Mattress ships and delivers flat. It is not compressed or roll-packed.

Weight Support: Up to 550 lbs per person, or 1,100 lbs total. Two full coil units instead of one — 1,600 individually wrapped coils in Queen, all 14-gauge double-tempered recycled steel, separated by an organic coconut fiber pad infused with GOLS-certified organic latex. The highest weight capacity of any GOTS-certified organic mattress. Queen and larger require a rigid center support beam with at least one leg to the floor; our Heavy-Duty Foundation (low and standard profile) adds more slats, up to four interior support bars, and 12 leg supports, and is rated to 2,000 lbs of total load.

The firmest mattress we offer. Purpose-built for big-and-tall sleepers, plus-size individuals, athletes, and anyone who prefers an ultra-firm sleep surface, this mattress delivers maximum support without compromise. It resists sagging and ensures your body remains aligned all night long. There’s no sink, no bounce — just solid, consistent support across the entire surface. See: Which Firmness is Right for Me?

Our Dunlop latex carries both GOLS certification (CU 863637) for organic content and FSC® certification (FSC-C156318) for responsible plantation management. It's sourced from co-owned farmer societies and processing facilities in India and Guatemala operating under the USDA's National Organic Program, with 95% or more certified organic content and processing in GOLS-certified facilities.

In the Extra Firm, we use D65 — our firmest Dunlop density, perforated and ventilated so air moves through it rather than sitting against your body. It sits directly on the coconut fiber pad and carries load with it; there's no soft transition layer here. Also eco-INSTITUT® label certified (119-34212-001), confirming low emissions and pollutant content.

A one-ounce-per-square-foot layer of pure organic wool sits beneath the cotton cover, certified to the Responsible Wool Standard by Textile Exchange® for animal welfare and land management. Wool does three things here. It wicks moisture away from the surface, which matters more the warmer you sleep. It resists odor, so the mattress stays fresh without treatment. And it passes federal flammability standards on its own — which is why there are no chemical flame retardants in this mattress, and no rayon or polyester blended into the wool to get there. It's also a renewable material and an alternative for anyone sensitive to down or synthetic bedding. Learn more about the sourcing story, certifications, and benefits of our organic wool. 

For a luxurious and premium finish, we use GOTS-certified organic cotton (CU863637) in a soft, natural color blended with 3% elastane for functional stretch and enhanced durability—fully compliant with GOTS standards. This fabric is quilted over a generous layer of organic wool, supported by a thin, non-woven backing—added in accordance with GOTS accessory requirements—to prevent the wool from shifting or clumping and to keep natural fibers from working through the outer cotton over time. Responsibly and ethically sourced from India, this durable textile is hand-needle-tufted using organic wool yarn rosettes. These secure the cotton ticking and internal mattress layers without chemical or water-based adhesives. Reinforced edge seams are double-stitched for added durability, and four heavy-duty upholstered handles make the mattress easy to rotate or move. Organic cotton complements the wool comfort layers, ensuring this mattress sleeps cool without synthetic fabrics or flame retardants.

The Avocado Extra Firm Mattress features a purpose-built, heavy-duty support system that delivers exceptional firmness, pressure relief, and long-term durability. Rather than relying on thick synthetic foam layers, this mattress features a dual-coil construction separated by natural coconut fiber pads, designed to meet the needs of heavier sleepers, big and tall individuals, athletes, or anyone who prefers an ultra-supportive mattress.

The mattress includes two 3-inch layers of individually wrapped, heavy-gauge coils, each floating independently within a food-grade, non-woven polypropylene fabric. We manufacture these coil units ourselves rather than buying them from a spring supplier — which is why both units run uniform 14-gauge double-tempered recycled steel instead of whatever a catalog offers.

Three 0.5-inch layers of organic coconut fiber infused with organic latex run through the mattress: one above the top coil unit, one between the two units, and one below the bottom. The top pad stiffens the surface beneath the latex. The middle pad keeps the two coil units from nesting into each other, so they behave as a single rigid structure rather than two stacked springs. The bottom pad spreads load across the foundation. All three are dense enough to add firmness while staying open enough for air to move, and none of them is glued in place.

The coils are assembled using an environmentally conscious adhesive composed of tested components (Waxes: CAS 8002-74-2, Resin: CAS 8050-26-8, Antioxidant: CAS 6683-19-8, EVA Polymer: CAS 24937-78-8). They are needle-tufted by hand with up to 9 wool rosettes, eliminating the need for chemical flame retardants or glues between layers.

The entire innerspring system is part of the finished mattress that meets OEKO-TEX® STANDARD 100, EWG Verified®, MADE SAFE®, GREENGUARD Gold, and UL® Formaldehyde-Free Claim Verification standards, ensuring the mattress is held to the most rigorous standards for environmental safety and human health. With its advanced dual-coil design and ultra-firm feel, the Extra Firm Mattress delivers unmatched support, durability, and breathability, making it the ideal mattress for plus-size sleepers, back and stomach sleepers, and those seeking a firm, organic mattress that performs.
