Best For
- Side sleepers seeking the ultimate in pressure relief with luxury materials, as the thick super pillow top with Self-Response™ Latex, Micro Diamond™ Memory Foam, and multiple gel foam layers creates a plush, enveloping cradle at the shoulders and hips with perfect 10.0 pressure relief.
- Eco-conscious luxury shoppers who want premium performance with environmental responsibility, as the SEAQUAL Fabric Technology means each mattress diverts up to 100 plastic bottles from the ocean - sleeping well while doing good for the planet.
- Discerning sleepers seeking the pinnacle of Beautyrest engineering, as the Centennial collection represents Beautyrest's flagship with the exclusive T3 Triple Stranded Pocketed Coil Technology (2850 coils) plus 2K Micro Coils - a staggering 4850+ total coils delivering unmatched individualized support.
Considerations
- Stomach sleepers should approach with caution; the very deep sinkage (2.84 inches) and plush feel may allow excessive hip drop for stomach sleepers, particularly those over 150 lb. Stomach sleepers should consider firmer options.
- Responsiveness (8.7) reflects moderate bounce with slower surface response; the thick memory foam layers create deep contouring that can make repositioning take slightly more effort compared to firmer or all-latex options.
- At 16.5 inches and $3,139 (Queen), this is a flagship luxury mattress requiring extra-deep pocket sheets (20+ inches recommended) and representing a significant investment - though the exceptional construction and materials justify the premium for those who prioritize quality.
Feel & Firmness
At 5/10 on the firmness scale (accurate and comparable to other medium-firm mattresses), the Beautyrest Centennial 16.5" Super Pillow Top delivers a plush, luxurious sleep experience with substantial cushioning. With 2.84 inches (7.21 cm) of sinkage, you will experience a very deep plush hug with an enveloping, "wrapped" sensation at the shoulders and hips. The Sleep Climate™ Surface enhanced with cooling yarn provides a cool-to-the-touch sleep surface. The 0.5-inch SurfaceTouch™ Gel Memory Foam adds gel-infused surface contouring. The 1-inch Self-Response™ Latex provides responsive, breathable cushioning with immediate pushback. The 1-inch Micro Diamond™ Memory Foam and 1-inch Beautyrest® Gel Comfort Foam create deep pressure-relieving comfort. The support system features 1-inch Beautyrest Gel Memory Foam, 1-inch Beautyrest Firm Gel Support Foam, and 1-inch Beautyrest® Support Foam. The 2850 T3 Triple Stranded Pocketed Coils plus 2K Micro Coils beneath deliver the legendary Beautyrest individualized support.
The responsiveness score of 8.7 reflects moderate bounce with a slower surface response. While the pocketed coils and micro coils add spring, the thick memory foam layers create deep contouring. The Self-Response™ Latex adds immediate pushback that prevents the "stuck in the mattress" feeling. The combination provides a balanced feel that's plush yet supportive.
Cooling
This mattress earns a perfect 10.0 cooling score. The Sleep Climate™ Surface enhanced with cooling yarn provides a cool-to-the-touch sleep surface. The Self-Response™ Latex is naturally breathable. The gel-infused foams (SurfaceTouch™ Gel Memory Foam, Micro Diamond™ Memory Foam, Gel Comfort Foam, Gel Memory Foam, Firm Gel Support Foam) help draw heat away from the body. The 2850 T3 Triple Stranded Pocketed Coils plus 2K Micro Coils create massive open-air channels for continuous airflow. In temperature observations, the mattress showed a baseline of 22.0°C (71.6°F), a maximum of 30.5°C (86.9°F), and settled at just 25.3°C (77.5°F). This is exceptional cooling for a plush super pillow top mattress.
Motion Isolation
Scoring a perfect 10.0 for motion isolation, this flagship hybrid excels at minimizing sleep disturbances. The memory foam in the comfort layers (SurfaceTouch™ Gel, Micro Diamond™, and multiple gel foams) filters out partner movement on contact. The individually pocketed T3 Triple Stranded coils move independently, reducing motion from travelling across the bed. The 2K Micro Coils within the comfort system respond in localized sections rather than transmitting movement. The thick super pillow top construction adds extra damping for partner movement. This is ideal for couples where one partner moves frequently or has different sleep schedules.
Edge Support
With a perfect 10.0 edge support score, this mattress provides exceptional perimeter stability despite its plush feel. The reinforced perimeter and pocketed coil system help keep the edges stable for sitting and sleeping near the side. The T3 Triple Stranded Pocketed Coils with 13.75-gauge wire provide excellent edge integrity. Maximum edge sinkage was measured at 4.08 inches (10.36 cm), which is excellent for a 16.5-inch super pillow top. Couples who need to use the full sleep surface will appreciate the stable support from centre to edge.
