Our Picks: Best Memory Foam Mattress With Cooling Technology reviews
1. Novilla 12-Inch Queen Mattress: Balanced Cooling and Comfort
This 12-inch queen mattress uses three foam layers, including NanoGel memory foam, comfort foam, and a high-density support layer. Novilla says the gel is intended to absorb heat, while the breathable knitted cover supports airflow. The foam construction also aims to ease pressure and limit movement transfer across the bed.
The listed feel is medium plush, which may suit sleepers who want some contouring without choosing a mattress described as firm. The design may be useful for couples who are easily disturbed by movement, though an all-foam build can feel different from a spring mattress. The listed maximum weight capacity is 500 pounds, so check that it fits your household’s needs.
All foams are listed as CertiPUR-US certified, and the cover is listed as OEKO-TEX Standard 100 certified. The mattress arrives compressed and is recommended to air out and reshape for up to 72 hours. That setup time is worth planning for if you need to use the bed right away.
Pros:
- NanoGel foam and a breathable cover are designed to help manage heat.
- Three-layer foam construction targets pressure relief and motion isolation.
- CertiPUR-US foam and an OEKO-TEX Standard 100 certified cover.
- Includes a 10-year protection period.
Cons:
- May need up to 72 hours to air out and fully reshape.
- The listed maximum weight capacity is lower than that of the COOL GEL models.
Verdict: Choose this Novilla if you want a queen-size, medium-plush foam mattress with cooling-focused materials and motion isolation.
2. COOL GEL Chill 14-Inch King: A Thicker, Contouring Option
This king-size COOL GEL Chill has a 14-inch profile and multiple layers of cooling gel memory foam. Its deeper build is designed to offer more cushioning and body contouring, while the foam construction helps limit motion transfer. The product description highlights pressure relief around areas such as the shoulders, hips, and back.
There is a firmness detail to consider: the product information lists the mattress as firm, while the description emphasizes a plush, cushioned feel. Firmness is subjective, so if you strongly prefer either a very firm or very soft bed, review the listing details carefully before choosing. It comes with two pillows, which may be a useful extra for setting up a bed.
The mattress is described as fiberglass-free and made with CertiPUR-US certified foam. It is compressed for delivery and may need up to 72 hours to expand. The listed compatibility includes platform beds, slatted frames, box springs, and adjustable bases; the listed maximum weight capacity is 1,000 pounds.
Pros:
- 14-inch profile offers a more substantial foam surface.
- Cooling gel foam is designed to help dissipate heat.
- Motion isolation and body contouring may suit couples and pressure-sensitive sleepers.
- Includes two pillows and lists a fiberglass-free fire barrier.
Cons:
- The firm listing and plush-focused description may make the feel difficult to predict.
- Allow up to 72 hours for full expansion after unboxing.
Verdict: This is a strong option if you want a king-size, 14-inch foam mattress and are comfortable checking the firmness details before buying.
3. COOL GEL Chill 14-Inch Full: Deep Foam Comfort for Solo Sleepers
This full-size version shares the 14-inch height and cooling gel foam design of the king model. Its layered construction aims to contour to the body, relieve pressure, and reduce movement across the sleep surface. A full size can work well for one person who wants more room than a twin, while taking up less space than a king.
As with the king, the listed firmness is firm, but the product copy also describes the mattress as plush and cushioned. That difference is important if firmness is a deciding factor for you. This model includes one pillow, rather than the two listed with the king version.
The product information lists CertiPUR-US certified foam and a fiberglass-free fire barrier. It is compatible with several common bed bases, including platform beds and adjustable bases. Allow up to 72 hours for the compressed mattress to expand fully, and note that the listed maximum weight capacity is 1,000 pounds.
Pros:
- 14-inch profile provides a deeper foam feel in a full size.
- Gel memory foam is designed to help manage heat and pressure.
- Foam construction aims to reduce motion transfer.
- Includes one pillow and lists a fiberglass-free fire barrier.
Cons:
- Firmness wording may be confusing for shoppers seeking a precise feel.
- May take up to 72 hours to fully expand after unboxing.
Verdict: Pick this full-size model if you want a thick, contouring foam mattress for one sleeper and are willing to confirm that its listed firmness suits you.
4. Novilla Bliss 12-Inch Full: Cooling Foam With Reinforced Edges
The Novilla Bliss combines NanoGel memory foam with comfort and support layers in a 12-inch full-size mattress. The gel foam is intended to dissipate heat, and the soft knitted cover is designed to support airflow. Its three-layer design also aims to distribute body weight, ease pressure, and reduce movement transfer.
One detail that sets this model apart from the other full-size pick is its reinforced edge support. That may be helpful if you sit or sleep near the edge of the mattress, though it remains an all-foam design rather than a coil mattress. The product description also notes plant-infused fiber in the comfort foam for odor absorption.
The foam is listed as CertiPUR-US certified, and the product information mentions ACA and ISPA certifications. It arrives compressed, with up to 72 hours suggested for it to regain its shape. The stated offer includes a 100-day trial and 10-year protection, but check the listing for the current terms and conditions.
Pros:
- NanoGel foam and a breathable cover are designed for cooling comfort.
- Reinforced edges may provide added stability near the sides.
- Three foam layers aim to ease pressure and limit motion transfer.
