We know this goes without saying, but a good office chair, the best office chair, will offer proper ergonomics to appropriately support your back and body for long periods of sitting. While no chair can negate hip and lower back issues, the best alleviates some of the pain one experiences from sitting for longer periods of time.
Also take note of your hip positioning when considering a good office chair. While adjustability relates to an office chair’s ergonomics, it’s also a big enough factor to stand alone. Therefore, you should be able to influence a chairs lumbar support, and you want to also be able to manipulate it enough to suit your particular body type.
Besides, height adjustability is a good factor to consider, as we’re not all built equally, and nor are our desks. The arms should be adjustable as well as the angle of the back.
