listed price of $4,949. Series Three starts at $3,449 for a Twin XL, offers the widest spread of feels from Extra Firm to Pillow Top Plush, and gives you 2K Micro Coils in Pillow Top models.

Series Three suits back and stomach sleepers, which is the position the brand lists for the series. It suits the buyer who wants Self-Response Latex for pressure relief that keeps responding as you shift, and SurfaceTouch Gel Memory Foam quilted directly into the surface for immediate pressure relief when you lie down.

It also suits the buyer who does not need micro coils in a non-pillow-top model. If you are choosing the Firm or Extra Firm feel, the micro coil layer is not part of that configuration anyway, so the Series Three upgrade over Series Two is what you are paying for rather than the micro coil count.

Series Three is the right series for a guest room or a first luxury purchase where the listed price matters as much as the construction. The 100-night trial gives you a window to confirm the feel suits you, and the white glove delivery means the old mattress leaves with the crew.

Who should buy Beautyrest Black Series Four?

You should buy Beautyrest Black Series Four if you want the most premium cooling, responsive pressure relief and individualized support the brand lists across the Beautyrest Black models, and you are comfortable with a $4,949 listed price. Series Four carries 4K Micro Coils in all models and a Summit Pillow Top design in all models.

Series Four suits back and stomach sleepers who want micro coils in every configuration rather than only in pillow top models. It suits the buyer who wants the Summit Pillow Top feel, described as foams that instantly contour to the body and respond to your movements.

It also suits the buyer who values edge support, since the brand lists an Apex Top design in all Series Four models as an upgrade for overall pressure relief and edge support. If you sit on the edge of the bed to get up in the morning, that design is the one the brand points to.

Series Four is the right series when the budget is not the deciding factor and you want the top tier the brand offers in this line. The policies are identical to Series Three, so nothing about the trial, warranty or delivery changes when you step up.

What is the Saatva Classic alternative?

The Saatva Classic is an innerspring mattress with a 3-inch Euro pillow top, a dual-coil design in triple-tempered recycled carbon steel, and three comfort levels: Plush Soft at 3/10, Luxury Firm at 5-7/10 and Firm at 8/10 on Saatva’s own scale, where 1 is softest and 10 is firmest. It carries a 365-night home trial and free white glove delivery with old mattress removal.

Saatva describes the Luxury Firm level as its most popular, designed to replicate the feel of luxury hotel beds and suited to all sleep positions and couples who cannot agree on firmness. The Plush Soft level is described as contouring and body-hugging, aimed at side sleepers and lighter-weight people. The Firm level is described as a floating-on-top feel for stomach and back sleepers and heavier body types.

The Saatva Classic also lists patented Lumbar Zone technology in the quilted surface, CertiPUR-US certified foams, and an endorsement from the American Chiropractic Association. Its foams and cover are described as breathable, with a dual-coil design that allows more airflow.

As an alternative to the two Beautyrest series, the Saatva Classic offers a longer trial at 365 nights against the 100 nights both Beautyrest series list, and it offers three named comfort levels with published firmness numbers rather than feel words alone. If you want to read more before deciding, our Saatva Classic review goes into the full construction.

The World Sleep Almanac editorial score for this face-to-face is 7.6/10, an editorial rating based on the criteria below rather than a laboratory test. Criteria are scored out of 10 and averaged.

• Materials and construction: 8/10. Both series list Triple-Stranded Pocketed Coil Technology, Self-Response Latex, SurfaceTouch Gel Memory Foam, Sleep Climate Technology and Micro Diamond Memory Foam, with CertiPUR-US certified foams.
• Trial and returns: 7/10. Both series list a 100-night in-home trial with a full refund option, which is shorter than the 365-night home trial Saatva lists for the Saatva Classic.
• Warranty: 7/10. Both series list a 10-year limited warranty, a standard term for the category.
• Delivery: 9/10. Both series list complimentary white glove delivery and free mattress removal, with a delivery window call on the day.
• Price at equal size: 7/10. Series Three lists $3,449 for a Twin XL against $4,949 for Series Four, so the step up carries a real premium for the micro coil and Summit Pillow Top upgrades.

Frequently asked questions

Is Beautyrest Black Series Four worth the extra cost over Series Three?

Beautyrest Black Series Four is worth the step up if you want 4K Micro Coils and a Summit Pillow Top in every model, which Series Three offers only as 2K Micro Coils in Pillow Top models. The listed price difference is $4,949 for Series Four against $3,449 for a Twin XL in Series Three. If you are choosing a Firm or Extra Firm feel, the micro coil layer is not part of that configuration, so Series Three is the more sensible spend.

Do both series come with the same trial and warranty?

Yes. Beautyrest Black Series Three and Beautyrest Black Series Four both list a 100-night in-home trial and a 10-year limited warranty, along with complimentary white glove delivery and free mattress removal. The policies are identical across the two series, so they should not influence which one you choose.

Which series is better for stomach sleepers?

Both Beautyrest Black Series Three and Beautyrest Black Series Four are listed as made for back and stomach sleepers. Series Three offers Extra Firm and Firm feels, while Series Four offers a Firm feel alongside its Summit Pillow Top options. The brand’s own guidance is that firm options feel more supportive with less of a contouring, sinking-in feeling, which is what stomach sleepers generally look for.

Does either series publish a numeric firmness rating?

No. Neither the Beautyrest Black Series Three page nor the Beautyrest Black Series Four page publishes a numeric firmness score. Both describe their feels in words such as Extra Firm, Firm, Medium and Plush, so you are comparing the brand’s own descriptions rather than a shared scale when you weigh the two series against each other.

What does white glove delivery include on these mattresses?

White glove delivery on Beautyrest Black Series Three and Beautyrest Black Series Four includes complimentary delivery with a call on the day confirming your delivery window, plus free mattress removal. Both series list the service as complimentary for mattresses sold on the Beautyrest site.
