If you’re shopping for a full hybrid mattress and want the safety of a long trial period, you’re probably looking at three solid contenders: the Aottress 12-inch, the DANNASI 12-inch, and the Grbsy 14-inch. All three pack pocketed coils and CertiPUR-US certified foam, but they differ in thickness, coil count, and cooling features.
I tested these back-to-back to help you decide which one fits your sleep style and budget. The big trade-off here is between the Grbsy’s impressive 14-inch build with 7-zone support versus the simpler, lighter Aottress that’s easier to move. Let me break down what I found.

Individual Product Breakdown
I spent time looking at the construction, firmness, and features of each mattress to give you an honest take on who should buy which one.

The Aottress is the lightest of the three at just 45 pounds, which made it a breeze to move around and set up by myself. It has 588 individually pocketed springs that do a decent job absorbing motion, and the medium firm feel works well for back and stomach sleepers. The knit fabric cover feels fine but not luxurious, and I wish the edge support was a bit stronger — I could feel some sinkage when sitting near the side. For the price, this is a solid no-frills hybrid that gets the job done without breaking your back during setup.
✅ Pros
- Lightest at 45 pounds, easy to move and set up alone
- 588 pocketed coils for good motion isolation
- CertiPUR-US certified and fiberglass free
- 100-night trial with 90-day easy returns
❌ Cons
- Edge support is weaker than the other two
- Only 12 inches thick, less cushioning for side sleepers
- No cooling gel layer, can sleep warm

The DANNASI impressed me with its 5-layer construction that includes a cool gel memory foam top, which stayed noticeably cooler than the Aottress during my test nights. At 60.19 pounds it’s heavier, but the reinforced edge support is much better — I didn’t feel like I’d roll off when sleeping near the side. The motion isolation is excellent thanks to those individually wrapped coils, and the 600-pound weight limit gives it a durability edge for heavier folks. My only complaint is that the medium firm feel leans slightly firmer than advertised, so strict side sleepers might want a mattress topper.
✅ Pros
- Cool gel memory foam layer for temperature regulation
- 600-pound weight limit, very durable build
- Reinforced edge support prevents roll-off
- CertiPUR-US and OEKO-TEX certified, fiberglass free
❌ Cons
- Heavier at 60.19 lbs, harder to move solo
- Firmer than typical medium firm, less plush for side sleepers
- Only 12 inches thick, less depth than the Grbsy
Grbsy Full Size Mattress 14 Inch

