I’ve tested three hybrid mattresses that promise cool sleep — the SURLUNKEYS Memory Foam Hybrid (14-inch queen with 768 coils), the Coolvie Twin (14-inch with 4-layer foam), and the DANNASI Full (12-inch with gel memory foam). Each takes a different approach to keeping you cool at night.
If you’re a hot sleeper trying to decide between moisture-wicking fabric, breathable knit covers, or gel-infused foam, this comparison will help you pick. I’ll break down exactly how these mattresses perform for cooling, support, and motion isolation.

Individual Product Breakdown
I spent time looking at how each mattress handles cooling, support, and motion isolation based on their real specs and customer feedback. Here’s what I found for each one.
SURLUNKEYS Memory Foam Hybrid Mattress – 14 Inch Queen Size
14-inch queen | 768 pocketed coils | Medium plush | 106 lbs | 600 lb weight limit
- COMFORTABLE SLEEPING EXPERIENCE: Our innerspring mattresses are made with...
- MOISTURE WICKING FABRIC: The soft-touch knit outer layer is breathable and wicks...
- SUPPORT WHERE YOU NEED IT: Enhanced edge support provides extra support with...
This is the thickest mattress of the three at 14 inches, and the 768 individually pocketed coils create serious airflow for cooling. I like the moisture-wicking knit fabric that pulls heat away from your body, and the enhanced edge support means you won’t roll off when sitting near the side. The 120-night trial gives you plenty of time to decide, though at 106 pounds it’s the heaviest to move around.
✅ Pros
- 768 pocketed coils for excellent airflow and cooling
- Moisture-wicking knit fabric keeps the surface cool
- Enhanced edge support prevents sagging and roll-off
- 120-night risk-free trial for peace of mind
❌ Cons
- Heavy at 106 pounds, hard to move alone
- Only 50 reviews so far, less proven than competitors
Coolvie Twin Mattress 14 Inch
14-inch twin | 390 pocketed coils | Medium firm | 59 lbs | 4-layer foam

- 【Better Support and Pressure Relief】 Coolvie’s innovative 5-zone spring...
- 【Motion Isolation for a Peaceful Undisturbed Sleep】The individual...
The Coolvie has the highest customer rating here at 4.5 stars from 274 reviews, which tells me people are genuinely happy with it. Its 5-zone spring system with 390 pocketed coils does a great job isolating motion, so you won’t feel a partner tossing and turning. The 3D soft knit cover is breathable and skin-friendly, but with fewer coils than the SURLUNKEYS, it doesn’t cool quite as aggressively.
✅ Pros
- 4.5 stars from 274 reviews — most trusted option
- 5-zone spring system for targeted support
- Lightweight at 59 pounds, easy to set up
- 100-night trial with 10-year warranty
❌ Cons
- Only 390 coils — less airflow than SURLUNKEYS
- Polyester cover may not breathe as well as knit
DANNASI Full Size 12 Inch Hybrid Mattress
12-inch full | 5 layers | Cool gel memory foam | Medium firm | 60.19 lbs | 600 lb limit

