I am sorry if my description is not clear enough. You know there are certain office chairs (unless the wooden chairs or steel folded chair) whose back can bend backwards when you lean against them. Is there a special term for this feature? How to call such chairs?
A recliner generally refers to an armchair (or sofa or couch) that can recline, and often has a footrest that lifts up as the back goes back.
However, a reclining office chair is an office chair that allows the person sitting in it to lean back, and have the backrest lean back with them.
These are generally high end office chairs, and may be called executive chairs, but not all executive chairs have that feature.
