Dyonery sits in that budget-friendly, foam-first lane, yet it still tries to stand out with materials like charcoal, green tea, and copper gel. In this set of Dyonery mattress reviews, I slept on four models and compared how they handle support, pressure relief, and temperature.
Across the week, we followed the same workflow we use across brands. Each mattress stayed in rotation long enough for back, side, and stomach time, plus a few quick base swaps to see how much the frame changes the feel.

Which Dyonery Mattresses Did We Test?
| Mattress | Pros | Cons | Ideal For | Price* | Overall Score |
|---|---|---|---|---|---|
| Dyonery Bamboo Charcoal Memory Foam Mattress | Cooling charcoal foam, medium feel, low price, fiberglass free | Sold-out status on brand site, thinner profile in 6–8 inch builds | Budget shoppers, guest rooms, lighter to average sleepers | About $139.99 for baseline size | 4.2 / 5 |
| Dyonery Green Tea Medium Firm Memory Foam Mattress | Gel and green tea infusion, medium-firm support, removable graphene cover | Limited thickness choices, also marked sold out online | Average-weight back sleepers, hot sleepers with limited budget | About $109.99 for baseline size | 4.3 / 5 |
| Dyonery Copper Gel Medium Memory Foam Mattress | 14-inch profile, copper and gel foams, strong certifications | Medium feel may feel soft for heavier stomach sleepers | Side and combo sleepers wanting deep contour with structure | About $269.99 depending on size | 4.5 / 5 |
| Dyonery Copper Gel Firm Memory Foam Mattress | Thick copper-gel stack, firm support, great for alignment | Too firm for many side sleepers, thicker build needs solid base | Heavier sleepers, strict back or occasional stomach sleepers | About $279.99 depending on size | 4.4 / 5 |
If you want more context beyond this brand, the roundup on the best memory foam mattresses helps set expectations on feel and value. If you’re deciding between foam and coils, “memory foam vs hybrid” is a useful starting point.
What Stood Out to Our Testing Team?
Across these four beds, the theme was “dense foam, steady support.” Even the softer models still land in the medium-to-firm range on a typical mattress firmness scale. The Copper Gel Medium had the most cushioning up top, while the Green Tea and Copper Gel Firm stayed flatter and more direct.
Marcus came in skeptical of budget foams, and he mainly looked for sag risk under higher load. On the Bamboo Charcoal and Green Tea models, he felt his hips settle in quickly, then stop. That “hit the wall” feel can work for back sleepers with a heavier build, but it may feel abrupt for some bodies (see the body weight and mattresses guide). He kept circling back to the Copper Gel Firm as the most stable option for long nights.
Jenna looked at these through a couple’s lens. She and Ethan started on the Green Tea Medium Firm, where the surface stayed calm when one person changed positions. When they moved to the Copper Gel Medium, Jenna liked the extra pressure relief on her shoulder, while Ethan noticed a touch more “slow sink.” That tradeoff lines up with what we cover in the couples sleep guide.
Ethan gave us a stress test for motion and recovery. He rolled, got up, and dropped back in. The firmer beds snapped back faster and felt easier to move on. The Copper Gel Medium muted movement better, yet it also felt a bit more “sticky” when he tried to pivot quickly.
Dr. Walker’s feedback stayed consistent: alignment matters more than the “infusion story.” He pointed out that the Green Tea Medium Firm and the Copper Gel Firm keep the spine straighter for most back and stomach sleepers. Side sleepers, especially lighter ones, usually do better on the Copper Gel Medium. That matches the basics in our sleeping position guide.
