Our own factory · Vertically integrated

No middlemen, so nothing gets value-engineered out

Tooling, injection molding, mesh tensioning and final assembly happen on our own line. Chairs built to this standard usually pass through several hands before they reach a showroom, and the price carries every one of them.

High-tension one-piece mesh
Tension rated through 30,000 rebound cycles — it does not sag over time.
Class 4 certified gas cylinder
The highest safety class. Free replacement for five years if it loses pressure.
Silent nylon casters
Won't mark hardwood; rolling noise measured below 35 dB.

Every chair is validated by third-party testing

Independently tested and certified — not self-assessed.

Certified
BIFMA X5.1

Passed 120,000 seat-cycle fatigue tests and a 300 lb static load test.

Certified
Greenguard Gold

Low VOC emissions — meets indoor air quality standards for schools and healthcare settings.

Certified
OEKO-TEX 100

Mesh and textiles are free of harmful substances and safe for prolonged skin contact.

Compliant
CA Prop 65

Compliant with California Proposition 65 chemical disclosure requirements.
