But chair companies and ergonomists often throw around terms related to the designs and functions of ergonomic chairs that the common consumer may not understand. Here is a list of some terms you may need to know.
Lumbar Support: This is one of the most important features of an ergonomic chair. This device is intended to prevent, as much as possible, the flattening of the lumbar spine that occurs to most people when there are seated. Lumbar supports usually work as a gentle curve in the backrest shape, and allow user to be seated more comfortable for a longer period of time.
Backrest Height Adjustability: This function allows the user to change the height of the lumbar support area in the chair backrest, although this feature is often interpreted as the ability to change the height of the entire backrest. This function accommodates preference by different users regarding where and how the lumbar support curve contacts the back.
Lumbar Depth Adjustability: This feature affects the size and sometimes the firmness of the lumbar support curve in a chair’s backrest. Like backrest height adjustability, it accommodates different body types and preferences by the user.
Height-adjustable Armrests: This function, as the name suggests, allows the user to adjust the height of the armrests to suit the body of the person, this helps people avoid using chairs with too high or too low of armrests, which could result in elevated shoulders and pressure on the undersides of the elbows and forearms, or would require the user to slump or lean over to one side to use the armrest, respectively. This feature also allows for the armrest to be moved out of the way during some activities that may require lots of arm movement.
Width-adjustable Armrests: This function allows the user to change the distance between the armrests, not the armrests themselves. For an ergonomic office experience, the user does not want a chair with armrest too close together as this will splay the elbows and cause the wrists to bend to the side during activities such as typing. This puts the user at wrist for Carpal Tunnel Syndrome.