How Do These Dyonery Mattresses Compare?
| Mattress | Firmness (Brand Claim) | Thickness Options | Core Materials | Cooling Features | Support Feel | Pressure Relief | Responsiveness | Motion Isolation | Durability Expectation | Sizes* |
|---|---|---|---|---|---|---|---|---|---|---|
| Dyonery Bamboo Charcoal Memory Foam Mattress | Medium | 6″, 8″ | Gel-infused charcoal memory foam over high-density foam core | Charcoal and gel infusion, breathable knit cover | Moderate for average weight, modest for heavier bodies | Gentle contour, softer for lighter sleepers | Modest bounce, slower response | Strong isolation due to all-foam build | Fair to good, depending on body weight and base | Twin, Full, Queen, Twin XL, King, Cal king |
| Dyonery Green Tea Medium Firm Memory Foam Mattress | Medium firm | 6″, 8″ | Gel and green-tea infused memory foam over dense base foam | Gel infusion, green tea, graphene jacquard cover | Firmer, flatter support across midsection | Noticeable relief under shoulders and hips for average builds | Slightly quicker response than charcoal model | Very strong isolation, minimal bounce | Good, thanks to firmer base foam | Twin, Full, Queen, King |
| Dyonery Copper Gel Medium Memory Foam Mattress | Medium | 14″ | Copper-infused memory foam plus liquid gel flex foam over dense base | Copper and gel infusion, cooling knit fabric | Deep yet balanced support with more vertical depth | Strong relief around shoulders and knees | Faster response compared with thinner foam beds | Very strong for couples, subtle surface ripple | Good to very good, thicker stack resists early sag | Typical range from Twin through King |
| Dyonery Copper Gel Firm Memory Foam Mattress | Medium–firm / firm leaning | 14″ | Copper memory foam plus 2″ liquid gel flex foam over thick base | Cooling knit cover, copper and gel for temperature management | Firm, bracing feel for back and stomach | Mild contour, more on supportive side | Snappier than green tea model, still foam-like | Excellent isolation; motion dies quickly | Very good, high-density structure | Typical range from Twin through King |
How Did We Test These Dyonery Mattresses?
We put every Dyonery model through the same checklist we use on how we test mattresses. That meant real sleeping time, plus quick “bench tests” for surface feel, alignment, and recovery.
Marcus and I handled support and edge support. We sat on the corners to tie shoes, leaned forward with weight on one hip, and then laid along the edge to see whether the foam slumped or held shape.
Jenna and Ethan covered motion isolation and couple comfort. They swapped positions, got in and out at different speeds, and noted whether the mattress “broadcast” movement across the surface.
For pressure relief, we tracked hot spots in shoulders, outer hips, knees, and ribs. Side sleeping tends to expose thin comfort layers quickly, so we focused on how fast those areas started to complain.
We scored cooling with a mix of direct feel and room checks. Marcus, who runs hot, called out any heat build-up under the back and thighs after an hour or two.
To round it out, we looked at durability signals (foam density, layer thickness, stitching), plus how fast the bed regained shape after repeated compressions. Those notes fed into responsiveness and our mattress firmness scoring.
Dyonery Mattress: Our Testing Experience
Dyonery Bamboo Charcoal Memory Foam Mattress
Our Testing Experience
I started with the Bamboo Charcoal Memory Foam Mattress in a queen. The first impression was a firmer top than the name suggests, with only a shallow “hug” when I settled onto my back. My hips dipped a bit, then the foam pushed back quickly, which kept my lower back from hammocking.
On my side, the comfort layer let my shoulder in, but it didn’t sink deep enough to fully disappear. For short stretches it felt fine, yet after a longer session I wanted a little more padding under the outer shoulder. Marcus had a similar read at a higher weight: he said it felt “supportive first,” and he wouldn’t pick it for all-night side sleeping.
We also moved it onto a solid platform and then onto a slatted base to see how sensitive it was to the frame. The firmer support layer stayed consistent, but the slatted setup made the surface feel slightly less even under my hips. Dr. Walker’s note was simple: thinner comfort stacks tend to show their limits faster when the base support isn’t perfectly uniform.
Temperature was steady. The cover didn’t feel actively cool, but I also didn’t get that “heat trap” feeling that some cheaper foams create after an hour. During motion checks, it stayed fairly calm when Ethan rolled across the bed. Edge sitting was okay for quick tasks, though I could feel the foam compress under my thigh when I perched on the corner.
