Removed from practical experience or reality; referring to someone who offers opinions or criticism without direct involvement or expertise, from the comfort of sitting in an armchair.
From armchair (a chair with armrests) plus the suffix -ed. The term 'armchair' became metaphorical for sitting at home making judgments about things you're not directly involved in, popularized through phrases like 'armchair quarterback.'
The word 'armchaired' reveals how furniture became a metaphor for privilege and distance—only wealthy people could afford to sit in comfortable chairs while others worked, so sitting in an armchair while criticizing someone actually doing the work became an insult about perspective.
