7 Best Beautyrest King Mattresses of 2025

This plush pillow top powerhouse delivers an indulgent sleep experience that’s tailor-made for side sleepers craving both softness and structured support. With a 16.25-inch profile, it stands tall among luxury king mattresses, featuring 1000-density Pocketed Coil Technology that provides exceptional spinal alignment and motion separation so precise, you’ll barely feel your partner shifting across the bed. The upgraded Beautyrest ActiveResponse MAX Memory Foam and SurfaceTouch Gel Memory Foam work in tandem to offer deep pressure relief, especially at the hips and shoulders—critical zones for side sleepers—while the InfiniCool MAX Technology ensures you don’t sink into a heat trap.

In real-world testing, this Beautyrest model excels on adjustable bases and pairs beautifully with heavier body types (230+ lbs) who need cushioning without bottoming out. The high-density foams resist sagging over time, and the natural lux fibers in the cover add a breathable, silky feel that enhances airflow. However, its substantial weight and full-size shipping mean setup requires help—no solo unboxing here. While it performs admirably on edge support, the plush surface may feel too soft for strict back or stomach sleepers needing firmer resistance.

Compared to the firmer Beautyrest World Class Level Three (B0F9B8M62Y), this Level Four trades some support for luxurious contouring, making it ideal for those prioritizing pressure relief over taut firmness. It’s not the most eco-conscious pick like the Harmony Lux Anchor Island, but it dominates in temperature management and adaptive comfort. For side sleepers who want a hotel-suite-level sleep surface with superior cooling and responsive memory foam, this Beautyrest stands out—offering more premium materials and depth than lower-tier models, even if it comes at a steeper investment.

Step into next-level luxury with the Beautyrest Black Series One—a premium plush mattress that strikes a rare balance between indulgent softness and engineered support. Its Triple-Stranded Pocketed Coil Technology is the star here, delivering unmatched motion isolation and personalized responsiveness that adapts to every shift in sleep position. The Soft GelTouch Foam and contouring memory foam layer create a cloud-like yet supportive cradle, perfect for those who want to sink in just enough without losing support. This is a true hybrid luxury experience, built for sleepers who demand both breathability and body-conforming comfort.

During extended use, the surface-cooling technology and vertical fibers effectively wick heat, keeping sleepers cool even during warmer nights—something many plush models struggle with. At 14 inches, it’s slimmer than pillow tops, making it a strong match for standard frames and sheets, and the CertiPUR-US certified foams ensure low off-gassing. However, the plush feel, while dreamy for side sleepers, may lack the lumbar reinforcement heavier back sleepers need. It also ships full-size, so delivery logistics require planning.

When stacked against the Beautyrest World Class Level Four, the Black Series One feels more refined and performance-driven, trading extra height for smarter thermal regulation and coil sophistication. It’s less about plush depth and more about precision engineering—making it the best overall pick for couples or hot sleepers who want luxury without overheating. While it doesn’t use recycled materials like the Harmony Lux, it delivers better airflow and advanced coil tech, justifying its higher price with long-term comfort and durability.

The Beautyrest Harmony Lux Anchor Island isn’t just a mattress—it’s a statement in sustainable innovation, blending eco-conscious design with serious sleep performance. Built with 1255 Series Pocketed Coils—40% more than standard Harmony models—it delivers remarkable support across all sleep positions, especially for combo sleepers who roll frequently. The Infinicool Lux technology uses plant-based cooling and dual cooling fibers to maintain a balanced sleep climate, while the Premium ActiveResponse memory foam ensures targeted pressure relief without excessive sink. But what truly sets it apart is its lush cover made from up to 116 recycled plastic bottles, proving luxury and sustainability can coexist.

In practice, this mattress shines for hot sleepers and environmentally aware buyers who don’t want to sacrifice comfort. The medium pillow top offers a balanced feel—soft enough for shoulder relief, firm enough for spinal alignment—and the enhanced edge support makes it ideal for sharing or sitting on the edge of the bed. However, the full-size shipping and bulky weight mean setup isn’t a one-person job. While cooling is strong, it doesn’t match the InfiniCool MAX intensity of the World Class models, and the eco-focus means fewer high-density foams than premium Black Series options.

Compared to the Days End line, the Anchor Island offers superior coil density and eco-credentials, making it the best eco-friendly king mattress in the Beautyrest lineup. It’s not as plush as the World Class Level Four, but it provides more balanced support and environmental impact than budget or basic models. For eco-minded couples or side-to-back sleepers who want green materials without compromising on cooling or support, this model delivers exceptional value through sustainability and performance—a rare combo in the luxury mattress space.

The Beautyrest Days End Medium Firm is a sleep-for-all-seasons champion, engineered for every sleep position and body type seeking a balanced, durable foundation. With its 875-density Pocketed Coil Technology, it delivers consistent support and solid motion separation, making it a top contender for couples with different sleep habits. The SurfaceTouch Gel Memory Foam is quilted directly into the cover, offering instant pressure relief at pressure points, while the InfiniCool Technology keeps the surface breathable—ideal for those who tend to sleep warm. At 14.75 inches, it has a generous pillow top without feeling overstuffed, striking a sweet spot between cushion and stability.