Pressure Relief
The Beautyrest Centennial 16.5" Super Pillow Top earns a perfect 10.0 pressure relief score. The thick super pillow top with 0.5-inch SurfaceTouch™ Gel Memory Foam, 1-inch Self-Response™ Latex, 1-inch Micro Diamond™ Memory Foam, and 1-inch Beautyrest® Gel Comfort Foam creates a plush, contouring cradle at the shoulders and hips. The pocketed coils flex individually for targeted pressure-point relief while the 2K micro coils add extra cushioning and localized give. This design delivers exceptional pressure relief for side sleepers while the firm transition foams help prevent bottoming out.
Off-Gassing
As a flagship hybrid with CertiPUR-US® certified foams, this mattress may have a low initial odour upon delivery that typically dissipates within just 1 day based on reported experience - faster than most mattresses. The combination of breathable latex, certified foams, and massive dual coil airflow helps minimize and dissipate any new-mattress smell efficiently.
For best results, allow the mattress to air out in a well-ventilated room for several hours after delivery. Washing your sheets before first use can also help ensure a fresh sleeping environment.

Sleep Position & Body Weight Fit
The medium-firm feel (5/10) with very deep sinkage makes this mattress ideal for side sleepers who need their shoulders and hips to sink into a conforming surface for maximum pressure relief. The thick super pillow top creates an enveloping hug that cushions pressure points beautifully. Back sleepers will find excellent support as the T3 Triple Stranded coils maintain spinal alignment while the comfort layers add cushioning. Stomach sleepers should approach with caution - the very deep sinkage (2.84 inches) may allow excessive hip drop for stomach sleepers, particularly those over 150 lb. The firm transition foams and micro coils help prevent bottoming out for average-weight sleepers.

FAQs
Is the Beautyrest Centennial 16.5" Super Pillow Top good for hot sleepers?
Yes, this mattress is exceptional for hot sleepers, scoring a perfect 10.0 for cooling despite its plush pillow top design. The Sleep Climate™ Surface with cooling yarn, naturally breathable Self-Response™ Latex, multiple gel-infused foams, and massive dual coil airflow (2850 T3 coils + 2K micro coils) create outstanding temperature regulation. Temperature observations showed the mattress settling at just 25.3°C (77.5°F), which is excellent for a plush super pillow top.
Does the Beautyrest Centennial 16.5" Super Pillow Top feel like you sink in or stay on top?
You will sink into this mattress with a plush, enveloping hug. With 2.84 inches (7.21 cm) of sinkage and a medium-firm rating (5/10), this mattress creates a very deep "plush hug" with a wrapped sensation at the shoulders and hips. The thick super pillow top creates body-hugging contour while the T3 Triple Stranded coils provide underlying support to prevent bottoming out.
Is it a good choice for couples?
This mattress is excellent for couples, earning a 9.7 Couples/Intimacy score. It excels in motion isolation (10.0) with memory foam and the massive pocketed coil system (4850+ total coils) minimizing partner disturbance. Edge support (10.0) with reinforced perimeter allows both sleepers to use the full surface. Good bounce (9.4) from the dual coil system and latex provides responsive support.
What sleep positions is it best for?
The Beautyrest Centennial 16.5" Super Pillow Top is ideal for side sleepers who need maximum pressure relief at the shoulders and hips. Back sleepers will find excellent support from the T3 Triple Stranded coils. Stomach sleepers should approach with caution, as the very deep sinkage (2.84 inches) may allow excessive hip drop - firmer options would be more suitable for dedicated stomach sleepers.
How long does off-gassing usually last?
Based on owner feedback and the CertiPUR-US® certified foams used in this mattress, any initial odour is typically low and dissipates within just 1 day - faster than most mattresses. The breathable latex and massive dual coil airflow help circulate air and dissipate any odour efficiently. Allow the mattress to air out in a well-ventilated room after delivery.
What is SEAQUAL Fabric Technology and T3 Triple Stranded Pocketed Coil?
These are two flagship technologies that set the Centennial collection apart:
SEAQUAL Fabric Technology: The cover fabric is made using recycled ocean plastic. Each Beautyrest Centennial mattress diverts up to 100 plastic bottles from the ocean, turning marine waste into premium sleep comfort. This allows you to sleep well while contributing to ocean conservation.
T3 Triple Stranded Pocketed Coil®: Unlike standard pocketed coils that use single wire strands, T3 coils use three steel strands braided together. This creates:
• Greater durability and longevity
• Enhanced support and responsiveness
• Better motion separation
• Superior edge support
The Centennial combines 2850 T3 coils with 2K micro coils for a staggering 4850+ total coils - among the highest coil counts in any mattress available.
