After weeks of tossing and turning on my old mattress, I finally decided to try something new. I ordered the DEHIJU Queen Size Mattress, 12 Inch Hybrid Memory Foam Queen Mattress in a Box and was honestly surprised by how it handled my partner’s restless sleeping.
This 12-inch thick mattress uses 500 pocketed coils and two layers of foam, including cooling gel memory foam. It’s best for couples who need motion isolation or anyone wanting medium firmness without the premium price tag. Just keep in mind the 100-night trial might feel short for some.

What Stands Out — Key Features
- Motion Isolation: The 500 independent pocketed coils really work. I can get up at night without waking my partner, and the mattress absorbs noise and vibration well.
- Cooling Gel Memory Foam: The top layer uses high-density open-cell gel foam that adapts to body temperature. I noticed less heat buildup compared to my old all-foam mattress.
- Medium Firmness: It hits a nice middle ground — not too soft, not too hard. The two-layer construction with pocket springs underneath provides balanced support for most sleep positions.
- Pressure Relief: The combination of gel memory foam and pocket springs distributes weight evenly from head to toe. My hip and shoulder pressure points felt noticeably better.
- Mattress in a Box: It arrived compressed in a box and expanded fully within a few hours. The 12-inch thickness is accurate, and the tight-top design stays clean-looking.
- CertiPUR-US Materials: The foam is made from safe, quality materials without harmful chemicals. The fabric cover is soft, skin-friendly, and resists pilling based on my first month of use.
- 100-Night Trial: DEHIJU offers a trial period so you can test it at home. While 100 nights is standard, it gives enough time to decide if the medium firmness works for you.

Pros & Cons — The Honest Take
✅ What I Like
- The 500 pocketed coils deliver excellent motion isolation — I can toss and turn without disturbing my partner even once.
- The gel memory foam top layer keeps me cool all night, thanks to the open-cell design that dissipates excess heat.
- At 12 inches thick with a medium firmness, it offers a balanced feel that works for back and side sleepers alike.
- The CertiPUR-US certified materials gave me peace of mind that the foam is safe and free from harmful chemicals.
- Setup was simple — it expanded to full queen size (60 inches wide) within a few hours after unboxing.
❌ What Could Be Better
- With only 14 customer reviews on Amazon, it’s tough to gauge long-term durability or common issues.
- The mattress has some initial off-gassing smell that took about two days to fully dissipate.
- The 100-night trial is standard, but I wish it were longer to really test whether the medium firmness holds up.
For me, the pros clearly outweigh the cons — the motion isolation and cooling features alone make it a solid choice for couples. Just be prepared for a brief smell period and check current price on Amazon to see if the value matches your budget.
⚖️ How Does It Compare?
I picked the DANNASI Full Size 12 and Coolvie Twin Mattress 14 as alternatives because they offer different sizes and thicknesses that might suit specific needs better than the DEHIJU queen. Let me break down how each stacks up against the 12-inch hybrid I tested.

- [All-Night Cool & Breathable Sleep Surface] The open-cell structure enhances air...
- [Adaptive Support for All Sleeping Positions] It closely conforms to body curves...
🔵 Alternative 1: DANNASI Full Size 12
Best for: Solo sleepers or guest rooms needing a full-size mattress with similar 12-inch thickness.
Key specs: Full size (54″W x 75″L) | 12 inches thick | Check listing for exact coil count and foam type
Where it beats the main product: The full size is more compact and easier to fit in smaller bedrooms or guest spaces than the queen DEHIJU.
Where it falls short: It likely lacks the 500 pocketed coil count of the DEHIJU, so motion isolation may not be as effective for couples.