Real-world testing shows this model performs exceptionally well on adjustable bases, thanks to its flexible coil system and durable foam layers. The medium firm feel supports spine alignment for back and stomach sleepers while still offering enough give for side sleepers under 230 lbs. However, heavier individuals may find the foam layers compress slightly over time, and while cooling is effective, it’s not as aggressive as the MAX or Lux-tier systems. Like other full-size Beautyrests, delivery requires assistance, and the lack of compressed shipping may deter urban dwellers with tight staircases.

Against the Beautyrest World Class Level Three, this Days End model offers similar support at a much lower price, making it the best for all sleepers on a budget. It doesn’t have the high-density foams of premium lines, but it nails the essentials—cooling, motion isolation, and balanced comfort. For couples, families, or anyone wanting a reliable, no-frills king mattress that works for every body type, this Beautyrest delivers remarkable performance and versatility, outpacing many competitors in its class with adjustable base compatibility and long-term durability.

If unshakable support is your sleep non-negotiable, the Beautyrest World Class Level Three is a back and stomach sleeper’s dream, delivering a medium firm foundation that refuses to sag. Built with the same 1000-density Pocketed Coil Technology as its plush sibling, it offers superior motion separation and spinal alignment, making it ideal for restless partners or those with back pain. The World Class Relief High Density Foam and SurfaceTouch Gel Memory Foam provide targeted pressure relief without softening the overall feel—perfect for maintaining posture throughout the night. The InfiniCool MAX Technology adds a cool-to-the-touch surface that actively pulls heat away, enhancing comfort for warm sleepers.

In daily use, this mattress proves its mettle for combination and heavier sleepers (200+ lbs) who need resilience and structure. The 14.5-inch profile fits most bed frames and sheet sets, and the dense foam layers resist indentation better than lower-tier models. However, side sleepers may find it too firm, especially if they need deep hip cushioning. And like all non-compressed Beautyrests, delivery is a logistical challenge—this isn’t a mattress you’ll carry up stairs alone.

Compared to the Days End Medium Firm, the Level Three uses higher-density foams and a more advanced coil system, justifying its higher cost with longer lifespan and better temperature control. While it lacks the plushness of the Level Four, it’s the best for support in the World Class line. For those prioritizing back health, durability, and cooling, this Beautyrest offers premium engineering and targeted relief, making it a smarter long-term investment than entry-level models—even if it sacrifices some soft comfort.

Tailor-made for side sleepers who crave a soft embrace without sacrificing support, the Beautyrest Days End Plush Pillow Top delivers luxurious contouring at an accessible price. The plush pillow top layer molds gently to the shoulders and hips, reducing joint pressure, while the 875-density Pocketed Coils prevent excessive sink and maintain motion separation—a rare win in budget-friendly plush models. The SurfaceTouch Gel Memory Foam is quilted into the cover for instant cooling and pressure relief, and the InfiniCool Technology helps wick away heat, though not as aggressively as higher-end InfiniCool MAX systems. At 14.75 inches, it feels generous and inviting, perfect for those upgrading from an old, flat mattress.

In practice, this mattress shines for lighter side sleepers (under 230 lbs) who want cushioning without getting stuck. The adjustable base compatibility is a bonus for readers or couples with different preferences, and the CertiPUR-US foams ensure low odor and safety. However, heavier individuals may notice less lumbar support, and the full-size shipping means you’ll need help moving it. While it cools well, it can’t match the thermal performance of the Black Series or World Class lines.

Against the Beautyrest World Class Level Four, this Days End model offers similar plush comfort at nearly half the price, making it the best value for side sleepers. It doesn’t have the high-density foams or 1000-coil system, but it delivers core comfort and pressure relief where it matters most. For side sleepers seeking a soft, supportive, and affordable king mattress that won’t overheat, this Beautyrest strikes a perfect balance of plushness, cooling, and cost-effectiveness—a standout in the mid-tier plush category.

The Beautyrest Silver BRS900 is a budget-savvy sleeper’s secret weapon, proving you don’t need to splurge for reliable comfort and smart cooling. With 900 Series Pocketed Coils, it offers solid motion isolation and zoned lumbar support, especially from the Gel Memory Foam layer that targets lower back pressure—ideal for side and combo sleepers on a budget. The DualCool Technology fights heat and odor at the surface, while the AirFeel Foam adds a breathable, open-cell structure that enhances airflow. At just 12.25 inches, it’s lower profile, making it a strong fit for older frames or minimalist aesthetics, and it’s one of the most affordable king mattresses in the Beautyrest lineup.

In real-world use, it performs well for lighter sleepers (under 200 lbs) who want a soft, responsive feel without deep sink. The cooling is effective for mild night sweats, though not intense enough for hot sleepers in humid climates. The foam layers are thinner, so long-term durability may lag behind premium models, and the full-size shipping remains a hurdle. Still, for a budget pick, it includes CertiPUR-US foams and a 10-year warranty, offering peace of mind.

Compared to the Days End Plush, the BRS900 sacrifices pillow top depth and advanced cooling but wins on price and lumbar-specific support. It’s not as plush or tall, but for budget-focused buyers who still want brand reliability and temperature control, it’s the best entry point into the Beautyrest family. If you’re a lightweight side sleeper needing basic pressure relief and cooling on a tight budget, this model delivers essential features without fluff, making it a smart, no-gimmick investment in better sleep.
