More Details on Our Top Picks
Novilla King Size Gel Memory Foam Mattress, 12 Inch
The Novilla 12-inch gel memory foam mattress stands out for its combination of cooling features, support, and safety certifications. Compared to the Celestial Sleep 10 Inch Split King, it offers a thicker profile, which translates into more plushness but also adds weight and setup time. Its cooling gel foam enhances airflow, making it a solid choice for hot sleepers who prioritize temperature regulation. However, its 72-hour expansion period and heavier weight could be drawbacks for those who need quick setup or frequent repositioning. This model suits buyers seeking a well-rounded mattress with safety certifications and a medium plush feel, but less so for those who prefer a softer or ultra-light option.
Pros:- Cooling gel memory foam promotes airflow and reduces heat buildup
- Supports spinal alignment and relieves pressure points
- CertiPUR-US and OEKO-TEX certified for safety and health
- Easy to set up with vacuum packaging
Cons:- Requires 72 hours to fully expand and air out
- Heavy weight may be difficult to move
Best for: Sleepers looking for a supportive, temperature-regulating mattress with a focus on safety and a plush feel.
Not ideal for: Individuals who want an ultra-soft mattress or need a lightweight option for frequent movement.
- Size:King (U.S. Standard)
- Thickness:12 inches
- Material:Gel Memory Foam, High Density Foam

EGOHOME King 14 inch Memory Foam Mattress for Back Pain Relief Medium Firm
The EGOHOME 14-inch mattress emphasizes support for back pain relief, with its medium-firm feel and advanced cooling technology like graphene and copper gel infusion. Compared to the Novilla Bliss 14-Inch Gel Mattress, it offers a slightly thicker profile with a focus on orthopedic benefits, endorsed by the International Chiropractors Association. Its support and pressure relief make it suitable for sleepers with back issues or those seeking a firmer feel. However, its 96-pound weight and lack of a trial period may limit flexibility for some buyers. This pick makes sense for those prioritizing support, temperature regulation, and certification, but less so for casual sleepers or those needing a softer surface.
Pros:- Cooling fabric with graphene technology for temperature regulation
- Supports healthy sleep with pressure relief and orthopedic features
- Made with CertiPUR-US certified foam, safe and durable
- Easy delivery with mattress in a box
Cons:- No trial period; opened mattresses cannot be returned

Compared to the Celestial Sleep 12 Inch Split King, it provides a thicker profile and reinforced edge support, appealing to those who prioritize comfort and stability. Its cooling gel foam helps minimize heat buildup, making it suitable for hot sleepers. On the downside, its weight of over 92 pounds and the need for a 72-hour expansion period could be inconvenient.

Celestial Sleep 10 Inch Split King Mattress, Made in the USA, CertiPUR-US®, Oeko-Tex®, Fiberglass-Free™, Cooling Gel Memory Foam in a Box
The Celestial Sleep 10 Inch Split King prioritizes ease of setup and cooling, with a thinner profile and multiple layers designed for all sleep positions. Compared with the thicker Novilla options, it offers a lighter weight at 78 pounds, making it easier to handle but with potentially less plushness and support. Its multiple comfort layers support various sleeping styles, and being made in the USA with certified safe materials adds peace of mind. The main tradeoff lies in its shorter lifespan and limited durability data, which may concern long-term buyers. This mattress is ideal for those who want a straightforward, cooling, in-a-box solution with easy handling, but less suited for heavy or long-term use.
Pros:- Cooling gel-infused memory foam for temperature regulation
- Supports all sleep positions with multiple comfort layers
- Made in the USA with certified safe materials
- Easy to set up—unbox, unroll, and sleep
Cons:- Heavy at 78 pounds, may need help for setup
- Limited info on long-term durability
Best for: Hot sleepers seeking an easy-to-set-up, lightweight split king with cooling features and versatile comfort.
Not ideal for: Buyers who need a high-support, durable mattress for long-term heavy use or those seeking a softer feel.
- Size:Split King
- Thickness:10 inches
- Material:Gel Memory Foam, Foam
- Layers:2
- Weight:78 pounds
- Certifications:CertiPUR-US®, Oeko-Tex®
Our verdict“Ideal for hot sleepers who want quick, easy setup and cooling comfort in a lightweight split king, despite limited durability data.”

