Naturally, I was intrigued when Nolah sent me their Natural 11 hybrid mattress to test and review for eachnight.com.In this detailed assessment, I’ll walk through my hands-on experience sleeping on and evaluating nearly all aspects of this eco-friendly latex hybrid.

Claim Deal Mattress Construction: Quality Materials and CraftsmanshipUnboxing the Nolah Natural 11, I immediately noticed the quality craftsmanship and materials used. This thoughtfully designed 11-inch thick hybrid mattress contains responsive Talalay latex layers reinforced by a zoned pocketed coil system for contouring comfort and robust support.Starting from the exterior, the latex mattress is wrapped in a soft and breathable GOTS-certified organic cotton cover. Cotton offers temperature regulation and moisture wicking for cooler sleep, and the GOTS standard ensures environmentally sustainable processing methods were used.Beneath the cover rests a gentle wool fire barrier layer for added temperature neutrality, cushioning resilience, and certified chemical safety. As a naturally flame-retardant fiber meeting strict safety standards, wool enables mattress makers to avoid chemical flame retardants.Progressing inward, a plush 2-inch Talalay latex comfort layer cradles the body to relieve tension around common pressure points in side sleepers. Harvested from rubber trees, Talalay latex offers superior pressure relief over synthetic foams and even other types of natural latex. Its open-cell structure and Talalay production method make it ultra-responsive, breathable, and durable over years of consistent use.A 1-inch transitional Talalay latex layer provides a bit firmer reinforcement under the plush top while still retaining pleasant responsiveness. This smart layering prevents excessive sinking for proper spinal alignment through the midsection.Together with the comfort layer, the Nolah Natural’s 3 total inches of buoyant, contouring Talay latex supply the “hug” many sleepers enjoy from foam but with quicker adaptation to movements.Forming the core base layer is an 8-inch pocketed coil system divided into three distinct support zones. Hundreds of fabric-encased coils provide sturdy reinforcement for sleepers while permitting targeted pressure relief. The zones—softer shoulders, firmer hips, and medium firmness through the midsection—promote even alignment whether you snooze on your side, back, stomach, or all three!Finally, a thin layer of organic wool and cotton protects and stabilizes the coil base, improving durability and preventing impressions over years of regular use. The final bottom layer of organic cotton fabric features handles along the sides for easier carrying and lifting.With its blend of cushioning natural latex, reinforced edge support, and temperature-regulating botanical fibers, the Nolah Natural’s quality 6-layer construction impressed me from the start.Ideal for Combination Sleepers Of All PositionsAs an avid combination sleeper myself, I need versatility from my mattress for fluid transitions between side, back, and stomach sleeping. With a medium firmness rating around 5 to 6 on the typical mattress scale, the balanced Nolah Natural 11” proved comfortable in every position I tested.The plush latex layers cushioned my shoulders and hips effectively as a side sleeper while preventing excessive sinking around my midsection. Even bearing weight on one shoulder produced no uncomfortable pressure. For strict side sleepers under 150 pounds seeking more “hug”, a soft mattress topper could supplement the gentle contouring.Switching to my back, I felt fully supported in neutral alignment with no awkward shoulder or hip angles. The transition layer firmed things up just enough to meet my lumbar support needs, working as an good mattress for back sleeping.Stomach sleeping felt similarly comfortable thanks to the firmer core coils preventing hammocking around the midsection. Throughout my tossing and turning, the latex responsively conformed then rebounded quickly as I moved, cementing itself as an excellent mattress for combination sleeping.While personal firmness preferences vary, I’d recommend the Nolah Natural to strict side sleepers over 150 pounds and all combination sleepers under 300 pounds seeking reliable comfort in every snoozing position. The balanced medium feel avoids excessive softness or rigidity for all-around adaptability.If you sleep predominantly on your back or stomach though, you may prefer an extra-firm option to prevent sinking sensations.Responsiveness Promotes Changing PositionsResponsiveness is crucial because it ensures that the mattress adapts to the body’s contours, distributing weight evenly and alleviating pressure points. A responsive mattress for pressure points can conform to the curves of the body, providing support where needed and reducing the risk of discomfort or pain.As an indicator of how well a mattress physically responds to movements, I conducted a simple responsiveness test using 10-pound medicine balls. Dropping a ball from several heights above the mattress and watching the rebound speed shows how quickly its materials adapt to changes in pressure.After multiple drops, I scored Nolah’s responsiveness a perfect 10 out of 10. The latex layers bounced back instantly on impact demonstrating their rapid adaptation abilities. Coupled with the reinforced coils, pressure applied when changing positions doesn’t linger long before the mattress regains its natural shape. This quick reaction time