Introducing the SweetNight CoolNest® Hybrid Mattress

SweetNight will proudly introduce its newest creation, the SweetNight CoolNest® Hybrid Mattress. This formal introduction marks a significant improvement in modern sleep design, combining enhanced cooling performance with precision-engineered hybrid support.

Today's sleepers want more than just a comfortable bed. They want to be able to control the temperature, keep their spine in line, and make sure it lasts. The SweetNight CoolNest® Hybrid Mattress was made to meet those needs right away. By integrating CoolNest® System with Innovative Dynamic Coil™ Technology, this new release delivers a balanced medium-firm feel designed to support deeper, more restorative rest.

If you want a cooling hybrid mattress that tackles sleep issues without losing comfort, this launch is for you.

Advanced Cooling Technology for All-Night Temperature Control

Overheating is one of the most common causes of disrupted sleep. That's why the SweetNight CoolNest® Hybrid Mattress was designed with a true multi-layer cooling system, not just a surface treatment.

This cooling hybrid mattress dynamically regulates temperature from sleep to wake up, unlike memory foam beds that retain heat.

Cooling Ice Silk Cover with Enhanced Airflow

The top layer has a special Cooling Ice Silk Cover with more than 10,000 micropores per square centimeter. This design with vents lets 30% more air flow through, which helps get rid of body heat and moisture faster.

When compared to traditional cooling materials, the fabric offers up to 47% better cooling performance with a Qmax value of 0.25 J/(cm²·s). The difference is noticeable immediately. Instead of feeling stuffy, the surface feels refreshingly cool to the touch.

For hot sleepers, that instant cooling sensation can make falling asleep significantly easier.

Third-party tests show that the CoolNest® Hybrid Mattress cooling fabric delivers 721 mm/s air permeability, about 30% higher than regular fabrics (around 550 mm/s). The fabric also features a contact cooling coefficient of 0.25 J/(cm²·s), providing about 47% stronger cooling performance than standard cooling fabrics.

30% Gel-Infused Memory Foam for Pressure Relief

There is 30% gel-infused memory foam under the cover. This layer gently shapes to your body and pulls heat away, making you feel comfortable and keeping your body temperature stable. The SweetNight CoolNest® Hybrid Mattress makes it less likely that you will toss and turn by cushioning pressure points at the shoulders, hips, and lower back. If you move around less at night, you'll spend more time in deeper sleep cycles. You get the contouring feel of memory foam without the trapped-heat drawback many people dislike.

PCMflux® High-Resilience Foam for Dynamic Cooling

This cooling hybrid mattress goes even further with PCMflux® high-resilience foam infused with phase-change material (PCM). PCM works dynamically. When your body temperature rises, it absorbs excess heat. It releases stored warmth when it falls.

According to SweetNight tests, mattresses without PCM can reach 86°F while you're sleeping. Surfaces with PCM stay closer to 78°F, which keeps the climate more stable and comfortable. The hollow, large-pore foam structure also increases airflow up to three times, preventing heat buildup within the mattress core.

Third-party tests show that PCMflux™ High Resilience Foam reaches 1827.78 L/(dm²·min) in air permeability, compared to 582.53 L/(dm²·min) for regular foam—providing up to 3× greater breathability.

Hybrid Ventilated Structure

Cooling performance doesn't just happen at the top layers. The whole SweetNight CoolNest® Hybrid Mattress is made to let air flow through it. Air can move freely because of the open coil construction, breathable fabric, and ventilated foam channels. The result is a fresher, cooler sleep environment that lasts through the night, not just the first hour.

Advanced Structure with 360° Support

Dynamic Coil™ Technology for Adaptive Support

Cooling comfort only matters if your body is properly supported. At the heart of the SweetNight CoolNest® Hybrid Mattress are 600 individually pocketed coils designed for adaptive support. Each coil works on its own to support your weight and movement, giving you extra support where you need it most.

Performance highlights include:

• 20% greater deformation for improved contouring
• 25% stronger energy reserve for responsive rebound
• Less than 15% motion transfer
• Noise levels at or below 25 dB

Durability tested through 100,000 pressure cycles. For couples, this implies they will sleep better. The other person doesn't notice much movement when the first one does. The mattress' level of motion isolation makes it ideal for shared beds.

The above results are based on internal testing conducted by the SweetNight Laboratory.

Reinforced Edge Support for Stability

A 10 cm high-density foam perimeter strengthens the outer edges of the SweetNight CoolNest® Hybrid Mattress. This prevents sagging and increases usable sleep space. You can sit comfortably on the edge while getting ready in the morning, and you won't feel like you're rolling off when sleeping near the side. Strong edge support also improves long-term durability.

Zoned Support for Proper Spinal Alignment

The zoned construction and high-density support foam work together to maintain a healthy position for your spine. Whether you sleep on your back, side, or stomach, this cooling hybrid mattress helps maintain natural posture. Proper alignment reduces strain on the lower back and minimizes morning stiffness, making the mattress suitable for a wide range of sleepers.

DuoSense™ Pillow Top for Balanced Comfort

The SweetNight CoolNest® Hybrid Mattress has a DuoSense™ Pillow Top with extra padding in two layers. When you initially lie down, you will feel like you're being gently held. There is a medium-firm support system under that soft surface that keeps you from sinking too far in. This careful balance makes sure you stay comfortable without losing the strength of the structure. It's softness and support working together instead of competing.

Who Is the SweetNight CoolNest® Hybrid Mattress Designed For?

This new release was created to meet the needs of diverse sleepers.

Hot Sleepers: If you frequently wake up overheated or sweaty, this cooling hybrid mattress directly addresses temperature regulation with its layered cooling system.

Couples: With under 15% motion transfer and quiet coil performance, the SweetNight CoolNest® Hybrid mattress minimizes disturbances from partner movement.

Back, Side, and Stomach Sleepers: The balanced medium-firm feel makes it versatile. Side sleepers receive pressure relief at hips and shoulders. Back sleepers benefit from lumbar support. Stomach sleepers gain midsection stability. This adaptability makes it suitable for households with mixed sleep preferences.
