Organic Latex Mattress: Custom Natural Layers

Dunlop and Talalay are two ways of processing natural latex rubber into foam. Both come from the same raw material, the sap of a rubber tree, but feel different in bed.

Dunlop latex is denser and more supportive. It has a slightly firmer feel and works great as a base or support layer. Our GOLS-certified organic latex is Dunlop.

Talalay latex goes through an extra vacuum-sealing and flash-freezing step that creates a more consistent, airy cell structure. The result is a bouncier, more pressure-relieving feel. Most people prefer it as a comfort layer.

Many of our customers use a mix of both: Talalay on top for cushioning and Dunlop underneath for support. When you personalize your mattress, we’ll recommend the best combination for your body type and sleep position.

We build three heights, each made of stackable 3-inch latex layers (the quilted cover adds the final inch):

• The Sprout (7″, 2 layers): Great for children, guest rooms, bunk beds, or anyone who prefers a firmer sleep surface.
• The Leaf (10″, 3 layers): Our most popular build. Three layers let you fine-tune firmness and create distinct comfort and support zones.
• The Tree (13″, 4 layers): Our premium build for maximum cushioning. Best for heavier sleepers (250+ lbs) or couples with very different firmness needs.

Not sure? Get a free recommendation and we’ll suggest the right height for you.

Unlike most mattresses, we let you customize each 3-inch layer individually. Soft comfort layer on top with firm support underneath, or any combination you want.

Our current firmness scale is X-Soft/Extra Soft Talalay 14-19 ILD (top comfort layer only), Soft 19-22, Medium 30-32, Firm 37-40, and X-Firm/Extra Firm 44. Higher ILD = firmer.

Three factors matter most:

• Sleep position: Side sleepers need softer top layers. Stomach sleepers need firmer.
• Body weight: Heavier sleepers compress the foam more, so a “medium” may feel soft.
• Personal preference: Some people just like a firmer or softer bed.

Our advice: Go slightly softer than you think. You can always rearrange layers to increase firmness.

Side sleepers need a softer comfort layer to cushion shoulders and hips. We recommend Soft or X-Soft Talalay on top with medium or firm support beneath.

Back sleepers need balanced contouring and support. A Medium top layer with a Medium or Firm base works well.

Stomach sleepers need a firmer surface to prevent hips from sinking. A medium or firm top layer with a firm layer underneath tends to work best.

Combination sleepers benefit from a responsive Talalay top layer that adapts quickly as you switch positions.

These are starting points. Tell us about your sleep and we’ll dial in the right setup.

Absolutely, and there’s no extra charge. On Queen, King, and Cal King sizes we can split every layer down the middle, so each side has a completely different firmness configuration.

For example, one side could be X-Soft Talalay over Medium Dunlop, while the other side is Medium Talalay over Firm Dunlop. You each get your ideal mattress without compromise.

The split is seamless. There’s no gap or ridge down the middle, and both sides share the same organic cotton and wool cover.

They’re very different materials:

• Temperature: Latex has an open-cell structure that breathes. Memory foam traps heat.
• Responsiveness: Latex bounces back immediately. Memory foam slowly molds.
• Durability: Natural latex lasts 15-25 years. Memory foam lasts 3-7.
• Off-gassing: Memory foam releases VOCs for days or weeks. 100% natural latex has no chemical off-gassing.
• Materials: Our latex comes from rubber trees. Memory foam comes from petrochemicals.

Innerspring mattresses use steel coils for support, which creates pressure points wherever the coil pushes back against your body. Natural latex conforms to your curves instead: no pressure points, no squeaking springs, no partner disturbance from bouncing coils.

Innersprings also trap dust, allergens, and moisture inside the coil chamber over time. Latex is solid foam with an open-cell structure. Nothing collects inside it. Durability isn’t close either: innerspring mattresses typically last 5-8 years before coils start sagging. Natural latex lasts 15-25 years.

If you weigh 250 lbs or more, we recommend our 13-inch Tree model (4 layers). The extra layer gives you more material to distribute your weight across, which prevents bottoming out.

For firmness, heavier sleepers typically need firmer layers than they’d expect. A “medium” latex layer feels soft when you compress it more. We usually recommend a Medium or Firm Talalay top layer with Firm or X-Firm Dunlop support layers underneath.

Our personalization form factors in your weight automatically and recommends the right configuration.

Yes, latex is one of the best mattress materials for adjustable bases. Unlike rigid innerspring mattresses, natural latex flexes easily with the base as it moves. It won’t crack, crease, or lose its shape over time.

We carry Ergomotion adjustable bases that pair perfectly with our mattresses. Any quality adjustable base with a flat, slatted surface will work.

Have a split base where each side moves on its own? Choose Split King (two Twin XL mattresses) or Split Cal King (two 36″ x 84″ mattresses) in the builder. Each side is its own mattress with its own cover, and each partner picks their own layers.

It means the latex is made entirely from the sap of rubber trees with no synthetic fillers, petroleum-based foams, or chemical additives.