prevents the “stuck in the mud” feeling some all-foam beds produce.For combination sleepers, seniors who change positions frequently, and bed partners on mismatched schedules, this responsiveness promotes effortless overnight movements. The Nolah Natural strikes an ideal balance between contouring pressure relief and the quick-adapting bounce latex is known for. Mattress Responsiveness Score 10 out of 10Mattress Motion Isolation: Slight Motion TransferMattress motion isolation is essential for minimizing disturbances caused by movement, making it particularly important for couples or individuals sharing a bed. By absorbing and dampening motion, such as tossing and turning, mattress motion isolation prevents disturbances from transferring across the bed, allowing both sleepers to rest undisturbed on a well-made mattress for couples.To measure a mattress’ motion isolation abilities, I conducted two more ball drop tests to simulate a partner changing positions. Dropping one ball, and then a second ball on the opposite side shows if and how motion gets transferred across the bed’s surface.Once these balls settle, I also climb onto the bed and stretch out as if I’m preparing to fall asleep. Then I gently roll about, as if I’m tossing and turning in sleep while observing how the weighted balls respond to my movements. In other words, if they stir without any direct contact occurring.With its substantial coil layer and buoyant latex comfort system, the Nolah Natural expectedly allowed some noticeable motion transfer but less than many hybrids. I scored this mattress with motion isolation an 8 out of 10 as lightweight sleepers will likely notice some side-to-side disturbance, but overall the mattress is quite serviceable when it comes to preventing the worst of motion transfer.For couples with extreme weight differences or sensitivity to movement, I’d likely recommend a firmer all-foam construction instead for minimal transfer. Motion Isolation Score 8 out of 10Sturdy Mattress Edge SupportHowever, what the coil system lacks in motion isolation it makes up for in superb edge support, as I learned firsthand sitting and lying along the mattress perimeter. I sank down barely an inch before feeling completely stable and supported near the edges, thanks to the perimeter-strengthened coils.Mattress edge support like this is crucial for several reasons. Firstly, it enhances the overall stability and durability of the mattress, preventing sagging and maintaining its shape over time.Additionally, strong edge support ensures that the entire sleep surface is usable, allowing individuals to sit or sleep comfortably near the edge without feeling like they might roll off. Moreover, robust edge support can make it easier to get in and out of bed, providing a secure surface for sitting or lying down.For using the full sleep surface without “rolling out of bed” fears, I scored the mattress a 9 out of 10 for edge support. Hybrid coil bases generally outperform foam beds in this regard, if you’re trying to decide between a hybrid or memory foam mattress. Edge Support Score 9 out of 10Natural Materials Regulate TemperatureSleeping hot is a top mattress complaint among those I consult with, but thankfully the Nolah Natural’s breathable design keeps warm sleepers like myself resting cool and comfortable. Three key temperature-regulating features work together to minimize heat retention and ensure a cooling mattress.First, the quilted organic cotton cover wicks moisture to keep the surface pleasantly dry. Natural wool fibers also distribute and dissipate body heat quickly before the heat builds up. Wool accomplishes this through its crimped protein structure enabling both warming and cooling.Finally, the aerated Talalay latex layers encourage upward airflow and heat dispersion, unlike dense memory foams.Between these cooling components and the consistent mild firmness suitable for most back and side sleepers, I awarded the mattress’ overall cooling performance and breathability a 9 out of 10.While adding a cool gel foam layer or similar cooling mattress topper could hypothetically improve heat diffusion even further, the mattress already sleeps exceptionally neutral year-round.If you’re a hot sleeper or living in warm climates though, I have reviewed mattresses that I feel promote a more thorough cooling feel, scoring a perfect 10 out of 10:Amerisleep AS2Amerisleep AS3Amerisleep AS3 HybridBrooklyn Bedding Aurora Luxe HybridFor most users, however, the Nolah Natural’s botanical materials provide more than sufficient sweat-free sleep. Temperature Regulation Score 9 out of 10Built to Last Many YearsConsidering the exceptional materials, quality construction, and reinforced support system outlined already, the Nolah Natural 11” appears built to provide many years of continuous comfort with minimal long-term body impressions or sagging.In fact, Nolah offers an above-average “Limited Lifetime Warranty” to back their durability claims and prove their confidence in lasting performance.A good mattress warranty indicates they are designed for long-term durability, after all. For the first 2 years, Nolah will fully replace a defective mattress at no charge.Between years 3 to 10, they will repair and re-cover a defective mattress for just $99 transportation fees. This demonstrates the confidence that materials like the foam and cover should last at minimum a decade without significant degradation if properly cared for.From years 11-25, Nolah prorates