If you spend hours at your office, you probably know how important a good chair with back support is. The ergonomic chair is specifically designed to help you maintain the right posture for long working hours, which improves blood circulation, relieves strain on the back and helps you remain productive and comfortable throughout the day.
1. Lumbar Support
It’s very important for an ergonomic chair to have lower back support. 
The lumbar spine comes with an inward curve. This curve plays a crucial role in maintaining your lower spine and your natural curve. A good chair for office use should contain a lumbar adjustment (both depth and height) so you can get the appropriate fit to support the inward curve of your lower back.
The seat height of a good office chair should be easily adjustable to fit each user. This means that it should have a pneumatic adjustment lever. Most people prefer a seat height with an average of 16″ – 21″ off the floor. This allows you to have your feet flat on the floor, and with your thighs horizontal.
The backrest of a good chair with back support for office use should be 12” to 19” wide. This part of the chair is separate from the seat, and then it should be adjustable in angle and height. It should also provide support to the natural curve of your spine. If the chair has the backrest and seat together as just one piece, then its backrest should be easily adjustable in back and forward angles.
The seat of a good office chair should have enough depth and width to support anyone using it comfortably. In most cases, 17” to 20” wide is the standard, and the depth needs to be sufficient so that you can sit with your back against the backrest of your chair while leaving approx. 2” to 4” between the chair’s seat and the back of the knees. The backward and forward tilt of the seat should also be adjustable.
5. Seat MaterialThe material on the ergonomic chair back and seat should have enough padding to make you comfortable for long working hours. It’s recommended to choose a chair that has a cloth fabric on the seat and back.
Conclusively, while arm supports are sometimes useful on an ergonomic chair, choosing one without arms can be preferable, particularly if you have an active job. Arm supports may be good if you frequently move around to take care of various tasks around the office. Always consider these factors when looking for a good chair with back support.…
