If you've spent any time researching latex mattresses, you've run into the Dunlop vs Talalay question. Both come from natural rubber tree sap. Both are used in latex mattresses. But they're made through different processes and they perform differently, and the distinction matters when you're choosing a mattress or deciding whether to add a topper.
Sleep Majestic uses both. Understanding which is which, and why, is the most useful piece of latex education a buyer can have before making a decision.
How Dunlop Latex Is Made
Dunlop is the older of the two processes, developed in 1929. Liquid latex sap is whipped into a froth, poured into a mould, and vulcanised with steam heat. During this process, natural sediment in the latex settles toward the bottom of the mould before it sets. The result is a foam that's slightly denser at the base than the top, though this variation is minor in a finished mattress.
The Dunlop process is simpler than Talalay and produces a denser, more supportive foam. GOLS (Global Organic Latex Standard) certification applies to Dunlop latex. All of Sleep Majestic's Dunlop latex carries GOLS, Eco-Institut, and Oeko-Tex certification, sourced from India and Sri Lanka.
How Talalay Latex Is Made
The Talalay process builds on Dunlop with two additional steps. After the latex is poured into the mould, the mould is sealed and the air is vacuumed out, which expands the latex to fill every corner evenly. The foam is then flash-frozen with CO2 before vulcanisation. This produces a more consistent cell structure throughout and a lighter, more open feel than Dunlop.
The extra steps make Talalay more expensive to produce. The result is a latex that's generally softer and more pressure-relieving than Dunlop at the same ILD (Indentation Load Deflection) rating. Sleep Majestic sources Talalay from the USA. It's available as fully natural (Natural Talalay) or as a natural and synthetic blend (Original Talalay). The blend achieves a softer feel than fully natural latex can; 100% natural Talalay is slightly firmer. GOLS certification does not apply to Talalay.
How the Feel Differs in Practice
Dunlop has what the industry calls a more supportive feel: it pushes back evenly under pressure, with a resilient quality that suits back sleepers and combination sleepers who need consistent support. It compresses and returns quickly, and holds its shape over time without developing body impressions.
Talalay feels lighter and more conforming. Side sleepers often prefer it as a comfort layer because it provides more give at the shoulder and hip. It's also more breathable than Dunlop due to its open cell structure, which suits warm sleepers who want a softer surface.
How Sleep Majestic Uses Both
Dunlop goes into all base layers across the 100% latex and hybrid lineup. Its density makes it the right material for structural support. In the 10" 100% Organic Dunlop Latex Mattress, the 6" base is Firm or Extra-Firm Dunlop, with the transition and comfort layers also in Dunlop. Firmness options run from Soft through Extra-Firm.
Talalay enters as a comfort layer option in the 10" Dunlop/Talalay Latex Mattress, pairing a 6" Dunlop base with a 2" or 3" Talalay top. It's also available as a comfort layer in the 11" DIY Dunlop/Talalay Hybrid. As a comfort layer, Talalay is available in Soft only.
On the topper side, the Organic Dunlop Latex Topper comes in Soft, Medium, and Firm in 2" and 3" thicknesses and carries GOLS certification. The Original Talalay Latex Topper and Natural Talalay Latex Topper are both Soft only, carry Oeko-Tex certification, and are sourced from the USA.
Which One Is Right for You
The practical answer depends on sleeping position. Back sleepers do well with Dunlop across the full mattress. Side sleepers often benefit from Talalay in the comfort layer for pressure relief at the shoulder and hip. Stomach sleepers need an Extra-Firm Dunlop core and generally don't benefit from Talalay, which is too soft for that position.
The best way to feel the difference is at the Delta showroom, which has full-size models of both the 10" 100% Dunlop and the 10" Dunlop/Talalay Latex Mattress. For those outside Metro Vancouver, a phone fitting is the practical alternative.
Dunlop is denser, more supportive, and GOLS-certified. Talalay is lighter, softer, and better suited as a comfort layer for side sleepers. Sleep Majestic builds with both, using each where its properties are the right fit. The 10" Dunlop/Talalay Latex Mattress combines both in a single build and is the model that most clearly shows the difference. It's available to try at the Delta showroom, or start with a phone fitting if you're outside Metro Vancouver.
