"Benefits of ergonomic chairs depends on if its a chair that is just labelled "ergonomic" or if it is a real ergonomic chair.When ergonomics became popular manufacturers started calling any chair which they designed for working at a computer as "ergonomic", kind of like calling anything green or environmentally sustainable because they thought about the environment, but didn't really change anything because there was no real research as to what to do.Chairs that are labelled "ergonomic" range from being not ergonomic and actually harmful to somewhat beneficial or better than a poke in the eye with a sharp stick. For example common ergonomic chairs are mostly designed to look cool and may give you some lower back support and reduce pressure points. In the the case of mesh chairs they also dissipate heat and moisture which can be a source of discomfort. Fun fact, the Aeron chair was designed with mesh because a study had come out prior to it's design showing most discomfort and fidgeting was caused not by pressure points as much as by heat and moisture buildup. Problem is the hard frame causes a host of other problems and their are better solutions.Benefits of a real ergonomic chair include important benefits like helping prevent repetitive strain injuries, sciatica, herniated disks, headaches, reduced blood flow, etc. Real ergonomic chair designs, like the Soma Chairs pictured below, can provide these benefits because they include features clinically proven to do so, plus unexpected benefits like lower heart rate, deeper stress reducing breathing, more blood to the brain and arms, improved digestive organ function, prevent metabolic shutdown syndrome, and more. Here are a couple of examples of chairs that offer those benefits.An additional important insight from 30 years of experience is that to get the highest benefits the person often needs to be trained on how to hold their posture and muscles differently and adjust and use the chair to properly position and stabilize that more healthy posture. In other words you can have the best equipment and still not get optimal benefits if you use it wrong. So a complete ergonomic solution includes behavioral body posture and use training to get the highest amount of benefits. A tool like the Cricket Wearable Sensor is excellent for that.
