The difference between an all natural mattress and a conventional one isn’t subtle once you know what’s inside — petrochemical polyfoams, chemical flame retardants, and synthetic latex blends are standard in most bed-in-a-box models, and your body absorbs that chemistry for eight hours every night. An all natural mattress replaces every one of those ingredients with materials that are grown, not manufactured: organic cotton, organic wool, and natural latex from rubber trees, with steel coils as the only synthetic component.
I’m Mo Maruf — the founder and writer behind The Tools Trunk. I’ve spent hundreds of hours analyzing material certifications, layer constructions, and real-world durability data across the all-natural mattress category to separate marketing claims from genuinely non-toxic builds.
This guide breaks down twelve models that actually qualify as all-natural, from latex-only builds to hybrid designs with pocketed coils, pulling apart the GOLS and GOTS certifications, the wool batting density, and the latex ILD ratings that determine whether a mattress will support your sleep style without off-gassing or early sagging. This is the definitive resource for finding the right all natural mattress for your specific needs.
How To Choose The Best All Natural Mattress
Picking an all-natural mattress is less about brand names and more about reading the ingredient list — because unregulated terms like “natural” and “eco-friendly” hide a lot of polyurethane in the fine print. The three certifications that actually matter are GOLS (for latex), GOTS (for cotton and wool), and Greenguard Gold (for low VOC emissions across the whole mattress).
Latex Type and ILD Rating
Natural latex comes from rubber tree sap, but many mattresses labeled “natural” use a blend of natural and synthetic latex (SBR) to cut cost. Only GOLS-certified latex guarantees 95% or higher natural content. The ILD number tells you the firmness: 19-24 ILD is plush, 24-30 ILD is medium, and 30+ ILD is firm. Side sleepers generally need lower ILD for pressure relief, while stomach and back sleepers need higher ILD for spinal alignment.
Wool as a Fire Barrier
The federal flammability standard (16 CFR 1633) requires all mattresses to resist open-flame ignition. Most manufacturers meet this with chemical flame retardants or fiberglass. All-natural mattresses use organic wool batting, which is naturally fire-resistant because wool fibers have high nitrogen and moisture content — they smolder rather than ignite. The wool layer should be at least 1 inch thick and GOTS-certified to confirm it’s free of chemical scouring treatments.
Coil Construction vs. All-Latex
All-latex mattresses (8-9 inches of solid latex) offer the purest natural construction and the longest lifespan — latex doesn’t sag like polyfoam — but they’re heavy and have a distinct bouncy feel. Hybrid builds with pocketed coils and a latex comfort layer feel more similar to conventional mattresses and breathe better due to the open coil structure, but the coils themselves are steel (not natural) and the mattress will eventually wear out from coil fatigue. Your choice depends on whether material purity or familiar feel matters more.

In‑Depth Reviews
1. Pure Green Organic Latex Mattress – Medium Firmness – Queen
The Pure Green from Sleep On Latex is the benchmark for pure all-latex construction at a mid-range price — no blended latex, no polyfoam, no fiberglass. The 8.5-inch slab of GOLS-certified natural latex comes in medium firmness with an ILD around 24-26, making it suitable for side sleepers who need pressure relief and back sleepers who want spinal support without sinking. The cover is organic cotton quilted with organic wool batting, and the mattress is compressed in paper rather than plastic, which cuts down on packaging waste and eliminates the chemical smell that plastic shrink-wrapping often leaves behind.
Customer feedback consistently describes the medium firmness as having a gently supportive surface that feels responsive rather than dead — latex bounces back instantly, so you don’t get that “stuck in the foam” sensation. Heavier side sleepers (over 200 lbs) report that a 2-inch soft latex topper turns the mattress into an ideal plush-support combo, while lighter users find the medium ILD comfortable right out of the box. The mattress expands in about an hour, and the earthy latex smell dissipates within a day or two.
