by Coolsense, 10 Gel Memory Foam, is a fantastic all-foam mattress that keeps you cool and comfy all night. This two-layer mattress contains memory foam laced with NUGEL® and a 7″ base support form. The gel keeps the bed cool, while the second layer supports a restful night’s sleep. However, this mattress is not widely available and might be difficult to get online and in shops.
Thus, our top recommendation is the Loom and leaf Saatva mattress, a superior alternative to the cool sense mattress. It has a supportive and cooling design. CertiPUR-US foams give pressure relief and stability, while gel infusions keep you cool and provide lower back support. In addition, the mattress comes in two firmness options at no extra cost.

The #1 alternative we recommend — Amerisleep AS3
Amerisleep AS3 — medium hybrid
After putting the AS3 through our 21-night Sleep Lab protocol, this is the mattress we point most Coolsense 10 Gel Memory Foam shoppers toward when they ask “what should I buy instead?” Bio-Pur plant-based memory foam handles heat and pressure relief better than the cheap foam in the Coolsense 10 Gel Memory Foam, and HIVE 5-zone targeted support keeps the lumbar from sagging the way budget foam cores do over time. 100-night home trial. 20-year non-prorated warranty.

Step up — foam-on-coil hybrid for side sleepers
Amerisleep AS5 Hybrid — soft-medium for shoulder pressure relief
If you sleep mainly on your side or have shoulder pressure issues, the AS5 Hybrid sits one step softer than the AS3 and pairs Active Flex transition foam over pocketed coils for deeper cradle without sinkage. Same 100-night home trial and 20-year non-prorated warranty as the AS3.
For shoppers who prefer all-foam luxury, the Saatva Contour5 (queen $3,049 with current $400 off) is a comparable secondary alternative — 5 lb high-density memory foam with a gel-infused cooling layer and 365-night home trial.
What We Like
- Luxury innerspring with excellent lumbar support
- Multiple firmness options available
- Free white-glove delivery and mattress removal
- 365-night trial and lifetime warranty
What Could Be Better
- Higher price than many online brands
- Heavier than foam mattresses
- Not compressed in a box
- Some off-gassing possible initially
Who We Recommend Coolsense Gel Memory Foam Mattress For:
- Back sleepers who prefer a smooth touch will appreciate the coolsense memory foam mattress. Its gel-infused memory foam layer does an excellent job cushioning the lower back region for added pressure relief.
- This mattress is ideal for anyone who enjoys the feel of memory foam. It incorporates a substantial amount of dense memory foam to provide the desired hug-like sensation.
- This is the best option for someone who tends to get too hot on their mattress. The NUGEL-infused memory foam layer provides excellent thermal management to help you sleep much better.
- If you share your mattress with your partner, this mattress is ideal since it efficiently limits motion transmission.
Avoid Coolsense Gel Memory Foam Mattress if:
- Since it only comes in medium firmness, this bed is unsuitable for folks who want many firmness alternatives.
- It is not ideal for persons who often sit or sleep near the bed's edge since it lacks additional edge support.
- If you desire a responsive, bouncy sensation in your bed, this one is not for you. This bed lacks springs and is, therefore, not a responsive bed.
Comfort & Firmness
The Coolsense 10 Gel Memory Foam Mattress comes in a medium firmness option. The medium firmness of this mattress is appropriate for most sleepers, excluding stomach sleepers. In addition, this mattress's comfort layer minimizes back discomfort or other aches and pains by cradling the body.
The Amerisleep AS3 is the firmness pick we recommend — medium support that suits most sleep positions, with HIVE zoning that firms up under the lumbar and softens at the shoulders. If you specifically want a softer or firmer feel, the Amerisleep range (AS1 firm through AS5 soft) lets you fine-tune without leaving the lineup.
Performance
The Mattress has a wonderful feel and provides comfortable cushioning throughout the night. Despite its medium-firm firmness level, it gives a lot of support, making it a good choice for most people. Despite being made of foam, the mattress does an excellent job keeping you cool.
Is it a Good Mattress for Back Pain?
The Coolsense 10 Gel Memory Foam Mattress' medium firmness and body-hugging foam help relieve back pain. Gentle hugging prevents the weight from accumulating in your lower spine, preventing back issues.
This is of utmost significance if you sleep on either side or back. However, stomach sleepers with back issues would find this design to be too soft. As a result, we recommend the Amerisleep AS2 (firm) over the AS3 for stomach sleepers with back pain — the firmer Bio-Pur layer keeps the hips from over-sinking, which is the main back-pain trigger for stomach sleepers.
Sagging & Edge Support
The Coolsense 10 Gel Memory Foam Mattress includes a strong foundation foam layer, making it more durable and less prone to sag than other memory foam mattresses. This mattress, however, falls short of providing enough edge support.
This may be a problem for those who sleep close to the edge or have trouble getting in and out of the mattress. The Amerisleep AS3 Hybrid, on the other hand, has reinforced perimeter coils that hold up under edge weight. This strong edge support gives the mattress stability and endurance, making it excellent for partners and heavy sleepers.
Motion Isolation
Coolsense 10 Gel Memory Foam Mattress is an all-foam mattress with excellent motion isolation. Although the foam layers are gentler for pressure alleviation, they do not enable bed movement. So, couples with various sleeping cycles must be likely to rest well without bothering their partner.
Sleeping Position & Weight
The mattress' medium firmness is comfortable and supportive for side and back sleepers who weigh less than 230 pounds. Also, its soft memory foam will mold the bodies of these sleepers and give some lovely sinkage.
On the other hand, this mattress is not suitable for heavy or average-weight stomach sleepers. It will droop quickly for heavier people and will not give the stability required to sleep all night comfortably. So, the firmer Amerisleep AS2 is the pick we suggest for heavier sleepers — it holds up to body weight without the deep sink you get on a soft foam.
Breathability & Heat Transfer
Compared to other all-foam mattresses, this bed maintains excellent temperature neutrality and does not overheat. Temperature control begins with a cool-to-the-touch spandex and polyester mix cover.
The phase-change component of the NUGEL-infused foam intensifies this even further. Every night, these materials let hot sleepers sleep peacefully and without overheating.
Durability
The Coolsense 10 Gel Memory Foam Mattress can last five to six years before showing signs of wear. For maximum lifespan, rotate the bed from head to foot every few months and use a mattress protector.
However, if you want something that will outlast the Coolsense by a decade, the Amerisleep AS3 is the better buy. The Bio-Pur foam holds up better than budget gel memory foam, and the 20-year non-prorated warranty backs that durability claim in writing.
What is Coolsense Gel-Infused Memory Foam Mattress Made of?
The construction of a coolsense mattress consists of simply two layers of foam and no fiberglass.
- Cover: The mattress cover comprises absorbent polyester and spandex fabric. The antibacterial properties in this fabric will keep harmful microorganisms from growing on your sleep surface.
- Comfort layer: The 3 inches of NUGEL-infused foam create a cool-to-the-touch sensation. This memory foam cradles the body and ventilates to keep you cool and comfortable all night.
- Base layer: 7″ foundation support form layer gives additional support for a restful night's sleep.
Is Coolsense Gel-Infused Memory Foam Mattress Flippable?
No. Because of the top-to-bottom structure, you cannot flip this bed. Still, if wear is an issue, you may rotate 180 ° every few months.
Does Coolsense Gel Memory Foam Mattress Come in a Box?
Yes, it comes in a compact box for convenience; unpack, unroll, and wait until the mattress expands.
Is Coolsense 10 Gel Memory Foam Mattress Usable with an Adjustable Bed?
Yes, you can use an adjustable bed foundation with Coolsense 10 Gel Memory Foam Mattress.
Is Coolsense 10 Gel Memory Foam Mattress Made in the USA?
Yes, the Coolsense 10 Gel Memory Foam Mattress is manufactured and constructed in America.

