Design and Build Quality

The Sweetnight CoolNest uses a traditional tight-top memory foam construction featuring multiple foam layers, PCM high-resilience foam, gel-infused memory foam, and a breathable polyester cover. The mattress is engineered around temperature regulation and ergonomic support. At approximately 54 pounds, it is relatively lightweight and easier to handle during setup.

The Novilla Bliss features a more premium Euro-top design that gives the mattress a plush and luxurious appearance. It uses a triple-layer foam system with NanoGEL memory foam and a cool-touch nylon cover containing 30% plant-infused fibers. The mattress feels more substantial, weighing nearly 80 pounds, which reflects its denser support structure.

While both mattresses are well-built, the Novilla Bliss feels more premium due to its Euro-top construction and reinforced edge support.

Cooling Performance

Cooling is one of the strongest selling points of both mattresses.

The Sweetnight CoolNest employs its proprietary CoolNest System, combining PCM (Phase Change Material) foam with gel-infused memory foam. PCM actively absorbs and releases heat to help maintain a stable sleeping temperature. The 3D-woven cover improves breathability by up to 35%, while the hollow-structured foam promotes three times greater airflow.

The Novilla Bliss takes a different approach with its 2X Cooling Technology. The cool-touch nylon cover feels noticeably cooler when first touched and works alongside NanoGEL memory foam to improve airflow and reduce heat retention. The plant-infused fibers further enhance temperature regulation.

For hot sleepers, both mattresses perform exceptionally well. However, the Sweetnight’s combination of PCM foam and advanced airflow design gives it a slight advantage in long-term temperature control throughout the night.

Comfort and Pressure Relief

The Sweetnight CoolNest uses a 5-zone ergonomic support system specifically designed to distribute body weight across different pressure points. This targeted support can be especially beneficial for side sleepers and people who experience shoulder or hip discomfort.

The Novilla Bliss uses a triple-layer foam design that adapts closely to body contours while maintaining spinal alignment. The mattress provides excellent pressure relief across the entire body and prevents excessive sinking.

While both mattresses excel in comfort, the Sweetnight’s dedicated 5-zone design offers more specialized pressure relief.

Support and Spinal Alignment

Proper spinal alignment is essential for reducing back pain and improving sleep quality.

The Sweetnight CoolNest provides balanced support through its zoned foam construction. Different areas of the mattress are designed to support various parts of the body independently.

The Novilla Bliss focuses on full-body support through its triple-layer system. The combination of cushioning foam and high-density support foam helps maintain neutral spinal alignment regardless of sleeping position. It also performs better for heavier individuals due to its stronger support core.

For overall support and versatility across sleeping positions, the Novilla Bliss holds a slight edge.

Motion Isolation

Couples often prioritize motion isolation to avoid sleep disturbances.

The Sweetnight CoolNest uses multiple memory foam layers that effectively absorb movement before it transfers across the mattress. Whether a partner changes positions or gets out of bed, movement remains largely isolated.

The Novilla Bliss also performs exceptionally well due to its thick memory foam layers and high-density support base. The mattress minimizes vibrations and movement transfer very effectively.

In real-world use, both mattresses offer excellent motion isolation and are suitable for couples.

Edge Support

Edge support impacts how much usable sleeping area a mattress provides.

The Sweetnight CoolNest delivers standard foam mattress edge support. Sitting or sleeping near the edge may result in some compression.

The Novilla Bliss specifically incorporates reinforced edge construction designed to improve perimeter stability. This allows sleepers to use the full mattress surface comfortably and makes getting in and out of bed easier.

This is a clear advantage for the Novilla.

The Novilla Bliss includes CertiPUR-US certification, OEKO-TEX certification, and ISPA certification. These certifications verify material safety, low emissions, and compliance with sleep industry standards.

The Sweetnight CoolNest includes a 10-year warranty but does not advertise a sleep trial period.