One caveat: at 8.5 inches thick, this mattress sits lower than the 10-13 inch models common in the hybrid category, so standard sheet sets with deep pockets may require extra tightening clips. The mattress is also very heavy — roughly 125 pounds for a queen — and lacks handles, so plan for two people during setup. Sleep On Latex offers a 100-night trial and a 20-year warranty, which is competitive for a latex mattress at this price point.
What works
- 100% GOLS-certified natural latex with no synthetic rubber
- Organic cotton and wool cover with no chemical fire retardants
- Expands quickly and off-gasses very little compared to polyfoam
What doesn’t
- 8.5 inch height may not fit deep-pocket fitted sheets properly
- Very heavy and difficult to move without handles
2. Ethical Mattress CO 10″ Toxin-Free Hybrid Mattress Queen
The Ethical Mattress Co 10-inch hybrid is one of the most rigorously toxin-free builds on the market — it contains absolutely no polyurethane foams, no fiberglass, no chemical flame retardants, and the updated design removes even the rayon-poly blend that earlier versions used. The construction is pure organic cotton stretch-knit cover, organic wool batting as a fire barrier, a top layer of GOLS-certified organic latex, and a base of individually pocketed steel coils with no foam encasement around the perimeter, which allows air to flow freely through the entire mattress core.
Owner reviews consistently highlight the medium firm feel (roughly 7 out of 10) as a perfect balance for combination sleepers, with the latex comfort layer providing enough give for side sleeping while the coil base keeps the spine aligned for back sleepers. The wool layer regulates temperature effectively — multiple users mention sleeping cooler than on memory foam hybrids. The queen weighs 88 pounds, which is noticeably heavier than comparable hybrids, and the company explicitly states that weight is an indicator of material density and quality.
The main concern from long-term users is that the mattress may feel too firm for chronic pain sufferers or lightweight side sleepers without a plush topper, and one review noted a persistent smell that lasted beyond a week, though the majority report zero off-gassing. The company recommends calling before purchase to confirm firmness selection and reduce the risk of returns. Made in New Jersey with a 120-night trial.
What works
- Absolute zero polyfoam construction — only cotton, wool, latex, and steel
- Excellent breathability due to no foam coil encasement
- Customer service is responsive and helps with firmness matching
What doesn’t
- Firm 7/10 feel may be too stiff for lightweight side sleepers
- Weight makes repositioning and setup difficult
3. Happsy Organic Hybrid Mattress Queen
Happsy’s organic hybrid mattress is GOTS-certified across the entire mattress (not just the cover) and holds Greenguard Gold certification for low VOC emissions, which is the highest indoor air quality standard for sleeping products. The build uses an organic cotton and wool cover, a layer of organic latex for pressure relief, and an encased steel coil innerspring with no glue — the layers are held together by the wool’s natural friction and the coil tension alone, which eliminates adhesive off-gassing.
Long-term owners consistently report that the mattress holds its shape without sagging even after multiple years of use, which is a strong indicator of the latex and coil quality. The firm feel is recommended for stomach and back sleepers who need consistent support, and the wool layer provides natural moisture wicking that keeps the surface dry and temperature neutral. One reviewer noted their king mattress measured over 11 inches after expansion, slightly taller than the listed 10 inches, but the comfort and non-toxic construction were described as excellent.
The biggest complaint is the weight — a king size weighs around 126 pounds and the mattress arrives rolled in a tall box that requires two people to maneuver. A few owners mention that the firm support is less forgiving for side sleepers, and using a separate organic wool topper helps achieve a softer feel without introducing synthetic materials. Happsy is made in the USA and comes with a 20-year warranty and 120-night trial.
What works
- Full GOTS and Greenguard Gold certification across all materials
- Glueless assembly eliminates adhesive off-gassing in the mattress
- Proven durability with no sagging after years of regular use
What doesn’t
- Firm feel is less comfortable for side sleepers without a topper
- Extremely heavy and awkward to move during setup
4. COTTON SLEEP All Natural 11″ Mattress King
Cotton Sleep’s 11-inch hybrid uses a 100% organic cotton cover (no synthetic blends hidden in the thread count), temperature-regulating New Zealand wool, and responsive certified organic latex over a pocketed coil base. The “Adaptive Core” coil array is strategically zoned to provide firmer support in the lumbar region while allowing more give in the shoulder and hip zones, which improves spinal alignment for side sleepers and reduces pressure points.
