HR - Benefits - Ergonomics - Chair Guide
Check out this guide to learn the 4 most essential features of any ergonomic office chair.
Height-Adjustable: One of the most basic features to look for is height-adjustability. Standard chairs are about 18" off the ground which is great if you're about 5'6". However, if you're much taller thank this you'll end up over flexing your hips which will put pressure on the hips and lumbar spine. If you're shorter, your feet may not reach the floor and as a result you'll end up perched at the edge of your seat, leaning forward and straining your back.
Height-Adjustable Lumbar: The natural curves of the spine are what give our backs strength and flexibility. A height-adjustable lumbar support ensures that you're getting the right support exactly where you need it to prevent a slumped posture.
Backrest Recline: Alternating throughout the day between sitting upright and reclining is one of the best ways to care for your back while seated. Try alternating between an upright posture and a 110-120 degree recline against the back support. This will help reduce pressure on the spinal discs, and limit overuse of the your back muscles.
No Arms: It's better to go without arms than to have arms that don't adjust low enough. Arms that do not adjust low enough will hit the edge of your desk, preventing you from tucking in fully and causing you to lean forward as a result. This is a major cause of low back strain and discomfort amongst computer users.
