The answer isn’t quite straightforward here. Obviously, if you’ve got a chair that’s broken or no longer provides good support, there’s no better time than now to replace it – hopefully with a better option. But if you’ve got a working chair that has no massive issues, chair manufacturers somewhat disagree on when you should replace yours. And, that’s really due to the fact that it largely depends on their build. Some crafted for home and office will last you seven to eight years, others will last you five. A handful, like the Humanscale Freedom, will last you 15 or more years. Of course, factors like the level and amount of usage, as well as environmental conditions, matter as well. We recommend consulting your chair’s manufacturer first before dropping another $150/£150 to $2,000/£2,000 on a new chair. And also, trust your gut. You’ll know when your trusty old chair just isn’t cutting it anymore.