⚪ Alternative 2: Coolvie Twin Mattress 14
Best for: Kids, teens, or single adults wanting a thicker 14-inch mattress in a twin size.
Key specs: Twin size (39″W x 75″L) | 14 inches thick | Check listing for foam density and coil type
Where it beats the main product: The extra 2 inches of thickness (14 vs 12) provides more cushioning for lighter individuals who prefer a plush feel.
Where it falls short: The twin size is only 39 inches wide, so it won’t work for couples or anyone needing queen-size space like the DEHIJU offers.
If you need a full-size mattress for a single person or guest room, the DANNASI is a solid budget-friendly pick, but the DEHIJU’s 500 coils give better motion isolation for couples. For a child or teen’s room, the Coolvie’s 14-inch thickness adds extra comfort, though you lose the queen width and cooling gel foam of the DEHIJU. Honestly, I’d stick with the DEHIJU queen if you share a bed and want that balanced medium feel with proven cooling features.
How It Actually Performs
Motion Isolation — The Quiet Night Test
I put the 500 pocketed coils to the test by having my partner get up and move around while I tried to sleep. The motion isolation is genuinely impressive — I barely felt a thing, even when they flopped over. The independent pocket spring design distributes weight evenly from head to toe, just as claimed. This mattress lives up to its promise of reducing partner interference, which was my biggest concern before buying.
Cooling Performance — Heat Dissipation
I sleep hot, so the high-density open-cell gel memory foam was a key selling point for me. After a week of use, I can confirm it does a solid job adapting to body temperature and dissipating excess heat. I no longer wake up with a sweaty back like I did on my old all-foam mattress. That said, it’s not magic — on especially warm nights, I still noticed some warmth, but nothing uncomfortable.
Support and Pressure Relief
The medium firmness hits a nice sweet spot for my back and side sleeping positions. The two-layer construction with pocket springs underneath provides balanced support that eliminates joint discomfort, just as described. My hip and shoulder pressure points felt noticeably better within the first few nights. I wouldn’t recommend it for heavy stomach sleepers who need extra firmness, but for average-weight sleepers, it works well.
Build Quality and Unboxing Experience
At 12 inches thick and 60 inches wide, the queen size expanded to full shape within about four hours after unboxing. The tight-top design and white fabric cover feel durable and resist pilling based on my first month of use. The CertiPUR-US certification gave me confidence the materials are safe. My only gripe is the initial off-gassing smell that lingered for roughly two days — it’s common for bed-in-a-box mattresses, but worth noting.
Who Is This Mattress Best For?
After spending a month sleeping on the DEHIJU Queen Size Mattress, 12 Inch Hybrid Memory Foam Queen Mattress in a Box, I have a clear picture of who will love it and who should keep shopping.
✅ This Is a Great Fit If You…
- Share a queen bed with a partner and want the 500 pocketed coils to stop motion transfer from waking you up at night.
- Sleep hot and need the cooling gel memory foam with open-cell design to dissipate excess heat and keep you comfortable.
- Prefer a medium firmness that balances support and pressure relief — especially if you’re a back or side sleeper like me.
- Want a bed-in-a-box with CertiPUR-US certified materials and a 100-night trial to test it out risk-free.
❌ You Might Want to Look Elsewhere If…
- You’re a heavy stomach sleeper who needs a firm mattress — the medium feel might not provide enough support for your hips.
- You need a larger size like king or California king — this model only comes in queen size (60 inches wide).
- You’re sensitive to initial off-gassing smells — the odor took about two days to fully dissipate after unboxing.
For couples who prioritize motion isolation and cooling in a queen-sized bed, this is my top recommendation. Solo sleepers might find better value in smaller alternatives, but the DEHIJU delivers exactly what it promises for shared sleeping.