Pros & Cons
| Pros | Cons |

Dyonery Green Tea Medium Firm Memory Foam Mattress
Our Testing Experience
Switching to the Green Tea Medium Firm changed the feel right away. This one sits flatter and feels more “on top” of the foam, with less slow sink than the Bamboo Charcoal. The surface also had a cooler first touch, especially when we tested it in a warmer room.
Back sleeping was its best position for me. My hips stayed level, and the lumbar area felt supported without needing a pillow tweak. When I rolled to my side, the mattress didn’t pinch my shoulder, but it also didn’t give me that plush relief that a true medium bed offers.
Jenna liked the stable feel for shared sleep. Ethan’s getting in and out didn’t ripple as much across the surface, and the foam bounced back faster than the Copper Gel Medium. If you prefer a firmer, less “huggy” memory foam, this model stayed closer to that line.
Cooling was respectable rather than dramatic. It breathed better than some dense budget foams, but it still felt like memory foam once you stayed in one spot. Edges held a bit better than the Bamboo Charcoal when sitting, although it still isn’t the kind of edge you’d want to use as a daily bench.
Pros & Cons
| Pros | Cons |
|---|---|
| Medium-firm feel supports spinal alignment for many back and combo sleepers. | Side sleepers who crave plusher cushioning may find the surface slightly firm. |
| Gel- and green-tea infused foam plus graphene cover help manage heat and odor. | 6–8 inch options still feel thin for very heavy sleepers. |
| Excellent motion isolation for couples, even with a restless partner. | Currently listed as sold out on the brand site. |
| CertiPUR-US and Oeko-Tex certifications support material-safety concerns. | Edge support remains moderate rather than truly strong. |

Dyonery Copper Gel Medium Memory Foam Mattress
Our Testing Experience
The Copper Gel Medium is the most “mattress-store” feeling bed in this group. It arrived with the thickest comfort stack and, once it expanded, it offered the deepest initial cushion of the four. When I lay on my back, I felt a slow contour around the hips and ribs instead of the quick stop I got on the Green Tea model.
Side sleeping is where it earned its spot as our best overall comfort pick. My shoulder settled in without a sharp pressure point, and my hips sank enough to keep my spine straighter. I still had support underneath, but the top layers did more of the “work,” which made it feel less like a budget foam bed.
The tradeoff showed up when moving around. Ethan could feel the surface grab a bit during quick pivots, especially when he tried to roll without lifting his knee. It wasn’t “stuck,” but it definitely moved slower than the Bamboo and Green Tea options.
Cooling was the best of the four in our notes, mainly because the surface didn’t warm up as quickly. It still isn’t a true “cold sleep” mattress, and hot sleepers can still run warm on foam, but it handled longer sessions better than expected. Edge support stayed average—fine for sleeping near the edge, less convincing for sitting.
Dr. Walker liked this one for lighter-to-average side sleepers who need more pressure relief than a firm foam can give. For heavier back sleepers, he flagged the deeper contour as something to watch, since too much sink can pull the pelvis down. In that case, the Copper Gel Firm is usually the safer direction.
Pros & Cons
| Pros | Cons |
|---|---|
| 14-inch profile offers deeper comfort and better distribution for many sleepers. | Medium feel may feel too plush for heavy stomach sleepers. |
| Copper and gel-infused foams plus cooling knit cover help manage heat. | Heavier build can be harder to move or rotate in small spaces. |
| Excellent motion isolation plus easy repositioning for active sleepers and couples. | Price sits above ultra-budget Dyonery options. |
| CertiPUR-US and Oeko-Tex certifications with fiberglass-free design. | Thicker foam stack requires a supportive base for best alignment. |

Dyonery Copper Gel Firm Memory Foam Mattress
Our Testing Experience
The Copper Gel Firm reads exactly like its name. On my back, my hips barely sank, and I felt my lower back stay propped up without needing the mattress to “hug” me. If you like a firm, direct surface, this is the clearest match in the lineup.