replacements at 50% off the current retail price for original owners of this durable mattress. And past the first 25 years, replacements are still discounted by 60% for verified defects. Offering discounted replacements well past typical full warranty periods shows Nolah expects their materials and construction to endure for decades in most cases.Nolah does specify weight limits and matching foundations needed to qualify for the warranty and prevent premature impressions or damage, however. Exceeding weight capacity voids coverage, as it can negate the measures that establish a mattress that won’t sag. Proper, supportive bases are also required.Compared to the typical 10 years of full coverage, Nolah’s lifetime proration demonstrates their belief in the long-lasting endurance of materials like thick latex layers and sturdy pocket coils. For such exceptional durability at a reasonable mid-range price point, the Nolah Natural earns high marks for projected longevity from this reviewer.Potential Drawbacks to ConsiderWhile I wholeheartedly recommend the Nolah Natural 11” for most hot sleepers based on the ample strengths just outlined, a few potential drawbacks are worth noting for shoppers seeking specific features.First, latex and pocket coils produce an exceptionally bouncy, responsive feel some initial users may not prefer. However, Nolah offers a generous 120-night trial to adjust to the buoyancy. As explained already, this signature latex responsiveness lets combination sleepers change positions effortlessly.Further, shoppers wanting an especially thick mattress exceeding 11 inches may view the Nolah’s profile as too shallow. I would suggest a hybrid like the Amerisleep AS5 Hybrid or the Zoma Boost in this case for maximum surface cushioning.Finally, the mattress does contain natural latex layers, so individuals with confirmedlatex allergiesVerified Source National Library of Medicine (NIH)World’s largest medical library, making biomedical data and information more accessible.View sourceshould avoid exposure. For most consumers though, these drawbacks shouldn’t outweigh such a thoughtfully constructed bed.Sleep Trial, Warranty, and PricesNolah comforts shoppers with lengthy 120-night sleep trials so users can judge the optimal fit and feel within their bedrooms. And Nolah makes it possible to remove this sleep trial at checkout for extra savings, if you’re looking for a budget mattress. However, I always advise clients to test beds in their own homes before fully committing since comfort is highly subjective and personal.If you decide this mattress with a free sleep trial isn’t suitable within 4 months, contact Nolah’s customer service team to initiate a return and request a different model or full refund. No re-stocking or shipping fees apply, so there’s minimal risk trying the Nolah Natural.As for pricing, the Nolah Natural is comparable to other latex hybrid mattresses I’ve reviewed:Amerisleep OrganicaBirch NaturalAnd all standard mattress sizes are available: twin to California king. Nolah’s comparatively budget-friendly prices increase their value proposition even further.On top of budget-friendly retail prices, every Nolah mattress comes protected by their Limited Lifetime Warranty for extra peace of mind. If any manufacturer defect emerges in your mattress, Nolah will repair or replace it entirely free of charge within the first 2 years. Past that, only small transportation fees apply for up to 10 years.Nolah Natural 11 Mattress Dimensions and PricesNolah Natural 11 SizeDimensionsPriceTwin Size38 inches wide by 74 inches long by 11 inches tall$1499Twin XL Size38 inches wide by 80 inches long by 11 inches tall$1699Full Size54 inches wide by 75 inches long by 11 inches tall$1899Queen Size60 inches wide by 80 inches long by 11 inches tall$2099King Size76 inches wide by 80 inches long by 11 inches tall$2499California King Size72 inches wide by 84 inches long by 11 inches tall$2499Split King SizeTwo mattresses 38 inches wide by 80 inches long by 11 inches tall$3398Split California KingTwo mattresses 36 inches wide by 84 inches long by 11 inches tall$3398 Get your own Nolah Natural 11 today and save up to 35% with our discount code Check Latest PricesCustomer ReviewsWhile I find comfort in my own mattress thoughts and observations, I’m cautious about recommending it without taking into account the diverse experiences of fellow sleepers. So I pulled up the customer reviews on Nolah’s web page, where the mattress holds a high 4.9 out of 5 stars.Scouring verified review sites and testimonials, Nolah earns shining feedback from wide-ranging customers praising everything from pressure relief to responsiveness to longevity:Susana Munoz highly recommends the Nolah Natural 11, describing it as a game changer for her and her husband. They were initially hesitant about making a large purchase of an online mattress but are now experiencing the best sleep of their lives. The mattress provides excellent motion isolation and temperature regulation, allowing them to sleep peacefully without overheating or feeling each other’s movements.Susan Quarmby expresses delight in her purchase of a Nolah Natural 11, likening the sleeping experience to “sleeping on a cloud.” She finds the quality of the mattress superior to her previous one and now enjoys sound sleep throughout the night. Although receiving and unboxing the shipment required assistance from two people, she found the process extremely easy.Louis Blasco enthusiastically