The Celestial Sleep 12-inch Split King offers a soft, plush feel with its four-layer design, emphasizing comfort and breathability. Compared with the Novilla Bliss 14-Inch Mattress, it has a slightly thinner profile but still provides multiple comfort layers and cooling features, making it suitable for side sleepers or those wanting a softer touch. Its made-in-USA certification and eco-friendly materials add appeal. The main drawback is its hand wash-only cover and potentially higher price due to certifications, which might be a concern for budget-conscious buyers. This mattress is best for those who prioritize plushness and long-term safety certifications, but less for those seeking a firmer or lighter option.
Pros:- Cooling gel bead infused memory foam for temperature regulation
- Supports all sleep positions with multiple comfort layers
- Made in the USA with certified safe, eco-friendly materials
- Supports various sleep positions with multiple comfort layers
Cons:- Hand wash only cover requires extra care

- Thickness:12 inches
- Material:Gel Memory Foam, Memory Foam, Polycotton

Amada Split King Adjustable Bed Frame and 14 Inch Cooling Gel Memory Foam Mattress Set with Massage and Remote
This setup stands out for combining a highly versatile adjustable base with a 14-inch cooling gel memory foam mattress that emphasizes personalized comfort. Compared to the Celestial Sleep 8 Inch model, the Amada set offers greater adjustability, including head and foot angles, along with built-in massage functions, making it ideal for those who prioritize tailored positioning and relaxation features. The mattress’s breathable graphene cover helps keep you cool, but the separate delivery of base and mattress can delay setup, and assembly instructions might feel sparse for some users. Its support for up to 750 lbs and multiple height options add to its appeal for heavier or taller sleepers seeking an all-in-one sleep solution.
Pros:- Fully adjustable head and foot positions for personalized comfort
- Built-in massage with multiple modes and adjustable intensity
- Includes USB ports, LED night light, and preset memory functions
- Breathable graphene-infused cover enhances cooling
Cons:- Separate delivery of bed frame and mattress can cause delays

The Celestial Sleep 8 Inch model excels in offering a straightforward, supportive mattress that’s easy to set up, especially compared to the Novilla Bliss 14 Inch. Its firm feel is ideal for sleepers who prefer a more supportive surface, but it lacks adjustable features or cooling technology beyond basic gel infusion. The heavy weight of 70 pounds might require assistance during setup, and limited info on durability or edge support could concern those seeking long-term reliability. Made with certified safe materials, it’s a reliable choice for buyers prioritizing safety and simplicity over advanced features.
Pros:- Easy setup with unboxing and unrolling process
- Made with CertiPUR-US® and Oeko-Tex® certified materials

Novilla Bliss Cooling King Size Mattress, 14 Inch Gel Memory Foam
The Novilla Bliss 14-inch mattress is designed to combat heat with NanoGEL memory foam and a cool-touch nylon cover, making it a strong choice for hot sleepers compared to the Celestial Sleep 8 Inch. Its triple-layer foam system offers pressure relief, spinal alignment, and durability, but its weight of over 91 pounds can complicate setup and movement.

Split King Medium Soft Cooling Gel Memory Foam Mattress – 14 Inch Breathable Comfort, Motion Isolation Mattress in a Box
This split king mattress offers a medium-soft feel with responsive gel-infused foam that balances pressure relief with support. It compares favorably to the Sweetnight CoolNest for its motion isolation and breathability, making it suitable for couples. However, its softer feel might not satisfy those who prefer firmer support, and long-term durability depends on proper care.

Sweetnight CoolNest 14 Inch King Size Mattress, Cooling Memory Foam Mattress
The CoolNest 14-inch mattress emphasizes zoned support with a layered cooling system that promotes pressure relief and temperature regulation. It’s comparable to the Novilla Bliss but adds a 5-zone design, making it particularly suited for those who want targeted support for different body areas. Its CertiPUR-US certification reassures safety, but the 86.6-pound weight can make moving or setup more challenging.

This Novilla 14-inch mattress stands out for its combination of cooling NanoGel-infused foam and multiple support layers, making it a versatile choice for those who want a balanced sleep experience. Compared with the 12-inch Novilla model, the extra thickness adds more pressure relief and spinal support, but it requires a longer 72-hour expansion period and is quite heavy at 82 pounds. Its CertiPUR-US certification guarantees safety, while its plush feel appeals to sleepers seeking softness. However, the weight and firmness may pose challenges for mobility and softer preferences. This pick makes the most sense for individuals prioritizing cooling, support, and safety certifications in a larger size.

Unlike the 14-inch model, it provides a slightly softer profile, though it still maintains a medium plush feel that supports spinal alignment. Its lightweight of around 78 pounds makes setup easier, and both CertiPUR-US and OEKO-TEX certifications ensure safety. However, it shares the same 72-hour expansion window, which could be inconvenient. The focus on temperature regulation and motion isolation makes it well-suited for couples or hot sleepers, but those seeking a thicker, more cushioned surface might prefer the 14-inch version. This mattress is a smart pick for those who prioritize cooling and safety certifications in a manageable size.

