Most office chairs fail in one of three ways: the foam packs down and stops supporting you within a year, the gas cylinder sinks so the seat won't hold its height, or the mesh sags out of shape. We engineered against those three. Every chair is built to 100,000 load cycles — the seat, the tilt mechanism, and the gas lift tested together, not one part in isolation — on a reinforced aluminium 5-star base, not nylon. The CAD for the ErgoChair Ultra 2 is open source on GitHub, and the work behind the backrest is documented in our ergonomics research. You can read the design instead of trusting a spec sheet. A mesh office chair lives or dies on the back — ours vents heat over a long session and holds its shape over years of daily use.
People who sit for the long stretch — long work sessions, deep work, building, writing, coding. A desk chair has to hold up over hours, not minutes, so the design is built for the eighth hour: synchro-tilt that moves with you, 3D or 4D armrests that get out of the way, a seat that relieves pressure instead of trapping heat. If you're up and around all day, a simpler task chair is fine — this one is for the people who stay in the seat. Pair it with a standing desk if you want to break the sit, too.
Three questions settle most of it. How your back wants support — the ErgoChair Ultra 2 is lumbarless, its exoskeleton frame flexes to hold the whole spine; the ErgoChair Pro has a lumbar pad you slide to the exact spot. How tall and heavy — the Pro fits up to 6'3" and rates to 300 lbs, the Ultra 2 Plus takes up to 330. How long it needs to last — the frame warranty runs from 2 years on Core to lifetime on Ultra 2 and Pro. Sit in it for 30 days at your real desk; if your back doesn't agree, send it back. The comparison page lays the specs out side by side.
Three rough tiers in the office chair market. Big-box chairs under $200 use thin foam and nylon bases that give out in a year. Premium ergonomic brands at $1,000–$1,800 — the engineering is real, but a chunk of the price is the name on the back. Autonomous holds the engineering bar from the $279 Core to the $499 Ultra 2 Plus. What we don't do: hide the spec sheet, ship a nylon base, charge for the brand. What we do: publish the recline range, the cycle count, and the weight rating.

The back. Ultra 2 is lumbarless — the exoskeleton frame supports the whole spine. Pro has an adjustable lumbar pad you slide to your preferred spot. Italian tilt, mesh back, aluminium base, lifetime warranty — same on both.
