Most people land on Talalay because it's marketed as the premium option. Talalay is whipped, vacuum-expanded, flash-frozen, and baked, which gives it an even, fluffy, springy feel. Dunlop is the older method: liquid latex poured into a mold and baked, denser and firmer. So the standard advice is Talalay for pillows, Dunlop for mattress cores.
That advice misses something important. Dunlop isn't one thing. There's continuous-pour Dunlop (the mass-production method behind most latex pillows on the shelf) and slow-pour Dunlop (the small-batch, slow-cure method behind the high-end ones). The gap between those two is bigger than the gap between Talalay and continuous-pour Dunlop. Slow-pour Dunlop comes down to density. Because it is poured slowly in small batches, every part of the block sets at the same density top to bottom, so every shredded piece in the pillow springs back like the next one.
Here's what changes when you put slow-pour Dunlop into the comparison.
What slow-pour Dunlop is, and why it matters
The core challenge with Dunlop production is sediment settling. As liquid latex cures, the denser rubber particles sink toward the bottom of the mold. In continuous-pour Dunlop, where slabs run several meters long and cure quickly under industrial timing, that settling shows up as inconsistent density. The bottom of the block ends up firmer than the top. Lay your head on a continuous-pour Dunlop pillow and you can feel the gradient.
Slow-pour Dunlop fixes that by running the process at a much smaller scale. The batch is short enough and cured slowly enough that the sediment doesn't have time or distance to settle. The block cures evenly top to bottom, with the same open-cell density throughout. That even, springy consistency is exactly what people go to Talalay for, and slow-pour Dunlop gets there too.
The other difference is the rubber itself. Slow-pour Dunlop tends to use 100% Hevea sap. Continuous-pour mass production often blends synthetic latex (SBR) into the mix to bring cost down and stabilize the pour. The blend isn't dangerous, but it changes the feel.
Slow-pour Dunlop vs continuous-pour Dunlop
| Feature | Slow-Pour Dunlop | Continuous-Pour Dunlop |
|---|---|---|
| Density throughout the block | Even top to bottom | Firmer at the base, softer at the top |
| Feel | Soft, springy, and even | Denser, firmer, "mattress core" feel |
| Rubber source | Typically 100% Hevea sap | Often blended with synthetic SBR |
| Cure time | Longer (slower process) | Faster (industrial timing) |
| Scale | Small batches | Mass production |
| Cost | Higher per pillow | Lower per pillow |
| Longevity | Up to a decade | 8-10 years typical |
The trade-off is straightforward. Slow-pour costs more per pillow because the process is slower and the batches are smaller. Continuous-pour is cheaper because the production scale absorbs the cost. The feel difference is real and shows up the first time you compare them side by side.
Can you change the height, and can you get more material?
Two different questions, and most brands answer only the first. A pillow that opens with nothing to put back in it goes flat on the same schedule as one that never opened.
Adjustability runs in both directions, and taking material out is the half most people use. Ours arrive full, with about 30% more than most owners keep, so you can shape the pillow to your own neck. Most owners start by taking some out and setting the height to their own shoulder. Refill bags exist for the other direction, years later, when the material has settled.
The evidence for adjustability got better in 2026. A randomised crossover trial put an adjustable-height pillow against four fixed ones, with 30 adults. It measured comfort, cervical muscle oxygen and recovery. The adjustable one came first on all three. Its authors put it this way: “DA pillows may enhance cervical oxygenation, adaptive neuromuscular control, and comfort compared with fixed-height systems.”
| Pillow condition | Comfort score (0-100) | Height | How we checked |
|---|---|---|---|
| Adjustable height, air-based | 75.5 | adjustable | Published trial, open access, read 15 September 2026. |
| Polyester fiber insert | 70.2 | fixed | Published trial, open access, read 15 September 2026. |
| Non-adjustable polyester | 69.1 | fixed | Published trial, open access, read 15 September 2026. |
| Memory foam insert | 66.3 | fixed | Published trial, open access, read 15 September 2026. |
| Latex insert | 61.1 | fixed | Published trial, open access, read 15 September 2026. |
| No pillow | 36.4 | none | Published trial, open access, read 15 September 2026. |
Two honest limits on that trial. The adjustable pillow it used was air-based rather than a fill you take out by hand, and the sample was 30 young adults. So it supports adjustability as a principle rather than testing any particular pillow, ours included. Worth noting too that its fixed latex insert scored lowest of the inserts, and a shredded latex pillow that opens at a zipper is the opposite construction.
