Is a ergonomic office chair patented?

Short answer: specific designs of a ergonomic office chair have been patented many times, but "a ergonomic office chair" as a general idea is not what is protected. What matters is the exact combination of features in your version.

What our index shows
  • 296 US and WO patent publications since 2000 have a title matching “officedeskergonomic chair” or a close variant (our index of 9.7 million patent families; one publication per family).
  • Among the 282 best keyword matches we examined, 59 were published in 2020 or later, and the earliest was published in 2000.
  • Most frequent assignees in those matches: BOCK 1 GMBH & CO KG (18), SANDER ARMIN (10), HAWORTH INC (9), IMARC SPA (6).
  • Most common patent classes (CPC subclasses): A47C (274), B60N (10), A63B (9), A61G (9).

Counts come from keyword matching on titles and abstracts, so they are indicative, not a legal count. Some matches are different products that share a word.

What this means for your idea

Because patents cover specific combinations of features, the useful question is not “has a ergonomic office chair been patented?” but “has my combination of features been described before?” Tools and office products differ in grips, adjustment mechanisms, and how blades or bits are held and changed.
