You have to spend a lot of time in your office chair, so take the time to make sure you’re sitting pretty. Before you take a seat, ask yourself:

1. Is it adjustable?

An adjustable chair means you can comfortably change positions to suit what you’re doing—typing, talking on the phone or dreaming up your next big idea.

2. Does it offer back support?

You don’t want to have to go to a chiropractor after a hard day at work. Buy a chair that supports your back, and you’ll be able to walk out of the office at the end of the day with your head held high.

3. Does it promote good posture?

While there’s no need to strike a ballerina’s pose, sitting up straight keeps your back from hurting late in the afternoon.

4. Can you move around in it?

Make sure your chair rolls and swivels easily, without wobbling or rocking, so you can quickly grab hard-to-reach files.

5. Is it comfortable?

While it probably isn’t a good idea to get this comfortable, make sure your office chair will stay comfy throughout the day before you buy.

Give your chair a thorough test run—ask if you can test-sit in it for a day before buying it. You’ll be happier and more productive—and so will your associates.