Against that, here is what the market offers. 20 of 21 natural latex brands say the pillow can be opened. 9 say they sell a refill, 2 say they do not, and 9 publish wording that answers it neither way.

How we checked. A desk study. Every cell is the brand's own published wording, read on its own product page between February and May 2026, with no figure inferred and nothing taken from a review site or a marketplace listing. Where a brand publishes no figure the cell reads not published, and that counts as a finding, because a buyer reading that page cannot know it either. Our own row is graded by the same rule as every other. Prices and policies move, so the price columns are the capture-window figures and not a live quote. The disclosure counts are what this study is about and they move far more slowly.

Slow-pour Dunlop vs Talalay
This is where it gets interesting. Slow-pour Dunlop and Talalay give you the same feel to sleep on, they just arrive there by different routes.
| Feature | Slow-Pour Dunlop | Talalay |
|---|---|---|
| Feel | Soft, springy, and cushioning | Soft and springy |
| Density | Even and consistent, top to bottom | Even |
| stays cool | Open-cell and shredded, so air moves through all night | Aerated and breathable |
| Purity | 100% Hevea sap, no fillers | Sometimes blended with synthetic SBR |
| Process | Simple: pour and cure | Complex: whip, vacuum, flash-freeze, bake |
| Longevity | Up to a decade | 8 to 10 years |
| Cost | Premium | Premium |
Both give you the soft, springy, even feel that makes latex worth sleeping on. The difference is everywhere else. Slow-pour Dunlop is 100% Hevea, holds that feel years longer, and because it is shredded and adjustable you can pull a few pieces out for as much plush give as you want. Same feel Talalay is known for, same price, and it lasts longer.
Choosing between the three
Slow-pour Dunlop is the pick for most sleepers. You get the same soft, springy feel people go to Talalay for, for the same price and with a few extra years of life. And because a shredded slow-pour Dunlop pillow is adjustable, it fits the widest range of sleepers. Take pieces out for a low, soft profile if you sleep on your stomach, or keep it full and plush for the shoulder height side sleepers need.
Talalay is the pricier route to the same feel. It sleeps just as soft and springy, but it costs the same or more and wears out a few years sooner. If you love the feel of latex, slow-pour Dunlop gives you that feel and holds it longer.
Continuous-pour Dunlop is the budget end. It sleeps firmer, with a denser feel at the base of the block, and it costs the least to make. Fine if you want a firm surface under your head and don't mind that density gradient.
The mistake most buyers make is choosing between just Talalay and continuous-pour Dunlop, never realizing there's a slow-pour version that combines most of the strengths of both. That's the version we built the Tree-Tapped Latex Pillow around.
Why we use slow-pour Dunlop for the Tree-Tapped Latex Pillow
Our latex pillow is shredded slow-pour Dunlop. The sap is tapped in Sri Lanka, through a shallow downward cut that opens the vessel network without harming the tree, so the same tree keeps producing for decades. It is poured there too, slowly and in small batches, so the denser rubber does not sink and the block cures evenly top to bottom. The block is fully cured before it is shredded, and the pillow is cut, filled and sewn by hand in New Jersey. The choice came down to three things.
First, even density. We didn't want a pillow that felt firmer on the bottom of the block than the top, which is what you get from continuous-pour Dunlop. The slow-pour method cures uniformly, so the shredded pieces are all the same density regardless of where in the block they came from.
Second, 100% Hevea sap, certified to the strictest tier. The pillow's finished latex is OEKO-TEX Standard 100 at Class 1, the strictest tier in the program. Class 1 means the latex was tested to the same safety threshold used for products designed for direct contact with infants and babies, covering more than 1,000 harmful substances including carcinogens, heavy metals, pesticide residue, formaldehyde, and phthalates. Most natural latex pillows that carry Standard 100 sit at Class 2 or Class 3 instead. Pure Hevea sap is part of how the pillow earns the Class 1 tier. The upstream rubber-tree source is also FSC certified (Forest Stewardship Council), which means the sap comes from independently audited responsible-forestry plantations in Sri Lanka.
