The Sweetnight CoolNest 16 inch King Mattress is designed to offer a comfortable medium firmness with excellent support thanks to its 5-zone ergonomic design. This targets pressure points across your body to help keep your spine aligned and relieve back pain, which is beneficial for those needing extra support during sleep. The mattress uses a combination of gel-infused memory foam and high-resilience foam that work together to absorb motion, helping reduce disturbances caused by a partner moving at night, making it a good choice for couples.

One of the standout features is its cooling technology. The CoolNest System and breathable cover improve airflow and help regulate temperature, making it suitable for hot sleepers or those who tend to overheat during the night. The mattress cover also wicks away moisture to keep you dry and comfortable. Edge support is decent due to the stable foam layers, allowing use of the full surface without feeling like you might roll off.

In terms of durability, the mattress includes CertiPUR-US certified foams and a 10-year protection plan, indicating it’s made with quality materials designed to last. Although memory foam mattresses can sometimes feel warmer than innerspring options despite the cooling features, and the medium firmness may be too soft for those who prefer firmer beds, it requires about 72 hours to fully expand after unpacking. This mattress fits adults seeking medium firmness, pressure relief, and temperature control—especially couples or hot sleepers—combining comfort, support, and cooling in a well-rounded king size memory foam mattress.

The Sweetnight King 12-Inch Hybrid Mattress offers a blend of comfort and support, making it a suitable choice for those seeking a balanced sleeping experience. Its design includes individually pocketed coils and multiple foam layers, which help in providing both softness and firm support, reducing the risk of sagging or rolling off the bed. This feature is particularly beneficial for individuals who require a mattress that supports varied sleeping positions and bodily contours.

The mattress is equipped with special foam that aids in regulating moisture, odor, and temperature. This can be a great advantage for people who experience night sweats or live in humid climates as it helps maintain a dry and comfortable sleeping environment. Additionally, the breathable fabric quilted cover enhances the overall comfort and ensures a skin-friendly touch.

Motion isolation is another strong point due to the pocketed coil design. This means that movements, such as your partner turning in bed, are less likely to disturb your sleep. This feature is ideal for couples or light sleepers who are easily awakened by sudden movements.

However, at 101.6 pounds, the mattress is relatively heavy, which could pose challenges for setting up or moving it. Although it fits most king-sized frames, ensure your existing frame can handle its weight and dimensions. The Sweetnight King Mattress suits those who value support and motion isolation in their sleeping surface, with the added benefit of temperature regulation. However, the weight and potential firmness should be considered based on personal preferences and physical capabilities.

Buying Guide for the Best Sweetnight Mattress

Choosing the right mattress is crucial for a good night's sleep and overall health. When selecting a mattress, it's important to consider various factors that will affect your comfort and support. Understanding these key specifications will help you make an informed decision and find the best fit for your needs.
Mattress TypeThe type of mattress refers to the materials and construction used. Common types include memory foam, innerspring, hybrid, and latex. Memory foam mattresses are known for their contouring and pressure relief, making them ideal for side sleepers and those with joint pain. Innerspring mattresses offer good support and are often preferred by back and stomach sleepers. Hybrid mattresses combine the benefits of memory foam and innerspring, providing both comfort and support. Latex mattresses are durable and offer a bouncy feel, suitable for those who prefer a more responsive surface. Choose a type based on your sleeping position and comfort preferences.
Firmness LevelFirmness level indicates how soft or hard a mattress feels. It is usually rated on a scale from 1 to 10, with 1 being very soft and 10 being very firm. Soft mattresses (1-3) are great for side sleepers and those who need extra cushioning. Medium mattresses (4-6) offer a balance of support and comfort, suitable for most sleepers, including combination sleepers. Firm mattresses (7-10) provide more support and are ideal for back and stomach sleepers who need to keep their spine aligned. Consider your sleeping position and personal comfort preference when choosing the firmness level.
SupportSupport refers to how well a mattress maintains your body in a neutral position, keeping your spine aligned. Good support is essential for preventing back pain and ensuring restful sleep. Mattresses with high-quality support systems, such as pocketed coils or high-density foam, provide better support. If you experience back pain or have specific support needs, look for a mattress that offers targeted support zones or enhanced lumbar support.
Motion IsolationMotion isolation is the mattress's ability to absorb movement and prevent it from transferring across the bed. This is particularly important for couples, as it minimizes disturbances when one person moves or gets up. Memory foam and hybrid mattresses typically offer better motion isolation compared to innerspring mattresses. If you share your bed with a partner, prioritize a mattress with good motion isolation to ensure uninterrupted sleep.
Temperature RegulationTemperature regulation refers to how well a mattress can maintain a comfortable sleeping temperature. Some mattresses tend to retain heat, which can cause discomfort during the night. Look for mattresses with cooling features such as gel-infused foam, breathable covers, or advanced airflow designs. If you tend to sleep hot, prioritize a mattress with good temperature regulation to stay cool and comfortable.
Edge SupportEdge support is the strength of the mattress's perimeter and its ability to hold weight without sagging. Good edge support is important for those who sit or sleep near the edge of the bed, as it provides stability and maximizes the usable surface area. Innerspring and hybrid mattresses often have reinforced edges, while memory foam mattresses may vary in edge support quality. If you need a stable edge, look for a mattress with strong edge support.
DurabilityDurability refers to how long a mattress will maintain its comfort and support over time. High-quality materials and construction contribute to a mattress's durability. Latex and hybrid mattresses are generally more durable, while lower-density foam mattresses may wear out faster. Consider the expected lifespan of the mattress and choose one that will provide lasting comfort and support.