rates the mattress with 5 stars. He describes how he can fall into a deep sleep and wake up in the same sleep position he fell asleep in, whether it’s on his side, back, or stomach. While he finds it challenging to categorize the firmness level, he asserts that it is the most comfortable bed he has ever slept in. Louis compares the experience to the Goldilocks condition, where everything feels just right.Not all sleepers were thrilled with the mattress, though. For example, there’s Irena Saundeen, a side and stomach sleeper who sleeps alone and noted the mattress was an improvement from her previous one. She gave the Nolah Natural three stars. However, she mentioned it took over 8 months for it to relax and become less firm.Despite being made of latex and advertised as temperature-neutral, Irena experienced heat retention issues, contrary to her expectations, which has been disappointing and an ongoing concern.Responsible Eco-Friendly ConstructionBeyond personalized comfort, part of what attracted me to Nolah is their admirable environmental commitment transparently communicated online. They consciously select sustainable, natural materials meeting verified safety standards to benefit both sleepers and the planet.For total confidence in mattress safety, ALL Nolah mattresses have synthetic foam layers that meet CertiPUR-US emissions and production standards or latex layers with an OEKO-TEX certification. Every Nolah mattress is also free of fiberglass.Nolah’s organic cotton and wool components hold GOTS organic certification, meaning non-GMO seeds were used and no toxic pesticides or fertilizers tainted fields during growth. These stringent standards ensure both sustainable agricultural practices and a chemical-free end product.The latex itself biodegrades fully without dangerous methane emissions created during synthetic foam breakdown. Even the pocketed coil bases employ durable recycled steel. Such conscientious material selections minimize the overall human and environmental impact compared to chemically-derived alternatives.Through their renewable, responsibly sourced materials meeting rigorous ecological standards, Nolah demonstrates admirable dedication to environmental stewardship within the mattress industry. Their transparency about chemical safety and sustainability on their website impresses me as both an eco-conscious consumer and a health practitioner.Easy Maintenance RecommendationsTo help your investment last, Nolah offers clear maintenance guidance to protect your mattress’s long-term performance. First, they suggest a waterproof mattress protector to shield the cover from spills and stains even though it’s not required on their 120-night trial.I tend to recommend encasements for all bed-in-a-box mattress purchases since most covers aren’t removable or washable. While mattresses in a box are usually affordably priced, that doesn’t mean you should sidestep care practices that can protect your investment.For regular cleaning, spot-treat stains immediately using just mild soap and warm water. Harsher chemicals could degrade the fire-resistant wool or organic cotton over time. After cleaning the mattress, let all the excess moisture air dry rather than soaking it up. Make sure it is completely dry before you re-dress the bed.Though Nolah doesn’t mandate flipping or rotating the mattress, I personally recommend rotating it head-to-toe a few times per year to minimize body impressions from concentrated weight. This easy 5-minute task extends durability and prevents dips, and with the Nolah Natural’s side handles it’s a simple chore.Finally, clean your mattress protector every six months and wash bedding weekly in hot water to eliminate the surface allergens that accumulate naturally on a bed. By coupling good hygiene habits with Nolah’s care recommendations, your investment will no doubt deliver years of healthy and comfortable sleep.The Final VerdictAfter extensively testing the Nolah Natural’s construction quality, comfort across positions, responsiveness, edge support, cooling properties, projected durability, and overall value, I happily award this thoughtfully engineered latex hybrid mattress a final score of 8/10.I admit part of my bias here is that the Nolah Natural 11 doesn’t quite match with what I want in a mattress, such as a taller bed profile. However, I do think that this is a well-crafted mattress that can suit many different types of sleepers.While absolutely no mattress offers universal perfection for every sleeper’s preferences, Nolah’s balanced foam and coil design should satisfy combination sleepers plus strict side, back, and stomach sleepers under 300 pounds seeking reliable comfort night after night. Hot sleepers and green shoppers can rest with certainty on this worthy mattress investment that protects both your wallet and your well-being.Nolah carefully selects high-quality sustainable materials to deliver durable ergonomic support and cooling for eco-conscious shoppers at every size and sleep style. Their exceptional lifetime warranty and glowing customer reviews instill further confidence.Dr. Jordan Burns’ Final Score TallyCategoryScoreMattress Responsiveness10 out of 10Motion Isolation8 out of 10Edge Support9 out of 10Breathability and Cooling Features9 out of 10Overall Score8 out of 10Frequently Asked Questions (FAQs)Is the Nolah Natural 11 suitable for all sleep positions?Yes, the Nolah Natural 11 is a versatile mattress that accommodates most sleep positions.
