Contact ChairKey

ChairKey is a small, independent, ad-supported site — there is no support team standing by, but a real person reads what comes in to support@chairkey.com.

A few things this address is genuinely useful for: a calculator that gave you a result you think is wrong (say which tool — the seat height calculator, desk height calculator, monitor distance calculator, chair weight capacity checker, sit-stand calculator, or posture angle checker— and what you entered); a tool or topic you wish existed on the site; an out-of-date fact or broken link in the blog, learn section, or the Wonders & Destinations Museum; or a bug in how a page looks or behaves on your device.

There’s no fixed response time to promise, and no ticket number or live chat — email is read and handled as it comes in. If a question is really about a persistent pain, an injury, or a medical condition, a doctor or occupational therapist will have a more authoritative answer than this site can give; ChairKey’s tools produce general estimates, not medical determinations, and the site isn’t affiliated with any chair manufacturer or furniture retailer.

Before writing in about a tool result, it can help to double-check the numbers you entered — height, weight, or measurements are the most common source of a surprising answer. If it still looks wrong after that, that’s exactly the kind of message worth sending.
