Is Avocado's Coil System Patented?

Yes. The seven-zone coil core used in Avocado's Green, Luxury, and Vegan mattresses is protected by U.S. Patent No. 11,627,813, granted April 18, 2023. The invention is credited to Avocado's CEO, Vy Nguyen, and assigned to Avocado Green Brands, LLC. It is a utility patent that protects the design and construction of the coil system.

The specifications below describe the 1127 coil unit used in the Green Medium, Plush, and Ultra Plush, the Luxury, and the Vegan mattresses. The Green Firm uses the same patented seven-zone architecture in a different unit — our Model 1049 — with a different coil count.

The patent, titled Multiple Zone Mattress Core Element with Multiple Coil Configurations, describes a coil core divided into distinct support zones, built from coils of more than one wire thickness and more than one height. Support varies by body region rather than remaining uniform across the entire surface.

A key point about how this works: firmness comes from how each coil is built, not from wire thickness alone. A coil's gauge, its height, and its number of turns all shape how firm it feels. That is why two coils made from the same wire gauge can perform very differently depending on their construction.

In the 1127 coil unit, three wire gauges are placed across four distinct coil types. The firmest 14-gauge (0.080", 2.0mm) coils run through the center hip and lumbar zone, where body weight concentrates, and across the head and foot end zones, where the structure works hardest. The two largest zones — shoulders and legs — use 15-gauge (0.071", 1.8mm) coils, identical to the hip coil in height, diameter, and turn count, so wire thickness is the only variable and the shoulder settles into the surface while the hips stay level. Two rows of high-tensile 16-gauge (0.0625", 1.6mm) coils run the full length of both long sides; at 1 5/8", they are the narrowest coil in the unit, and because a narrower coil resists compression more sharply, they hold the edges firmly and resist the permanent set that comes from years of sitting in the same spot. A fourth coil type — also 16-gauge, but wider at 1 7/8" — is nested in every other row throughout the unit rather than assigned to a zone. It is the softest coil in the system, and it blends the firmness change from one zone to the next so transitions are gradual rather than something you feel as an edge. Because the head and foot zones are built identically, the mattress can be rotated head-to-foot so it wears evenly.

The result is a coil core zoned into seven regions: a pair of side zones, a pair of end zones at the head and foot, and three interior support zones for the shoulders, hips, and legs. Support is softer under the shoulders, firmest under the hips and lumbar, and softer again under the legs, with firmer border coils holding the edges on all four sides.

The patented seven-zone coil core is used in the Green (Firm, Medium, Plush, and Ultra Plush), Luxury Organic, Vegan, Wool, and Grand Luxe mattresses. The Green Extra Firm uses a separate two-unit "coil-on-coil" construction and is not part of the patented seven-zone design. The Eco Organic mattress uses a simpler unit built from two gauges (14 and 15), and the Eco Organic Kids mattress uses a single-gauge 14 unit at a lower 6-inch profile. The all-latex Organic Latex Mattress has no coils. For the full per-model coil breakdown, see Coil Count and Innerspring Specifications for Every Avocado Mattress.

Most mattress brands buy their coil units from a small number of third-party suppliers. Avocado designs and manufactures its own innerspring units at its directly operated Tecate facility, from recycled steel wire through the finished zoned unit. Owning the process makes it possible to control the gauge, height, and placement of every coil, rather than relying on a supplier's catalog.

Each coil floats independently inside food-grade, non-woven polypropylene fabric, and the innerspring unit is included in the finished-product certifications the mattress carries: GOTS, OEKO-TEX® Standard 100 Class I, MADE SAFE®, EWG Verified®, GREENGUARD Gold, and UL® Formaldehyde-Free.

No. The patented seven-zone core is used in the Green (Medium, Plush, Ultra Plush, and Firm), Luxury, and Vegan mattresses. The Green Extra Firm uses a different coil-on-coil construction, the Eco uses a simpler coil unit, and the all-latex Organic Latex Mattress has no coils at all.

The coil core is zoned into seven regions: a pair of side zones, a pair of end zones at the head and foot, and three interior support zones for the shoulders, hips, and legs. In the 1127 unit, this is built from three wire gauges across four coil types — 14-gauge under the hips and lumbar and at the head and foot ends, 15-gauge through the shoulder and leg zones, and high-tensile 16-gauge along both long sides. Firmness is set by how each coil is built — wire diameter, coil diameter, turn count, and preload together — not by wire thickness alone.