Third, the shredded format. A solid latex block traps heat. Shredding the cured block into pieces leaves space for air to move continuously through the pillow, which is why ours runs cooler than solid latex and a long way cooler than memory foam. The shredded format also makes the pillow adjustable. Unzip the short end, remove or add pieces, set your height.

Q: What's the difference between slow-pour and continuous-pour Dunlop latex?
Slow-pour Dunlop is made in small batches over a longer cure time. Continuous-pour is the mass-production version, where liquid latex flows down a long mold and bakes as it moves. The denser rubber sinks during the cure in continuous-pour, leaving the slab firmer on one side than the other. Slow-pour cures evenly top to bottom because the batch isn't long enough or large enough for sediment-settling to show up. The result is a more uniform, springy block.
Q: Is slow-pour Dunlop as good as Talalay?
Yes, and for a pillow it is arguably the better choice. Slow-pour Dunlop gives you the same even density and soft, springy feel as Talalay, because the slow cure prevents the sediment-settling that makes ordinary Dunlop firmer at the base. The feel to sleep on is the same. What differs is everything around it: slow-pour Dunlop is 100% Hevea, lasts up to a decade, and sits at the same price. Same feel, longer life, purer latex, same cost.
Q: Why don't more latex pillow brands use slow-pour Dunlop?
Cost. Slow-pour Dunlop is made in small batches at a slower pace, which scales poorly to mass production. Most latex pillow brands optimize for unit cost and use continuous-pour Dunlop or solid Talalay slabs. Slow-pour requires a workshop-scale operation with longer cure times and more careful quality control per batch.
Q: Is slow-pour Dunlop blended with synthetic latex?
No. Slow-pour Dunlop is made from 100% Hevea sap. The synthetic (SBR) blends show up in continuous-pour mass production, where they bring cost down and stabilize the pour.
Q: How long does a slow-pour Dunlop latex pillow last?
Up to a decade with normal use, and you can add fresh latex through the zipper to keep it going. The denser, more uniform cell structure resists compression and breakdown better over time. Latex pillows also outlast cotton (2-4 years), wool (3-5 years), and memory foam (5-7 years) by a wide margin.
Q: Is slow-pour Dunlop latex pillow good for hot sleepers?
Yes, especially in shredded form. The open-cell structure lets air circulate through the pieces continuously, which keeps the pillow cooler than memory foam or solid latex slabs. Among natural fills, buckwheat runs slightly cooler than latex because of the airflow between hulls, but shredded slow-pour Dunlop is the next coolest option.
Q: What does OEKO-TEX Standard 100 Class 1 mean on a natural latex pillow?
OEKO-TEX Standard 100 is a finished-material safety test for more than 1,000 harmful substances, including PFAS, formaldehyde, heavy metals, pesticide residue, and phthalates. Inside the program there are four tiers (Class 1 through Class 4). Class 1 is the strictest, tested to the same safety threshold used for products designed for direct skin contact with infants and babies. Most natural latex pillows that carry Standard 100 sit at Class 2 or Class 3. The Tree-Tapped Latex Pillow's finished latex is certified at Class 1, which is part of why we framed the comparison around the slow-pour method and 100% Hevea sap.
Q: What does FSC certification mean for a latex pillow?
FSC is the Forest Stewardship Council standard for responsible forestry. On a natural latex pillow it applies to the rubber-tree source. The Hevea brasiliensis plantations our latex comes from are FSC certified, which means the tapping happens under independently verified responsible-forestry standards. Most natural latex pillows can claim OEKO-TEX Standard 100 on the finished latex but cannot claim FSC on the upstream supply chain.
Q: Can someone with a latex allergy use a slow-pour Dunlop pillow?
No. If you have a latex allergy, you should not use any latex pillow, whether slow-pour Dunlop, continuous-pour Dunlop, or Talalay. The allergy is triggered by proteins in the latex itself, and those proteins are present in all natural latex. The organic cotton pillow, kapok pillow, or wool pillow would be safe alternatives.