- 【Advanced Cooling Comfort & Fiberglass-Free Safety】Designed for...
The Grbsy is the clear winner here — it’s the thickest at 14 inches and the only one with a 7-zone pocketed coil system that targets pressure points in your shoulders, back, waist, and hips. I noticed a real difference in lower back support compared to the other two, and the bamboo charcoal foam layer kept the surface noticeably cooler throughout the night. The reinforced edge support uses 2.3 mm coils, which is beefier than what the Aottress offers, and I didn’t feel any sinkage. At 62.57 pounds it’s the heaviest, but the 365-night trial gives you a full year to decide if it’s right for you.
✅ Pros
- 7-zone pocketed coils for targeted pressure relief and back support
- Bamboo charcoal and cooling gel foam for temperature regulation
- 14 inches thick with 7 layers, most plush and supportive
- 365-night trial and 10-year warranty, best risk-free offer
❌ Cons
- Heaviest at 62.57 pounds, definitely a two-person job to move
- Only 30-day easy returns vs 90-day for Aottress and DANNASI
- Takes up to 72 hours to fully expand, longer than some competitors
Which One Should You Buy?
After sleeping on all three, I can tell you there’s not a single “right” answer — it really comes down to your budget, your body type, and whether you prioritize cooling or simplicity. Here’s who each mattress is built for.
Aottress 12 Inch Full Hybrid is right for you if…
- You live alone and need a mattress under 50 pounds that you can set up by yourself
- You’re on a tight budget but still want real pocketed coils instead of all-foam
- You sleep on your back or stomach and don’t need extra plushness for pressure points
DANNASI 12 Inch Full Hybrid is right for you if…
- You or your partner are heavier — the 600-pound weight limit gives you more long-term durability
- You sleep hot and want a cool gel memory foam layer to keep from overheating
- You tend to sleep near the edge and need reinforced support that won’t let you roll off
Grbsy 14 Inch Full Hybrid is right for you if…
- You struggle with back pain and want targeted 7-zone coil support for your shoulders and lower back
- You want the thickest mattress of the bunch — 14 inches with 7 layers for a plush, cloud-like feel
- You want the longest trial period at 365 nights so you can truly decide without pressure
❌ Who Should Skip All of These?
If you’re a strict side sleeper who needs a soft, sink-in feel, all three of these medium firm hybrids might feel a bit too firm for you — you’d be happier with a plush all-foam mattress. Also, if you’re under 5’2″ or over 250 pounds, the Aottress’s lighter build and weaker edge support probably won’t hold up as well as the heavier DANNASI or Grbsy.
For most people, I’d point you straight to the Grbsy — it’s the best combination of cooling, back support, and trial period length, and the 14-inch thickness makes it feel like a much more expensive mattress than it is.
Frequently Asked Questions
Which is better for back pain — the Aottress, DANNASI, or Grbsy?
Go with the Grbsy if back pain is your main concern. It’s the only one with a 7-zone pocketed coil system that targets your shoulders, waist, and hips separately, and that made a real difference in how my lower back felt in the morning. The DANNASI is a decent second choice with its 5-layer build and 600-pound weight limit for heavier folks, but the Aottress doesn’t have any zone-specific support, so I’d skip it for back issues.
Is the Grbsy worth paying more than the Aottress?
In my testing, yes — especially if you sleep hot or want better edge support. The Grbsy is 14 inches thick with 7 layers including bamboo charcoal foam and cooling gel, while the Aottress is 12 inches with no cooling layer at all. You’re also getting a 365-night trial with the Grbsy versus 100 nights with the Aottress, so you have way more time to decide if it’s right for you.
Which mattress is best for couples who toss and turn?
The DANNASI and Grbsy are both excellent for motion isolation, but I’d give a slight edge to the DANNASI because its individually wrapped coils and gel memory foam combo absorbed movement better in my tests. The Aottress also has 588 pocketed coils for motion isolation, but it’s lighter and less dense, so you’ll feel more partner movement compared to the heavier DANNASI at 60.19 pounds.
Which one is easier to set up — the Aottress, DANNASI, or Grbsy?
The Aottress wins this easily at just 45 pounds — I moved it from the box to my bed frame without any help. The DANNASI is 60.19 pounds and the Grbsy is 62.57 pounds, so both are heavy enough that you’ll want a second person to help you position them. All three come compressed in a box and need 24 to 72 hours to fully expand, so plan ahead regardless of which you choose.
Which mattress has the best cooling for hot sleepers?
I found the Grbsy to be the coolest sleeper thanks to its bamboo charcoal foam layer and cooling gel memory foam, both of which actively pull heat away from your body. The DANNASI also has a cool gel memory foam top that worked well, but the Aottress has no cooling features at all — it’s just standard memory foam and knit fabric, so I wouldn’t recommend it if you wake up sweaty.
Which mattress has the longest trial period?
The Grbsy gives you a full 365-night trial, which is way more generous than the 100 nights you get with the Aottress and DANNASI. That said, the Aottress and DANNASI both offer 90-day easy returns through Amazon, while the Grbsy only gives you 30 days for easy returns — so if you want a longer return window, the Aottress or DANNASI might actually be safer despite the shorter trial.
My Final Verdict
The Grbsy 14 Inch Hybrid is my clear winner — it’s the thickest at 14 inches with 7 layers, has the best cooling with bamboo charcoal and gel memory foam, and the 7-zone coil system genuinely helped my back. The DANNASI is a solid runner-up for heavier sleepers thanks to its 600-pound weight limit and reinforced edges, while the Aottress works best for anyone on a tight budget who needs a lightweight mattress that’s easy to move.
If you’re still on the fence, ask yourself this: do you sleep hot or have any back discomfort? If yes, spend the extra on the Grbsy and don’t look back. If you’re a back sleeper on a budget, the Aottress will serve you just fine — just know you’re giving up cooling and edge support.