Be careful when shopping. Many companies use terms like “natural” or “plant-based” on mattresses that actually contain synthetic latex. If a brand doesn’t specify “100% natural” or show third-party certification, the latex likely contains synthetics. For the full breakdown of terms and certifications, read our buyer’s guide to natural latex.

Both come from rubber tree sap and feel the same in bed. The difference is certification.

Organic latex is certified by GOLS (Global Organic Latex Standard) with strict rules for the entire supply chain. GOLS-certified latex must contain at least 95% certified organic raw material.

100% natural latex is the same high-quality material without the organic certification.

We offer both. In our mattress builder, every Dunlop layer is GOLS-certified organic latex at no additional cost. (Note: organic Talalay doesn’t exist because the Talalay process can’t meet GOLS requirements, but our Talalay is still 100% natural.)

Yes. Latex is natural rubber. It comes from the sap of rubber trees. “Rubber mattress” and “latex mattress” mean the same thing.

Synthetic latex (SBR) is a petroleum-based foam mixed with natural latex designed to imitate natural latex. It’s cheaper but contains the same chemicals found in conventional and memory foam mattresses.

Blended latex mixes natural and synthetic, typically 30% natural and 70% synthetic.

Always look for 100% natural or GOLS-certified organic. Sleeping Organic uses only 100% natural and certified organic latex, never synthetic or blended.

Our materials are tested and certified by multiple independent organizations:

• GOLS (Global Organic Latex Standard): The gold standard for organic latex worldwide.
• OEKO-TEX Standard 100: Tests for harmful substances.
• eco-INSTITUT: European lab testing for VOC emissions, heavy metals, biocides, and fire retardants.
• LGA Quality Certificate: Independent testing for chemical safety and product lifecycle.

Every certification involves independent, third-party testing.

Our cover has two layers:

• Outer fabric: Organic cotton. Soft, breathable, and free of chemical treatments.
• Inner lining: Natural eco-wool quilted into the cotton. Serves as a natural fire barrier and regulates temperature.

A full-length zipper lets you rearrange, swap, or replace individual latex layers anytime.

Every material in our mattress is independently tested and certified free of the harmful substances covered by our certifications:

• Latex: 100% natural rubber tree sap, no petroleum, no polyurethane, no synthetic fillers
• Cover: Organic cotton and natural eco-wool, no chemical flame retardants, no bleach, no pesticide-treated fabrics
• Adhesives: None. Our layers are stacked inside the cover, not glued together

We carry OEKO-TEX Standard 100, eco-INSTITUT, and GOLS certifications, all requiring independent lab testing for harmful substances. If clean materials matter to you, this is as transparent as mattress making gets.

Four things set us apart:

• True layer-by-layer customization. Most organic brands offer soft, medium, or firm, one firmness for the whole mattress. We let you choose a different firmness for every single layer, and split each layer for couples.
• You can adjust it yourself, forever. Our zippered cover means you can rearrange, swap, or replace individual layers anytime. Your mattress evolves with you instead of being a one-time purchase you’re stuck with.
• You choose exactly how you want your mattress designed. Dunlop or Talalay or a mix.
• Factory-direct pricing. We manufacture in-house and sell direct. No retail markup. A comparable custom organic latex mattress from a showroom brand typically costs 2-3x more.

No, sleeping cool is one of latex’s biggest advantages. Natural latex has an open-cell structure. Air flows freely instead of getting trapped.

Our organic cotton and wool cover helps too. Wool wicks moisture away in warm weather and insulates in cold weather.

No. Off-gassing comes from petroleum-based foams. Our mattress contains zero petroleum-based materials.

You may notice a mild, natural scent when first unboxed, similar to hay. It’s simply the natural scent of latex and fades within a day or two. You can sleep on it the same day it arrives.

Most people with latex sensitivities can sleep on a natural latex mattress safely. During manufacturing, extensive washing removes nearly all allergy-causing proteins. You also never touch the latex directly. It’s fully enclosed in the cover, sheets, and protector.

If you have a severe latex allergy (anaphylaxis risk), consult your doctor first. Call us at (800) 625-4042.

Many customers with back pain tell us it helps. Natural latex contours to your body (relieving pressure points) while providing firm support for spinal alignment.

Our layer system lets you dial in the right balance. Softer top for hip and shoulder relief. Firmer base to prevent sagging. And you can rearrange layers as needs change.

Tell us about your back issues and we’ll recommend a configuration.

Most people feel comfortable right away. We recommend giving it at least 30 nights to fully adjust, especially if switching from memory foam or innerspring.

If something doesn’t feel right, rearrange your layers or contact us for free guidance. You’re never stuck. Layers are individually swappable.

Yes. We offer wool-free cover options. Because wool serves as our natural fire barrier, some options may require a documented prescription.

Call us at (800) 625-4042 or email us to discuss options.

Very little. Natural latex absorbs movement rather than transferring it across the bed. If your partner tosses and turns, you’ll feel far less disturbance than with an innerspring or even most memory foam mattresses.

