People often spend long hours in an office chair, which can put stress on the spine.
In order to prevent back problems and fatigue, it's prudent to have an ergonomic chair with support for the lower back while promoting good posture.
This is important because when employees experience fatigue early in their day due to poor posture, work productivity decreases.
This will affect the overall business.
There are many different types of ergonomic chairs for the office and also a lot of various things which are important to look for in a chair.
These features allow the users to adjust the chair based on their needs.

• A height adjustable seat is an important feature.
  People come in different heights, so look for chairs that have a lever under them for height adjustment.
  Typically, sixteen to twenty-one inches is the rule for height, which should place the workers feet flat on the floor at all times.
  The thighs have to be parallel to the floor, and their arms should rest comfortably on their desks.
  
• The seat in the chair should have adequate width and depth to comfortably support almost any person.
  The standard is usually twelve to twenty inches wide which allows the user to sit with their back against the chair.
  This should leave 2-4 inches between the back of the knees and the chair.
  There should also be an adjustment for tilting the seat forward or backward.
  
• The lumbar adjustment gives support to your lower back and is a very important feature.
  It is in the lower back where most people have trouble, and the correct seat will help address this and prevent future damage.
  It is also important to make sure that a chair doesn't cause the user to slouch.
  This posture will place strain on the lower spine.
  
• The fabric or material on the seat and back should be padded enough to allow the users to sit for extended periods.
  Soft breathable fabric is preferable to a hard surface.
  Conventional chairs should rotate so the user can comfortably reach any area of their workspace.
  This allows the worker to be efficient in their tasks, not wasting more time attempting to reach something within their work area.
  

A chair that has been designed well allows the user to be balanced.
When the chair and the user are balanced, the chair almost goes unnoticed by the person sitting in it.
It becomes a seamless part of their work area.
Purchasing an ergonomic chair is a good start, but the benefits are limited to the user and their habits.
It's up to the user to make sure to practice sitting properly.
When the user practices good posture, the chair can be an added benefit to the office work place.