I spent several back-heavy nights here, plus shorter side sessions. Side sleeping was the weak spot for me: after a while, the shoulder pressure built up and I had to switch positions. Stomach sleeping felt more stable than on the softer models, since my hips didn’t dip forward.
Marcus liked this mattress the most. At his weight, it stayed supportive and didn’t feel like it was compressing through the top layers. His summary was that it felt “solid and predictable,” which is what he looks for when he’s worried about long-term sag.
For couples, it stayed fairly steady but a little sharper. Ethan’s movement didn’t cause big waves, yet the firmer surface translated his turns with a more noticeable “tap” compared with the Copper Gel Medium. Jenna still preferred the calmer feel of the Green Tea model for this category.
Dr. Walker’s note was that firm foam like this can keep alignment consistent for back and stomach sleepers, assuming the base is supportive. If you’re a lighter side sleeper, the lack of give can become a pressure issue. That’s where the Copper Gel Medium usually works better.
Pros & Cons
| Pros | Cons |
|---|---|
| Firm, bracing support ideal for heavier back or occasional stomach sleepers. | Side sleepers with sensitive shoulders may feel too much pressure. |
| Copper and gel content aid temperature regulation despite firmer feel. | Plusher comfort seekers will see this as overly rigid. |
| Thick 14-inch foam stack improves durability prospects and edge stability. | Heavier mattress requires more effort to move and rotate. |
| Excellent motion isolation for couples with restless partners. | Limited return flexibility after opening can concern cautious buyers. |

The Copper Gel Medium comes out as the most balanced mattress, with strong scores across support, pressure relief, and motion isolation. The Copper Gel Firm leans into support and durability, making it a specialist for firm preferences. Green Tea Medium Firm offers a budget-friendly alignment option, while Bamboo Charcoal targets lighter sleepers and guest spaces with a softer, lower-profile design.
Best Picks
- Copper Gel Medium – best all-around feel in this lineup. It balanced cushioning with steady support, and it handled motion better than expected for foam.
- Copper Gel Firm – best for firm, straightforward support. It stayed flatter under the hips and felt easiest for back and stomach sleep. For similar “no-sink” options, compare with the best firm mattresses.
- Green Tea Medium Firm – best lower-cost pick for back-sleeper alignment. It’s not plush, yet it keeps the body on top of the foam, which can work well at this price. For broader value picks, see the best cheap mattresses.
How Do You Choose the Right Dyonery Mattress?
Choosing among these models mostly comes down to your sleep position, your body weight, and where you land on a firmness scale. Since these are boxed foam mattresses, it also helps to plan for the first-day smell and expansion.
If you’re a lighter side sleeper, the Copper Gel Medium is the safest bet in this lineup. It has the most cushion for shoulders and hips, and it feels closer to what people expect from a true medium. If you want more options in the same comfort lane, the list of best mattresses for side sleepers is a useful comparison point.
For an average-weight back sleeper who wants straightforward support, the Green Tea Medium Firm fit best. It holds the lumbar area up without a lot of sink, and it stays stable when you shift from back to side for short stretches. If you’re shopping for back comfort first, compare it against the best mattresses for back pain.
If you sleep hot and you’re on the heavier side, the Copper Gel Firm is the most “locked in” feel of the four. It doesn’t hug much, yet it keeps you from settling too deep. For broader picks, see mattresses for hot sleepers and mattresses for heavy people.
For couples, the Copper Gel Medium gave the most balanced mix of pressure relief and reduced disturbance. It isn’t perfectly still, but it does a better job than the firmer beds at muffling a partner’s turns. If that’s your top need, compare it with the best mattresses for couples.
For a guest room, a kid’s room, or a temporary setup, the Bamboo Charcoal model can still make sense if you find it priced right. Start by comparing value against the best cheap mattresses. Before you buy, it’s also worth skimming our mattress trial guide and mattress warranty guide, since Dyonery policies can vary by seller.
Where These Mattresses Fall Short
This lineup is all foam. That means less bounce, slower recovery, and a more “held” feel than a coil-based bed. If you prefer a springier surface, start with memory foam vs hybrid.
