From the moment you lie down, organic latex cradles your body — buoyant, breathable, and never heat-trapping like memory foam. Premium models layer in silky-soft Pure Talalay® latex for an even plusher feel.

Ergonomic Back Support

Up to twice as many coils as conventional designs, with up to seven ergonomic zones, deliver targeted spinal alignment and reinforced edge support. Avocado manufactures every coil in-house using recycled steel.

Breathable organic cotton, moisture-wicking wool, and open-air latex promote airflow through every layer. The recycled-steel coil system adds ventilation that conventional foam mattresses can't match — for cool, dry sleep all night long.

Why Avocado?

Avocado was founded on a simple idea — a mattress should be safe enough to sleep on for a third of your life. Every model in the lineup is built to the same organic standard, in the same California factory, with the same certified materials. No exceptions, no separate "premium" line for the people willing to pay more.

Certified Organic, Not Just "Natural"
Certified Organic, Not Just "Natural"

Every Avocado mattress holds GOTS finished-product certification — the standard for fully certified organic mattresses, not just one material inside it.

Q&A answers generated with AI assistance.

Is this mattress supportive enough for big and tall sleepers?

Absolutely. This mattress is specifically engineered for big and tall individuals, plus-size sleepers, and athletes who require superior structural integrity. It features up to 2,112 individually wrapped heavy-duty coils and GOLS organic certified latex, providing a buoyant, responsive support system that prevents the "bottoming out" feeling common in standard mattresses. The extra-firm profile is purpose-built to maintain spinal alignment under higher weight capacities.


Will this mattress maintain its firmness over time?

Yes. The longevity of this mattress is rooted in its high-density construction, featuring over 2,000 heavy-duty coils and sustainably harvested latex. In the furniture industry, organic latex is recognized as one of the most durable cushioning materials available, resisting the sagging and body impressions that often plague traditional innerspring or soft foam beds. This ensures the "extra firm" feel remains consistent for years of nightly use.


How well does this mattress perform in hot or humid climates?

For shoppers in warmer regions like Florida, Texas, or the Gulf Coast, breathability is a top priority. This hybrid design is optimized for cooling; the organic wool and cotton layers naturally wick moisture away from the body, while the dual coil units promote constant airflow through the core of the mattress. Unlike synthetic memory foams that tend to trap and reflect body heat, these organic materials help regulate temperature effectively even in humid environments.


How does the "head-up only" adjustable base help with specific health issues?

The included RTG Sleep 2900 adjustable base allows you to raise the head of the mattress via a wireless remote. From a wellness perspective, elevating the head is a highly effective way to alleviate symptoms of acid reflux (GERD) and can significantly reduce snoring by keeping the airways more open. It also provides an ergonomic position for those who need to sit up in bed for medical reasons or simply to read comfortably without neck strain.


What kind of sheets are needed for a split king adjustable set?

A split king configuration consists of two separate Twin XL mattresses. To ensure the adjustable bases can move independently without resistance, you will need to use two Twin XL fitted sheets. Many of our customers prefer to use these two fitted sheets paired with a single King-sized flat sheet and a King-sized duvet or comforter on top to maintain a unified look when the bed is not in motion.


What are the benefits of the organic materials used in this mattress?

This mattress utilizes GOLS organic certified latex, organic wool, and organic cotton, completely excluding polyurethane or synthetic foams. Beyond being non-toxic, these natural materials are exceptionally durable. Organic latex is known for its ability to maintain its shape and resilience for significantly longer than petroleum-based foams, while the organic wool acts as a natural fire barrier and moisture-wicking layer for a cleaner sleep environment.