Our Verdict
The Coolsense 10 Gel Memory Foam Mattress supports, stabilizes, and relieves pressure where needed to promote sleep. It has considerable cooling advantages for those who sleep hot.
Couples love this mattress since it is motion-isolating and particularly well-liked by them. Overall, it's an excellent all-foam mattress lasting 5 to 6 years while providing support and relaxation. However, the Amerisleep AS3 is the upgrade pick — the Bio-Pur foam and HIVE-zoned base hold their shape longer than budget memory foam, and the 20-year non-prorated warranty backs that durability.
CoolSense 10" Gel Memory Foam: Budget Cooling Foam Review
CoolSense offers a 10-inch gel memory foam mattress in the budget category ($250–$450 Queen).

What You Get
- Height: 10 inches
- Comfort: Gel-infused memory foam top layer
- Support: High-density polyfoam base
- Cooling reality: Modest, temporary surface cooling
For genuine cooling: top cooling mattresses | lifespan expectations.

“Thermal regulation during sleep is clinically significant — elevated surface temperature disrupts sleep architecture and reduces deep sleep duration, which has downstream effects on tissue repair and pain sensitivity. Bio-Pur's open-cell structure dissipates heat faster than conventional viscoelastic, which is why the AS3 performs better for hot sleepers than most memory-foam alternatives. — Dr. Jordan Burns, DC, MS, Amerisleep Expert Review Board”