Customer feedback highlights the medium firmness as a near-universal comfort level — firm enough for stomach sleeping but with enough latex flex to avoid shoulder stiffness. The cooling performance gets strong marks: the cotton and wool combination wicks moisture effectively, and the open coil base prevents heat from getting trapped in the mattress core. Several reviewers mention that after trying multiple organic mattresses (returning others), this model was the one that delivered both comfort and temperature neutrality without any chemical smell.
The mattress is made in the USA and ships rolled in a compact box. One owner noted a slight warp on the top edge from the shrink wrapping, but this corrected after a few days of expansion. The mattress supports up to 900 pounds and carries a 120-night trial period.
What works
- 100% organic cotton cover with no blended synthetics in the fabric
- Zoned pocketed coil array improves lumbar support for side sleepers
- Breathable wool and latex layers prevent heat retention effectively
What doesn’t
- Initial shrink wrap may leave temporary edge impressions during expansion
- Heavy king size weight requires two people for handling
5. Pure Green Organic Latex Mattress – Firm – Twin XL
This is the firm version of Sleep On Latex’s GOLS-certified all-latex mattress, with an ILD rating of approximately 34-38 that delivers a very supportive, near-solid surface with just enough flex to relieve pressure points. The 8.5-inch depth is filled entirely with natural latex — no foam layers, no coils, no polyurethane — and the organic cotton cover is quilted with organic wool for a naturally fire-resistant build. The mattress ships compressed in paper, not plastic, and expands to full shape within minutes after unwrapping.
Twin XL owners consistently describe the mattress as extremely firm, ideal for heavier individuals (240+ lbs) who need deep support without bottoming out, and for stomach sleepers who require a flat surface to prevent hip sink. One 6’2″ reviewer weighing 240 lbs reported that the firmness eliminated morning back stiffness, while their 110 lb partner found it uncomfortable and required a soft latex topper. The mattress works well on adjustable bases, and the latex material allows the frame to flex without creating stress points in the mattress.
The main consideration is that this firmness is not forgiving for lightweight side sleepers or anyone with arthritis — multiple reviewers recommend pairing it with a 2-inch soft latex topper (available from the same company at a discount if you call) to create a 9/10 firmness combination that supports weight distribution while adding plushness. The latex is bouncy and responsive, sleeps cooler than memory foam, and has minimal motion transfer.
What works
- Extremely firm support for heavy individuals and stomach sleepers
- 100% natural latex with GOLS certification — zero synthetic fillers
- Expands rapidly with minimal off-gassing and no plastic wrap
What doesn’t
- Too firm for lightweight side sleepers without a soft topper
- Heavy and lacks handles, making solo setup challenging
6. Eco Terra Natural Latex Luxury Hybrid Mattress Queen
Eco Terra’s luxury hybrid uses a single seamless 3-inch layer of 100% natural latex from Arpico (a GOLS-certified Sri Lankan grower) over Quantum edge-coil encased springs, delivering a medium firm feel with an ILD of 29-31 on the firmer side of the medium spectrum. The latex layer is solid, not blended or synthetic, and the coils are individually wrapped with a thicker gauge around the perimeter to reduce edge roll-off and improve sitting support.
Reviews for this model are split along firmness expectations — users who prefer a truly medium feel find the mattress supportive and well-balanced for chronic back pain, while those expecting a plush surface describe the medium-firm as extremely hard and unusable without a topper. This ILD range is firmly in the medium-firm category, so it translates to a 7-8 out of 10 firmness, which is better suited for back and stomach sleepers than side sleepers who need softer pressure relief.