- Includes a stated 100-day trial and 10-year protection period.
Cons:
- May need up to 72 hours to fully regain its shape.
- The product details do not specify a firmness level.
Verdict: Consider the Novilla Bliss if you need a full-size foam mattress with cooling-focused materials and added edge support.
5. SLEEP100 12-Inch Firm King: A More Supportive, Stable Feel
This 12-inch king mattress is designed for sleepers who prefer a firmer surface with less sink. Its gel memory foam and breathable knit cover are intended to help reduce heat buildup, while the high-density support core aims to keep the surface stable. The spring-free construction also absorbs movement, which may be useful for couples or light sleepers.
The foam is listed as CertiPUR-US certified, and the fabric is described as OEKO-TEX tested. The mattress is also described as fiberglass-free. The listing says it works with most bed frames, including platform beds and adjustable bases, and offers a 365-night trial. Check the product listing for the details and conditions of that trial before purchasing.
The setup instructions state that the mattress arrives compressed and may expand in two to 12 hours. Firmness can feel different from one sleeper to another, and some owners find that the mattress feels firmer after it has fully expanded. If you want a plush, deep-sinking feel, the firm design may not be the best match.
Pros:
- Firm construction aims to limit excessive sinkage.
- Gel foam and a breathable cover are designed to help with heat management.
- Motion-isolating, spring-free design may suit couples.
- Lists a 365-night trial and fiberglass-free materials.
Cons:
- May feel too firm for sleepers who prefer a plush surface.
- Listed trial terms should be checked before ordering.
Verdict: Choose the SLEEP100 if you want a firm king mattress with gel foam and a stable, low-sink feel.
How to Choose a Cooling Memory Foam Mattress
Look at the type of cooling features
Gel-infused foam, NanoGel foam, and breathable knit covers are all intended to help manage heat, but they work as part of the mattress design rather than as active cooling systems. If you tend to sleep hot, compare the foam materials and cover construction, and remember that bedding, room temperature, and personal comfort also affect how cool a mattress feels.
Match firmness to your preferred feel
Firmness descriptions are not always consistent. The COOL GEL models are listed as firm, while their product descriptions also emphasize plush cushioning. If you like a softer, contouring surface, look closely at how the mattress is described and check the seller’s current details. If you prefer less sinkage, the SLEEP100 is the clearest firm option in this group, while the queen Novilla is listed as medium plush.
Consider pressure relief and support together
Memory foam can contour around pressure points, while a support layer helps keep the body from sinking too far. Your preferred balance may depend on your sleeping position, body shape, and comfort needs. A mattress that feels supportive to one person may feel too firm or too soft to another, so look for a clear firmness description and a trial policy that fits your needs.
Choose the right height and size
The mattresses here range from 12 to 14 inches tall. A thicker profile may feel more substantial and can affect how high the bed sits, so check your frame and bedding. Choose the mattress size based on the room available and whether you sleep alone or share the bed. The two COOL GEL models also differ in included pillows: the king lists two, while the full lists one.
Check your bed frame and setup needs
Boxed mattresses arrive compressed and need time to expand. Follow the instructions for the specific model: the Novilla mattresses and COOL GEL models suggest allowing up to 72 hours, while the SLEEP100 listing gives a shorter expansion estimate. Confirm the mattress is compatible with your base and plan for the weight and space needed to unbox it safely.
Review certifications, trial terms, and protection
Certifications can help you compare material standards, but they do not tell you whether a mattress will feel comfortable. The products in this list include different certifications and protection terms, so check each listing for exact coverage, eligibility rules, and return conditions. A trial period can be helpful when you are unsure about firmness, but read the full terms before ordering.
Frequently Asked Questions
Does gel memory foam keep a mattress cool all night?
Gel foam is designed to help dissipate heat, and breathable covers may support airflow. These features can help manage heat, but they do not guarantee that every sleeper will stay cool all night.
Which mattress in this list is the firmest?
The SLEEP100 is clearly described as firm and is designed to limit sinkage. The COOL GEL models are also listed as firm, but their descriptions emphasize a plush, cushioned feel, so check the product details if firmness is important to you.
Which option has the thickest profile?
Both COOL GEL Chill mattresses are 14 inches tall. The other listed models are 12 inches tall.
How long should I wait before sleeping on a boxed mattress?
Follow the setup directions for the mattress you choose. The Novilla and COOL GEL listings recommend allowing up to 72 hours for full expansion. The SLEEP100 listing gives an estimated expansion time of two to 12 hours.
Are these mattresses suitable for couples?
Several models describe motion isolation as a feature, which may help reduce movement transfer between sleepers. Consider the size of the mattress as well: a king offers more shared space than a full or queen.
Do all of these mattresses have removable covers?
The COOL GEL product details list a removable cover. The supplied descriptions for the other models do not confirm that their covers are removable, so check the listing before buying if that feature matters to you.
Final Recommendation
For a balanced option with a stated medium-plush feel, NanoGel foam, and a breathable cover, the Novilla 12-Inch Queen is a sensible place to start. Choose the Novilla Bliss if edge support is a priority, a COOL GEL model if you want a deeper 14-inch profile, or the SLEEP100 if you prefer a firmer king mattress. Compare firmness, setup time, size, and trial terms before making your final choice.
