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 is also a seven-zone mattress but uses a different coil unit.

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 work together to zone support by body region. The center hip and lumbar zone uses the firmest coils, 14-gauge (0.080", 2.0mm), to support the heaviest part of the body and help keep the spine level. Transition rows of 15-gauge (0.071", 1.8mm) coils ease the change in firmness so it is gradual rather than abrupt. And 16-gauge (0.0625", 1.6mm) coils are used in two roles: softer coils through the head and shoulder zone that let the shoulders sink for pressure relief, and firmer border coils around the perimeter. 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 (Medium, Plush, Ultra Plush, and Firm), Luxury, and Vegan mattresses. The three-gauge 1127 unit described above is used in the Green Medium, Plush, and Ultra Plush, the Luxury, and the Vegan; the Green Firm is also seven-zone but uses a different coil configuration. The Green Extra Firm uses a separate two-unit "coil-on-coil" construction and is not part of the patented seven-zone design, and the Eco mattress uses a simpler coil unit built from two gauges (14 and 15). 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.

The inventor of record is Vy Nguyen, Avocado's CEO.

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, placing the firmest coils (14-gauge) under the hips and lumbar for support, softer coils under the shoulders for pressure relief, and firmer border coils around all four sides. Firmness is set by how each coil is built, not by wire thickness alone.