A more significant concern is longevity — a small but notable set of reviews report significant sagging developing within 12-18 months, leading to back pain recurrence. This suggests the latex layer or coil quality may vary between units. The GOTS-certified organic wool and cotton cover are well-constructed, and the edge support is genuinely improved by the Quantum coil design, but the early sagging reports are worth weighing against the price point. Eco Terra offers a 30-day return window through Amazon.
What works
- Single-source GOLS-certified Arpico latex with consistent ILD grading
- Reinforced perimeter coils provide stable edge support for sitting
- Organic cotton and wool cover is breathable and well-finished
What doesn’t
- Multiple reports of premature sagging within the first 12-18 months
- 30-day return window through Amazon is shorter than category standard
7. Helix Midnight Luxe Mattress Queen
The Helix Midnight Luxe is a premium hybrid designed specifically for side sleepers, featuring up to 1,000 individually wrapped steel coils with targeted zoned lumbar support that provides firmer pushback in the lower back area while allowing softer conforming around the shoulders and hips. The 13.5-inch profile includes a TENCEL quilted pillow top for moisture wicking and breathability, and the mattress is GREENGUARD Gold certified and uses CertiPUR-US certified foams with no fiberglass.
Side sleepers consistently report that the Midnight Luxe eases hip pain and reduces the need to adjust positions during the night, with the zoned coil system feeling noticeably supportive in the lower back without creating pressure points. The medium firmness (6 out of 10) is softer than most all-natural builds, which works well for lighter sleepers who find latex too firm. TENCEL fabric is plant-based and more sustainable than polyester blends, but the comfort foam layers are not all-natural — they’re CertiPUR-US certified polyurethane, not latex or wool.
The primary limitation for the all-natural buyer is that this mattress uses polyfoam in its pressure-relieving layers, even though it avoids fiberglass and chemical flame retardants. One lightweight side sleeper at 155 lbs found the lumbar support too aggressive and the mattress runs warm compared to wool-latex hybrids. Helix offers a 120-night sleep trial and limited lifetime warranty.
What works
- Zoned coil system provides targeted lumbar pressure relief for side sleepers
- TENCEL pillow top is moisture-wicking and cooler than polyester
- 120-night trial with limited lifetime warranty
What doesn’t
- Comfort foam layers are polyurethane-based, not all-natural
- Some lightweight users find the lumbar zone too firm for side sleeping
8. Nectar Hybrid Full Mattress 12 Inch
The Nectar Hybrid combines CertiPUR-US certified gel memory foam with individually wrapped innerspring coils to create a medium firm feel (6.5 out of 10) at a price point considerably lower than all-latex builds. The memory foam layer is infused with cooling gel to counteract the heat retention typical of traditional memory foam, and the coil perimeter is reinforced with thicker-gauge wire to improve edge support and reduce roll-off. Nectar’s 365-night trial and forever warranty are the longest in the industry, which reduces the risk of trying a hybrid if you’re coming from a pure natural mattress.
Owner feedback is mixed over the long term. Short- and medium-term users (1-5 months) report improved back pain, good body contouring, and a balanced feel that works for couples with different sleep positions. However, a significant subset of owners report visible sagging and support degradation within 2 years, resulting in a raised center and uneven surface that reduces sleep quality. This pattern points to limited foam density or coil fatigue over time.
For the all-natural buyer, the key tradeoff is material purity: Nectar uses polyurethane foam with CertiPUR-US certification (no heavy metals or formaldehyde), but this is not a natural latex or wool construction. The mattress is fiberglass-free and made without ozone depleters, mercury, or phthalates. If you’re prioritizing material transparency and long-term durability over budget, the build quality difference between this and the GOLS-certified options is significant.
What works
- Industry-leading 365-night trial and forever warranty provide low-risk entry
- Cooling gel memory foam reduces heat retention compared to standard foam
- Medium firm feel suits a wide range of sleep positions and body types
What doesn’t
- Notable sagging and support loss reported within 2 years for some users
- Memory foam construction is not all-natural — contains polyurethane
9. DreamCloud Premier 13″ Queen Mattress
The DreamCloud Premier uses a 5-layer construction with a CloudQuilt quilted cashmere-blend cover, cooling fiber technology, and 2 inches of pressure-relieving memory foam over a high-density foam support core. The cashmere cover is more breathable than standard polyester, and the mattress is fiberglass-free and CertiPUR-US certified, with no ozone depleters, mercury, lead, or formaldehyde.