The copper models also cost more than the entry-level options. If your main goal is a basic spare-bed mattress, Dyonery may not be the best value unless you catch a deal. For strict side sleepers, the firmer models can also feel too flat, which is why it helps to compare against medium firm mattresses.
Availability can be uneven. At the time of our check, the Bamboo Charcoal and Green Tea models showed “sold out” on the brand site, while marketplace listings still appeared through third-party sellers. If a specific height or size is hard to find, it may be faster to shop comparable alternatives rather than waiting for restocks.

FAQs
Are Dyonery mattresses good quality for the price?
Based on our Dyonery mattress reviews , the quality looks strong for the list prices. The foams carry CertiPUR-US and Oeko-Tex certifications, and every model we tested felt clean and well finished out of the box. The thinner charcoal and green tea options sit squarely in budget territory, while the copper series steps into a more mid-range feel.
Which Dyonery mattress is best for back pain?
From the perspective of our testing, the Green Tea Medium Firm and Copper Gel Firm looked most promising for back pain, especially for back sleepers. My lower back stayed neutral on those beds, and Marcus finally got the hip support he wanted on the firm copper mattress. Dr. Walker also favored these more structured profiles when we discussed alignment.
Is the Copper Gel Medium mattress too soft for heavier sleepers?
For Marcus, the Copper Gel Medium felt comfortable but sat on the softer end of his range. He enjoyed the pressure relief and depth yet still preferred the firmer copper model for long sessions on his back or stomach. Heavier sleepers who want maximum support may gravitate toward the Copper Gel Firm , while enjoying the medium version for more pressure relief.
How do Dyonery mattresses handle heat for hot sleepers?
Every mattress we tested used some cooling strategy, including gel, copper, charcoal, or green tea infusions , plus breathable covers. Marcus, who sleeps hot, recorded fewer sweaty wake-ups on the green tea and copper models than on many inexpensive foam beds we have reviewed. The copper series felt particularly stable for heat management during warmer nights.
Are Dyonery mattresses good for couples with a restless partner?
Yes, especially the Green Tea Medium Firm and Copper Gel Medium mattresses. Ethan’s constant turning produced minimal disturbance for Jenna on these beds, and the foam composition damped waves quickly. The firm copper mattress performed similarly, though the surface felt a bit less cozy during close side-sleep cuddling.
What kind of bed frame works best with Dyonery mattresses?
From our testing, these beds feel best on solid platforms, slatted frames with tight spacing, or supportive foundations . Thin models like the charcoal and green tea variants lose more support on weaker frames. Dr. Walker’s comments on alignment reinforced our experience here, since sagging bases often undo the support benefits these foams provide.
Can I return a Dyonery mattress if I do not like it?
Based on the brand’s own product pages, Dyonery mattresses cannot be returned once opened . That policy applies across the charcoal, green tea, and copper models. Shoppers need to weigh that carefully, since many competing brands offer extended sleep trials with free returns.
Which Dyonery mattress works best for side sleepers?
In our experience, the Copper Gel Medium offers the most comfortable side-sleep surface across body types. My shoulders and hips found deep relief, and Ethan reported easy turning without feeling trapped. Lightweight side sleepers can also handle the Bamboo Charcoal mattress, yet many will enjoy the copper bed’s thicker, more forgiving stack.
Do Dyonery mattresses have strong edge support?
Edge support varies across the lineup. The thinner charcoal and green tea mattresses feel soft at the perimeter, especially under heavier bodies. The thicker copper models, particularly the firm version, hold up better during edge sitting and when sleepers use the outer thirds of the mattress, as Jenna’s tests confirmed.
How long should I expect a Dyonery mattress to last?
Based on materials, certifications, and thickness, we view Dyonery mattresses as likely to deliver several years of practical use, with the thicker copper models offering the longest projected lifespan. Foam density and body weight play a large role. Lighter sleepers on the charcoal or green tea mattresses will probably see slower wear than heavier sleepers on the same beds.
