What is the value of an adjustable back angle on an ergonomic chair?

An adjustable backrest angle lets you recline to 110°–120° for reading and reviewing documents, then return to 100°–105° for active keyboard work — reducing the static loading that comes from holding one position all day. Fixed-back chairs lock you into one angle that fits some users and tasks well but not others. The ability to shift your backrest angle throughout the day reduces muscle fatigue in the spinal extensors by up to 25% compared to a fixed-back position.