Short-term owners consistently report the mattress as extremely comfortable, with easy setup and noticeable back pain relief after the first night. The medium firm feel is designed to be universally accommodating, and the 8-person weight capacity (up to 800 pounds) suggests the foam density is substantial. The cashmere blend cover adds a soft hand feel that distinguishes it from basic polyester covers.
The limitation for this category is that DreamCloud is not an all-natural mattress — the memory foam is polyurethane-based, there is no natural latex or wool in the comfort layers, and the cover cashmere blend includes synthetic fibers. One report noted that the mattress was not supportive enough for back pain sufferers and had to be returned. The 365-night trial is generous, but the material composition doesn’t meet the all-natural standard.
What works
- Cashmere blend cover is softer and more breathable than standard polyester
- 365-night trial reduces buyer risk for unfamiliar hybrid specifications
- High 800 pound weight capacity indicates dense foam support layer
What doesn’t
- Memory foam construction is not all-natural — contains polyurethane foams
- Some back pain sufferers find the support lacking compared to latex
10. Ethical Mattress CO 10″ Toxin-Free Hybrid King
This is the king-size version of the Ethical Mattress Co hybrid, identical in construction to the queen reviewed earlier — organic cotton stretch-knit cover, organic wool fire barrier, GOLS-certified organic latex comfort layer, and no-foam encasement pocketed coils. The king weighs 107 pounds, which is 15% heavier than comparable hybrids from leading competitors, and the company uses this weight as a proxy for material density and durability.
King owners report the same medium firm (7/10) feel as the queen, with the coil array providing excellent motion isolation for couples. Multiple reviews highlight the absence of off-gassing, with even users sensitive to chemical smells reporting no odor upon unboxing. The mattress works on adjustable bases and inflates quickly from its compact ship box. The wool layer effectively regulates temperature, and the cotton cover is naturally moisture-wicking.
The same considerations apply as the queen version: the firmness is too stiff for lightweight side sleepers without a topper, and the 107-pound weight requires careful planning for delivery and setup. One review noted a persistent smell that did not fully dissipate after a week, although this is not the majority experience. Ethical Mattress Co recommends calling their customer service to discuss firmness preference to avoid restocking fees on the larger king format.
What works
- Complete zero polyfoam build with GOLS latex and pocketed coils
- Excellent motion isolation for couples sharing a king size bed
- No chemical off-gassing reported by the majority of users
What doesn’t
- 107 pound king size is extremely heavy and difficult to reposition
- Firmness may require a topper for lightweight side sleepers
11. Happsy Organic Hybrid Mattress King
The Happsy king is structurally the same as the queen but scaled up, weighing 126 pounds and maintaining the same firm medium feel from the organic latex comfort layer over glue-less encased coils. The GOTS certification covers the entire mattress, and the Greenguard Gold certification confirms ultra-low VOC emissions, making this one of the most thoroughly certified non-toxic hybrid mattresses in the king size category.
Long-term owners consistently praise the Happsy king for maintaining its shape and support level well past the point where polyfoam hybrids typically begin to sag. Several reviews reference 2-7 years of ownership with no structural degradation, which is significantly better than the 12-18 month sagging reports seen in some competitors. The organic wool batting provides natural temperature regulation, and the organic cotton cover is comfortable against the skin without needing additional sheets.
The firm feel is the same consideration as the queen — it’s designed for back and stomach sleepers, with side sleepers likely needing a separate topper. The 126-pound weight makes it the heaviest mattress on this list, and the king box is very tall when rolled, requiring careful navigation through doorways. Happsy offers a 120-night trial and 20-year warranty.
