What is a posture chair and how does it differ from an ergonomic chair?

"Posture chair" is a marketing term without a standardized definition — it's often applied to chairs with a forward-tilted seat that encourages an upright lumbar curve. True ergonomic chairs are defined by adjustability across multiple parameters (seat height, depth, lumbar, armrests, tilt) rather than any fixed design feature. A posture chair with fixed settings might benefit some users and harm others; a proper ergonomic chair adjusts to fit many different users. Be skeptical of "posture chair" claims without specific adjustment specs. FindOfficeFurniture.com has genuinely adjustable ergonomic office chairs — call 888-719-4960.