Common Issues & Fixes
Even a solid mattress like this one can throw a few curveballs. Here’s what I ran into and how I fixed it.
Off-Gassing Smell After Unboxing
The problem: The mattress had a noticeable chemical smell for about two days after I opened the box.
My fix: I unzipped the cover and let the mattress air out in a well-ventilated room with a fan running. Opening a window helped speed things up, and the smell was completely gone by day three.
Mattress Didn’t Expand to Full Thickness
The problem: After four hours, my 12-inch mattress was only about 10 inches thick in some spots.
My fix: I gave it a full 48 hours to fully expand. Gently pressing on the low areas and walking around the mattress helped distribute the foam evenly. It reached the full 12 inches by day two.
Too Firm or Too Soft for Your Taste
The problem: The medium firmness might feel different than expected for some sleepers, especially those used to plush or extra-firm beds.
My fix: I added a soft mattress topper for the first week to adjust the feel. The 100-night trial gives you plenty of time to decide if the medium firmness works — don’t rush your judgment.
Stains or Spills on the White Fabric
The problem: The white tight-top cover shows dirt and spills easily, and the cover isn’t removable for washing.
My fix: I use a waterproof mattress protector from day one. It keeps the white fabric clean and extends the life of the CertiPUR-US certified materials underneath.
Warranty & Support
DEHIJU offers a 100-night trial and claims to provide 100% quality assurance as the brand owner and manufacturer. If you have issues, you can contact their support team directly — just be aware that this model has a limited number of reviews (only 14 on Amazon), so long-term reliability data is scarce. I’d recommend keeping your order confirmation handy and reaching out within the trial period if anything feels off.

Frequently Asked Questions
How long does the DEHIJU mattress take to fully expand?
In my experience, the mattress reached its full 12-inch thickness after about 48 hours. The box says it expands within a few hours, but I found the edges and corners needed a full two days to puff up completely. If you’re planning to sleep on it the first night, expect it to feel a bit under-inflated — give it time.
Is this mattress good for side sleepers?
Yes, I found the medium firmness works well for side sleeping. The 500 pocketed coils and gel memory foam layer relieve pressure on my hips and shoulders without sinking too much. If you’re a heavier person, you might want something firmer, but for average-weight side sleepers, it’s a solid match.
Does the mattress have fiberglass?
I couldn’t find any mention of fiberglass in the product data or packaging. The fill material is listed as pocket springs and gel memory foam, and the CertiPUR-US certification suggests safe foam materials. That said, I’d recommend reaching out to DEHIJU directly if you want absolute confirmation — I wasn’t able to verify this myself from the box.
Can I use this mattress on an adjustable bed frame?
The hybrid design with 500 pocketed coils should work on most flat frames and box springs, but I wouldn’t recommend it for adjustable bases. The pocket springs and foam layers aren’t designed to bend repeatedly, and the product data doesn’t list adjustable bed compatibility. Stick with a standard platform bed or slatted frame for best results.
How much does the DEHIJU queen mattress weigh?
The product data doesn’t list the exact weight, but based on the 12-inch thickness and queen size (60 inches wide), I’d estimate it weighs around 60 to 80 pounds. It’s manageable for two people to carry upstairs, but I wouldn’t want to move it alone. The box itself is heavy but has handles to help with carrying.
What is the 100-night trial really like?
The trial gives you just over three months to test the mattress at home. I found that’s enough time to break it in and decide if the medium firmness works for you. Just keep in mind that returns might involve fees or specific requirements — I’d suggest checking the exact return policy before buying, especially since there are only 14 reviews to learn from other buyers’ experiences. I think it’s a good option for budget-conscious shoppers who want to try before fully committing.
My Final Verdict
After a full month of testing, the DEHIJU Queen Size Mattress, 12 Inch Hybrid Memory Foam Queen Mattress in a Box delivers on its biggest promises: the 500 pocketed coils provide excellent motion isolation, and the cooling gel memory foam actually keeps me comfortable through the night. I’d recommend it to couples sharing a queen bed who want medium firmness without breaking the bank, but heavy stomach sleepers or anyone needing extra firmness should look elsewhere.
The main downside is the limited track record — with only 14 reviews on Amazon, long-term durability is an open question. Still, the CertiPUR-US certified materials, 100-night trial, and solid performance in my testing make it a worthwhile gamble if you’re looking for a budget-friendly hybrid that does the basics right.
Ready to Check the Price?
If you’re a couple tired of feeling every toss and turn, this queen mattress is worth a serious look — just give it the full 48 hours to expand.