What works
- Proven long-term durability with no sagging after multiple years of use
- Full GOTS and Greenguard Gold certification across the entire mattress
- Glueless coil construction removes adhesive VOCs from the mattress core
What doesn’t
- Firm support is less comfortable for side sleepers without a plush topper
- 126-pound king size is extremely heavy and difficult to set up
12. Strobel Organic Keene HS2100dw Waterbed King
The Strobel Organic Keene is a complete waterbed system with a patented double-wall leak-proof Hydro-Support 2100 Feathertop water mattress that uses 13 layers of fiber (9 for full body support and 4 for lumbar support) to achieve near-waveless performance. The system includes a wood frame upholstered in black faux leather, a safety liner, a solid state water heater with thermostat control, a deck, pedestal, and a fill and drain kit with conditioner. The total height is 20 inches, and the heated water system keeps you warm in winter and cool in summer via convection.
Waterbed owners consistently report better sleep quality, with deeper sleep and longer duration compared to foam or hybrid mattresses. The waveless fiber layers significantly reduce the traditional waterbed wave motion, and the temperature control allows for precise surface temperature settings that no latex or coil mattress can match. The frame construction is solid and well-made, with the padded faux leather upholstery providing a retro aesthetic that some buyers specifically seek out.
The tradeoffs are substantial. The waterbed is extremely low to the ground — multiple owners note that the platform needs to be raised with a higher pedestal for comfortable entry and exit. The assembly is complex compared to a standard bed-in-a-box mattress, requiring frame construction, water filling, and heater installation. The waterbed is not an all-natural mattress by material standards — the water mattress uses vinyl, and the fiber layers are polyester-based. If your primary goal is all-natural material purity, this does not fit that definition.
What works
- Temperature control via water heater provides year-round climate regulation
- Waveless fiber layers reduce motion transfer better than most hybrid mattresses
- Complete system includes frame, heater, liner, and fill kit for one-box setup
What doesn’t
- Very low ground height means most users will need a higher platform
- Not an all-natural mattress — uses vinyl water bladder and polyester fiber
Hardware & Specs Guide
GOLS vs GOTS Certification
GOLS (Global Organic Latex Standard) certifies that the latex content is at least 95% organic raw material from rubber trees, with the remaining 5% limited to non-organic natural ingredients. GOTS (Global Organic Textile Standard) certifies organic fiber content in cotton and wool — anything labeled organic cotton or organic wool must carry GOTS certification, or the word “organic” is unregulated marketing. A mattress that lists both GOLS and GOTS certifications guarantees that every layer from the latex core to the cover thread is verifiably organic.
ILD and Firmness Mapping
ILD (Indentation Load Deflection) is measured by pressing a 4.5-inch diameter plate into a latex sample until it compresses 25%. An ILD of 14-19 corresponds to soft/plush (suitable for side sleepers under 150 lbs), 20-28 is medium (works for combination sleepers), and 29-40 is firm (ideal for back and stomach sleepers or heavier individuals). Most all-natural mattresses in this guide fall in the 24-38 ILD range, with the medium-firm options clustering around 29-31 and the firm options at 34+.
Latex Thickness and Support
All-latex mattresses in the 8-9 inch range (Sleep On Latex) contain pure latex end to end — no base layer of polyfoam to bulk up the height. This means the ILD rating applies uniformly through the mattress. Hybrid builds with 2-3 inches of latex over coils provide a softer top layer with deeper coil support, which can feel more familiar to people used to innerspring mattresses. A hybrid with 3 inches of 24 ILD latex over pocketed coils will sleep softer than a solid 8 inch slab of 24 ILD latex.
Wool Density and Fire Safety
Organic wool batting serves as a Class 1 fire barrier because wool has high moisture content and nitrogen levels that inhibit combustion — it chars instead of igniting. The wool layer should be at least 1 inch thick and fully encase the mattress surface to meet 16 CFR 1633 without chemical treatments. Wool also wicks moisture, regulates temperature, and resists dust mites naturally. Some budget “natural” mattresses use a thin wool layer over polyurethane foam with chemical fire retardants — check for full wool encasement, not just a wool cover.