For couples with very different sleep schedules, our split-layer option helps even more: each side has its own independent layers, further isolating movement.

Absolutely. Natural latex is one of the safest mattress materials for children: no petroleum chemicals, no VOC off-gassing, no synthetic flame retardants. Our 7-inch Sprout model is popular for kids’ rooms and bunk beds.

The organic cotton and wool cover is naturally hypoallergenic and resistant to dust mites. And because latex resists body impressions, it provides consistent support as your child grows.

Yes, this is one of the most common reasons customers switch to natural latex. Side sleepers need a mattress that lets the shoulder sink in enough to relieve pressure without losing spinal alignment.

We typically recommend an X-Soft or Soft Talalay top layer for shoulder relief, with a firmer Dunlop base layer for support. The combination cushions the shoulder joint while keeping your spine straight. Tell us about your shoulder pain and we’ll recommend a specific setup.

Natural latex mattresses are significantly heavier than conventional mattresses. Approximate weights by size and height:

• 7″ (2 layers): Twin ~45 lbs, Queen ~75 lbs, King ~90 lbs
• 10″ (3 layers): Twin ~65 lbs, Queen ~105 lbs, King ~130 lbs
• 13″ (4 layers): Twin ~85 lbs, Queen ~140 lbs, King ~170 lbs

The weight is actually a quality indicator. It means you’re getting dense, durable natural latex instead of lightweight synthetic foam. Each layer ships in a separate box (max ~55 lbs each), so setup is manageable.

A well-cared-for natural latex mattress lasts 15-25 years, about 3x longer than memory foam or innerspring.

Natural latex resists permanent body impressions. Plus, each layer is individually replaceable, so you can swap one worn layer instead of replacing the whole mattress.

We do not offer traditional send-it-back returns or refunds on custom mattresses. Every mattress is built to your exact specifications when you order, so instead of a return window we designed a better fix: the 365-Day Comfort Program.

If the feel is not right, you have a full year to correct it. First, rearranging your layers through the zippered cover is free and solves many comfort issues. If a layer truly is not right for you, you can purchase up to two replacement layers in your first year at 30% off the lowest sale price, and you keep the originals. A single layer costs a fraction of a full mattress, and because the layers are unglued, changing one changes the feel.

Two honest caveats: replacement layers are discounted purchases, not free exchanges, and there is no option to send the whole mattress back for a refund. In exchange, you get a full year instead of a 90-100 night window, nothing goes to a landfill, and manufacturing defects are covered separately by the 20-year warranty.

Every mattress includes a full year to fine-tune your setup:

1. Sleep on it for at least 30 nights.
2. Try rearranging your layers. Move a firmer layer up or a softer layer down through the zippered cover.
3. Contact our sleep specialists for guidance. We will help identify the right comfort adjustment for you.
4. If a swap is needed, purchase up to two replacement layers during your first year at a deeply discounted Comfort Program price and keep the original layers.

See the full 365-Day Comfort Program details.

Cover: Do not machine wash. Spot clean with warm water and mild soap, then air dry.

Latex layers: Spot clean with warm soapy water or white vinegar solution. Make sure latex is completely dry before re-covering.

Important: Never put latex in direct sunlight. UV causes oxidation and breakdown.

Best care: use a mattress protector.

We strongly recommend one. Your organic cotton cover is not waterproof or machine-washable.

Our organic waterproof mattress protector won’t change the feel or make it sleep hot.

Your mattress needs a solid, flat surface:

• Wood foundation or slatted platform: Slats no more than 3″ apart. Our Heavy-Duty Latex Mattress Foundation has 18 slats under 1.75″ apart, a 2,000 lb rating and a lifetime warranty. Use it on its optional legs, inside your current bed or on a metal frame.
• Solid platform bed: Any flat, sturdy surface.
• Adjustable base: Latex works great with adjustable beds.
• Floor: Works, but a foundation improves airflow and longevity.

Avoid coil box springs. Poor support underneath is one of the most common causes of mattress sagging.

You don’t need to flip it, but you can rearrange the layers inside. That’s the advantage of our design. If one layer softens over time, move it to a lower position or swap it out entirely. You can also rotate the mattress 180 degrees (head to foot) every few months to even out wear, though natural latex resists body impressions far better than foam or innerspring.

Yes. This is one of the biggest advantages of our layer system. If you gain or lose significant weight, your firmness needs can change. With a conventional mattress you’d need to buy a new one. With ours, simply rearrange the layers: move a firmer layer closer to the top for more support, or a softer layer up for more cushion. If that is not enough, our 365-Day Comfort Program lets you purchase up to two replacement layers during your first year at a deeply discounted Comfort Program price instead of replacing the entire mattress.

Yes, and this is a major cost advantage over conventional mattresses. If one layer wears out after 10+ years, you replace just that layer (starting around $150-$300 depending on size and type) instead of buying a whole new mattress. The other layers, the cover, and the overall structure keep working. It’s like replacing one tire instead of buying a new car.