Factors to Consider When Choosing Split King Memory Foam Mattress
Choosing the right split king memory foam mattress involves weighing several important factors. Beyond price, consider how firmness levels suit your comfort preferences, especially since split king models often allow for different sides. Cooling features can make a big difference if you tend to sleep hot, so look for gel-infused foams or breathable covers. Compatibility with adjustable bases is another critical consideration if you want adjustable support or massage features. Durability and certifications provide peace of mind about safety and longevity. Avoid common pitfalls like choosing a mattress based solely on price or ignoring construction quality, which can lead to discomfort or early wear.Firmness and Comfort Customization
Since split king mattresses often feature two separate halves, they provide an opportunity to customize firmness on each side. Consider whether you prefer a softer, medium, or firmer feel, and verify that the mattress allows for different firmness options if needed. This flexibility can significantly improve sleep quality for couples with different preferences, but it also means you should check if the mattress supports these variations without sacrificing support or durability. Overly plush or overly firm options may lead to discomfort or pressure points, so testing or reading reviews about the actual feel is essential.
Cooling and Breathability
If you tend to sleep hot, prioritizing cooling features is vital. Gel-infused memory foam, breathable covers, and open-cell structures can help dissipate heat. However, not all cooling features are equally effective, and some may add to the cost. Avoid models that lack adequate airflow, especially if you live in a warm climate or use a heated bed. Remember, cooling is a key factor for restful sleep and can offset the potential heat retention issues often associated with memory foam.
Compatibility with Adjustable Bases
Many split king mattresses are designed to work with adjustable bed frames, which can enhance comfort through customizable positioning and massage features. Ensure that the mattress is rated as flexible enough to bend with an adjustable base without damage. Not all foam mattresses are suitable for frequent bending, so check manufacturer guidelines before purchasing if you plan to use an adjustable frame. Compatibility can also influence the mattress’s lifespan and warranty coverage, so it’s worth verifying in advance.
Durability and Material Quality
Memory foam quality varies, impacting how long the mattress maintains its support and comfort. Look for certifying labels like CertiPUR-US® and Oeko-Tex® to confirm safety and quality standards. The density of the foam—measured in pounds per cubic foot—also indicates durability; higher density generally lasts longer. Avoid overly soft or low-density foams that may compress quickly, leading to sagging and discomfort. Investing in a well-made mattress can save money over time by reducing the need for early replacement.
Price and Value Considerations
Split king memory foam mattresses span a broad price range, from budget-friendly options to high-end models with advanced features. Balance your budget with the features you need most—such as cooling, firmness flexibility, or adjustable compatibility. Cheaper models may lack durability or cooling, while premium options often include additional perks like massage functions or enhanced breathability. Consider how long you plan to keep the mattress and whether the added features justify the higher cost, especially since a split king is an investment in long-term sleep quality.
Frequently Asked Questions
Can I use a split king memory foam mattress with any adjustable bed frame?
Most split king memory foam mattresses are compatible with adjustable bases, but it’s important to verify each model’s flexibility. Look for products explicitly rated as adjustable-base friendly, which can bend without damage and support the frame’s movements. Not all foam mattresses are designed to handle repeated bending, especially those with dense foam layers that may crack or warp. Checking manufacturer recommendations and reviews can help you avoid issues and ensure your mattress lasts as long as the bed frame’s capabilities.
Is a cooling gel memory foam mattress worth the extra cost?
Cooling gel memory foam mattresses can significantly improve sleep for hot sleepers by dissipating heat more effectively than standard foam. While they tend to be priced higher, the investment can lead to better sleep quality and fewer nighttime wake-ups due to overheating. If you naturally sleep hot or live in a warm climate, opting for a gel-infused model is often justified, but for cooler sleepers, a standard foam mattress may suffice. Always consider your personal thermal comfort and whether the cooling features align with your sleep environment.
How important are certifications like CertiPUR-US® when choosing a memory foam mattress?
Certifications such as CertiPUR-US® and Oeko-Tex® indicate that the foam has been tested for safety, low emissions, and environmental impact. Choosing certified mattresses reduces the risk of exposure to harmful chemicals, providing peace of mind especially if you have sensitivities or allergies. These labels also suggest better manufacturing standards, which can correlate with longer-lasting support and comfort. While certification alone isn’t a guarantee of quality, it is a reliable indicator that the mattress meets certain safety criteria.
What firmess level should I choose if I sleep with a partner with different preferences?
Split king mattresses typically allow each side to have a different firmness level, which is ideal for couples with varying comfort needs. If you share a bed with a partner, consider a medium or medium-firm setting as a versatile choice that suits most sleepers. For more personalized comfort, look for models that support independent firmness adjustments on each side. This approach minimizes compromise and can improve sleep quality for both, but ensure the mattress construction supports such customization without sacrificing durability.
What should I look for to ensure a split king mattress will last over time?
Durability depends heavily on foam quality, construction, and proper care. Prioritize high-density foam layers, which resist sagging and indentations longer. Check for reputable certifications and read customer reviews about longevity. Additionally, consider the warranty—longer warranties often indicate confidence in the product’s lifespan.
