Our Picks: Best 12 Inch Cool Gel Memory Foam Mattress Queen reviews
Best Price Mattress 12-Inch: A Medium-Firm, Straightforward Gel Option
This Best Price Mattress model is a 12-inch, medium-firm memory foam mattress with gel-infused foam. Its design aims to adapt to your body while easing pressure, with a breathable construction intended to support airflow. The medium-firm feel makes it a potential fit if you want cushioning without choosing the plushest option in this group.
The mattress ships compressed, which can make delivery and room setup more manageable. The product information says to allow up to 72 hours for it to expand to full size after opening. Plan for that waiting period before judging its final shape and feel.
Its main strength is a simple combination of gel foam, pressure relief, and medium-firm support. The supplied details do not name a specific foam certification, however, so shoppers who want a particular certification should confirm the current product information before buying. Compared with the other picks, this one provides fewer specifics about its foam-layer layout.
Pros:
- Medium-firm feel balances cushioning and support.
- Gel-infused foam is designed to help regulate temperature.
- Breathable construction is intended to promote airflow.
- Ships compressed for more convenient setup.
Cons:

COOL GEL 12-Inch Queen Mattress: Open-Cell Design for Medium-Firm Support
The COOL GEL queen mattress pairs a high-density foam base with a breathable comfort layer. Its medium-firm design is intended to contour around pressure points while supporting spinal alignment. The listing describes it as suitable for back, side, and stomach sleepers, though your comfort will depend on your build and preferred firmness.
Its open-cell foam structure is designed to support airflow and heat dissipation. The product information also identifies the foam as CertiPUR-US certified and says the mattress is fiberglass-free. It is listed as made in the USA and measures 60 by 80 inches by 12 inches.
Compared with the Best Price Mattress, this option provides more detail about its foam base and certifications. The cooling features may help with airflow, but foam construction and bedroom conditions can still affect how warm a mattress feels. The supplied information does not specify a break-in period or expansion timeline.
Pros:
- Medium-firm support is designed for several sleeping positions.
- Open-cell construction is intended to improve airflow.
- CertiPUR-US certified foam and a fiberglass-free claim are listed.
- Queen dimensions are clearly specified.
Cons:
- Open-cell foam cannot guarantee that every sleeper will feel cool.
- The supplied details do not give an expansion timeline.
Verdict: This is a strong option if you want a medium-firm queen mattress with clearly described open-cell foam and listed certification details.
Novilla NanoGel 12-Inch Queen Mattress: A Focus on Airflow and Motion Absorption
This Novilla mattress uses three foam layers, including gel memory foam and high-density support foam. The product description says its NanoGel formulation has 30% more NanoGel, which is intended to absorb heat and promote airflow. It also describes the foam as helping reduce pressure points and absorb motion from a partner’s movement.
The mattress has a breathable knitted cover, and the listing identifies its foam as CertiPUR-US certified and its cover as OEKO-TEX Standard 100 certified. Those details give shoppers more information about the materials than some of the simpler listings in this roundup. Novilla also lists 10-year protection.
It arrives vacuum-compressed in a box and is described as fitting different bed frames, including use on the floor. The manufacturer recommends allowing 72 hours for it to air out and reshape. As with any foam mattress, the cooling claims are best treated as design goals rather than a promise that it will feel cool to everyone.
Pros:
- Three foam layers combine contouring with a high-density support base.
- Designed to absorb motion and reduce sleep disturbance from movement.
- CertiPUR-US foam and an OEKO-TEX Standard 100 cover are listed.
- Includes 10-year protection according to the product information.
Cons:
- Requires up to 72 hours to air out and reshape.
- The NanoGel cooling description does not guarantee a cool feel for every sleeper.
Verdict: Consider this Novilla if material certifications, motion absorption, and a three-layer design matter more to you than a specifically stated firmness level.
Novilla 12-Inch Queen Mattress with Reinforced Edges: Pressure Relief and Added Edge Support
This 12-inch Novilla is built around gel-infused memory foam and multiple foam layers. The product description says the mattress is designed to distribute weight, support spinal alignment, and ease pressure around the hips, shoulders, and lower back. It also highlights motion absorption, which can be useful if movement from a partner tends to disturb your sleep.
A soft knitted cover and gel-infused top layer are intended to support airflow and reduce heat buildup. The listing also calls out reinforced edge support, a feature that may matter if you sit or sleep near the edge. Its foam is listed as CertiPUR-US certified, and Novilla specifies 10-year protection and a 100-day free trial.
This pick offers more explicit edge-support and trial details than the other Novilla model in this roundup. However, the description does not state a firm or plush feel, so shoppers who know they need a particular firmness may want to check the current listing closely. The mattress is compressed for delivery, with up to 72 hours recommended for full expansion.
Pros:
- Gel foam and multiple layers are designed for pressure relief and support.
- Reinforced edges are called out for people who use the mattress perimeter.
- CertiPUR-US certified foam is listed.
- Includes a stated 100-day trial and 10-year protection.
Cons:
- The product details do not state a specific firmness level.
- Allow up to 72 hours for the mattress to fully expand.
Verdict: Choose this Novilla if edge support, pressure relief, and a stated trial period are priorities, but verify that its feel suits your firmness preference.
LUCID 12-Inch Gel Memory Foam Mattress: A Plush Choice for Side Sleepers
LUCID takes a softer approach than the medium-firm mattresses in this group. This 12-inch model has a medium-plush feel, with 3 inches of gel foam, a 1.5-inch transition layer, and a 7.5-inch high-density base. Its deeper comfort layers are designed to contour around the body, with the product description highlighting pressure relief at the hips and shoulders for side sleepers.
The comfort foam includes gel, while bamboo charcoal is described as helping absorb moisture and regulate temperature. The mattress is listed as fiberglass-free, with CertiPUR-US certified foam and a 10-year limited warranty. It is made in the USA with global and U.S. parts.
LUCID says this mattress works with adjustable bases, platform frames, and slatted frames, and that no box spring is needed. Its plush feel may be less suitable if you prefer a firm, level surface or dislike sinking into foam. Compared with the medium-firm picks, it is the clearest choice here for shoppers seeking a softer, more contouring feel.
Pros:
- Medium-plush feel and generous comfort layers suit shoppers seeking more contouring.
- Gel foam and bamboo charcoal are included in the comfort design.
- Listed as fiberglass-free, with CertiPUR-US certified foam.
- Compatible with adjustable bases and several frame types; no box spring needed.
Cons:
- Its plush feel may not suit sleepers who prefer firm support.
- The deeper foam comfort layers may feel too enveloping for some people.
Verdict: Pick the LUCID if you want a softer, more cushioning mattress, especially if you sleep on your side and prefer a plush feel over medium-firm support.
How to Choose a 12-Inch Cool Gel Memory Foam Queen Mattress
Match the firmness to your sleep position
Firmness is one of the most important choices because gel does not determine how soft or supportive a mattress feels. Side sleepers often look for enough cushioning around the shoulders and hips, while back and stomach sleepers may prefer a more supportive, less plush surface. The COOL GEL and Best Price Mattress models are described as medium firm; LUCID is medium plush. The Novilla options do not provide a specific firmness label in the supplied details.
Think of cooling features as design details, not a guarantee
Gel infusions, open-cell foam, and breathable covers are intended to manage heat or improve airflow. These features may be worth considering if you sleep warm, but they do not guarantee a cool feel. Your bedding, room temperature, and personal comfort can also affect how warm a foam mattress feels.
Check the foam layers and support construction
A mattress description that names its layers can help you understand how it may feel. LUCID lists its comfort, transition, and base foam thicknesses, while the NanoGel Novilla describes a three-layer construction with high-density support foam. If a listing does not explain the layer layout, avoid assuming it will feel or respond like a mattress with a detailed design.
Review certifications and material claims
Certifications can help you compare material and emissions information. The COOL GEL and LUCID listings identify CertiPUR-US certified foam, and both Novilla models do as well. One Novilla also lists an OEKO-TEX Standard 100 cover. Certification details are not included for the Best Price Mattress in the supplied information, so check the product listing if that matters to you.
Confirm frame compatibility and setup needs
Mattresses that ship compressed can be easier to move into a room, but they need time to expand after opening. The Best Price Mattress and both Novilla models specify a 72-hour expansion or reshaping period. LUCID lists compatibility with adjustable bases, platform frames, and slatted frames, and says a box spring is not needed. Check the current product details for any setup instructions that apply to your chosen model.
Compare trial and warranty terms carefully
Coverage and trial terms can differ, so read the current listing and seller policies before ordering. One Novilla listing states 10-year protection and a 100-day trial; the other states 10-year protection. LUCID lists a 10-year limited warranty. These terms are not the same as a promise that a mattress will suit every sleeper, so confirm the conditions that apply to returns and claims.
Frequently Asked Questions
Is a gel memory foam mattress guaranteed to sleep cool?

How long should I wait before sleeping on a mattress in a box?
Follow the instructions for your specific mattress. The Best Price Mattress and both Novilla listings recommend allowing up to 72 hours for expansion or reshaping. The supplied details for the COOL GEL and LUCID models do not give the same timeline.
Are the mattresses listed as CertiPUR-US certified?
The COOL GEL, both Novilla, and LUCID product descriptions identify their foam as CertiPUR-US certified. The supplied Best Price Mattress details refer to certified safe foams and fabric but do not name a specific certification.

Final Recommendation
For a clearly described medium-firm feel and open-cell construction, the COOL GEL 12-Inch Queen Mattress is a practical starting point.