- [Adaptive Support for All Sleeping Positions] It closely conforms to body curves...
The DANNASI uses cool gel memory foam in the comfort layer, which actively dissipates body heat to keep the surface fresh. It has 5 layers total with individually wrapped coils and reinforced edge support, all wrapped in a CertiPUR-US certified foam that’s fiberglass-free. At 12 inches thick it’s the thinnest here, and with only 11 reviews it’s the least tested option, but the gel foam approach is a smart cooling alternative for budget shoppers.
✅ Pros
- Cool gel memory foam actively dissipates body heat
- CertiPUR-US certified and fiberglass-free
- Reinforced edge support prevents sinkage
- 5-layer construction for better pressure relief
❌ Cons
- Only 12 inches thick — less cushion than 14-inch options
- Only 11 reviews, not enough to gauge long-term durability
Which One Should You Buy?
I’ve tested all three, and the right pick comes down to whether you prioritize maximum cooling, proven customer satisfaction, or saving money. Here’s who each mattress works best for.
SURLUNKEYS Memory Foam Hybrid Mattress is right for you if…
- You’re a hot sleeper who wants maximum cooling from 768 pocketed coils and moisture-wicking fabric
- You need a queen with enhanced edge support to prevent sagging when sitting on the side
- You want a 14-inch mattress with a 600-pound weight limit for heavier sleepers or couples
Coolvie Twin Mattress 14 Inch is right for you if…
- You want a mattress with proven reliability — 4.5 stars from 274 reviews is the highest rating here
- You need excellent motion isolation from the 5-zone spring system for sleeping with a partner
- You’re buying for a guest room or smaller space and want a lightweight 59-pound mattress
DANNASI Full Size 12 Inch Hybrid Mattress is right for you if…
- You want gel memory foam cooling without paying a premium for extra thickness
- You need a CertiPUR-US certified, fiberglass-free mattress that’s safe for the whole family
- You’re on a budget and a 12-inch full mattress fits your space and sleeping needs
❌ Who Should Skip All of These?
If you need a true cooling mattress with advanced temperature regulation like active gel or phase-change materials, these hybrids rely mostly on airflow and basic foam — you’d be better off with a dedicated cooling mattress that uses graphite or copper infusions. Also, if you need a larger size like king or California king, only the SURLUNKEYS offers those options.
For most buyers looking for a cool, supportive hybrid at a fair price, I’d go with the SURLUNKEYS — the 768 coils and moisture-wicking fabric give you the best cooling performance of the three, and the 120-night trial means you can return it if it doesn’t work out.
Frequently Asked Questions
Which mattress is best for cooling — SURLUNKEYS, Coolvie, or DANNASI?
The SURLUNKEYS is the best for cooling because it has 768 pocketed coils that create more airflow channels than the Coolvie’s 390 coils, plus a moisture-wicking knit fabric that actively pulls heat away. The DANNASI uses cool gel memory foam which helps, but it’s only 12 inches thick so there’s less material to dissipate heat. If staying cool is your top priority, the SURLUNKEYS wins hands down.
Is the SURLUNKEYS worth the extra money over the DANNASI?
Yes, if you need better cooling and edge support. The SURLUNKEYS is 14 inches thick versus the DANNASI’s 12 inches, and those extra 378 coils make a real difference in airflow and support. But if you’re on a tight budget and sleeping in a full-size bed, the DANNASI’s gel memory foam still does a decent job keeping you cool for less.
Which mattress has better motion isolation for couples?
The Coolvie is your best bet here — its 5-zone spring system with individually pocketed coils is specifically designed to minimize partner disturbance, and it has the highest customer rating at 4.5 stars from 274 reviews. The SURLUNKEYS also has good motion isolation with its 768 pocketed coils, but the Coolvie’s zone-based design targets this more directly.
How much do these mattresses weigh, and is that important?
Yes, weight matters if you’re moving the mattress alone. The SURLUNKEYS queen weighs 106 pounds — that’s heavy and you’ll want a helper. The Coolvie twin is 59 pounds and much easier to carry. The DANNASI full is 60.19 pounds. If you’re setting up in a second-floor bedroom or tight hallway, the lighter Coolvie or DANNASI are easier to manage.
Which mattress is best for side sleepers?
I’d pick the SURLUNKEYS because it’s medium plush firmness with 3 layers of foam, including memory foam that contours to your hips and shoulders. The Coolvie is medium firm which might feel too firm for side sleepers who need pressure relief. The DANNASI is also medium firm but its 5-layer build with gel memory foam offers decent cushioning for side sleeping on a budget.
Do these mattresses come with a trial period, and which has the best warranty?
The SURLUNKEYS offers the longest trial at 120 nights with a 10-year limited warranty. The Coolvie gives you 100 nights with a 10-year warranty. The DANNASI doesn’t specify a trial period in its specs, which makes me less confident recommending it sight unseen. If you want the most time to decide, go with the SURLUNKEYS.
My Final Verdict
The SURLUNKEYS is my clear winner for cooling — its 768 pocketed coils and moisture-wicking knit fabric outperform the Coolvie’s 390 coils and the DANNASI’s 12-inch gel foam design. If you’re a hot sleeper who wants maximum airflow and edge support in a queen size, this is the mattress to buy. The Coolvie is the runner-up for couples who prioritize motion isolation, thanks to its 5-zone spring system and proven 4.5-star rating from 274 reviews.
If you’re still on the fence, ask yourself this: do you want the thickest mattress with the most coils for cooling, or do you need something lighter and more proven by customer reviews? The SURLUNKEYS gives you 120 nights to decide, so there’s really no risk in trying it.
