If you spend most of your day working at a desk, then you know just how important it is to have a comfortable, supportive desk chair. Furthermore, if your current chair just isn't cutting it anymore, you might be interested in shopping for a new one. Before you pick out just any new office furniture, however, there are some things to keep in mind.

Specifically, you'll want to avoid some common mistakes people make when selecting a new office chair:

Not Considering Circulation

First and foremost, you'll need to make sure that the chair you end up choosing sits you in a position that promotes blood circulation throughout your body. With many desk chairs, you simply aren't getting the proper blood flow that you need.

The best way to find a chair that will promote healthy blood flow is to choose one where--when sitting--you're positioned with your knees slightly bent, your feet flat on the floor, and your lower back against the back of the chair. Any chair where your feet are too close to the floor or aren't touching the ground should be overlooked.

Overlooking Arm Support

Another mistakes to avoid when shopping for a new office chair is buying one that doesn't come with arm support or arm rests. You might not think these are a big deal, but the fact remains that proper arm support can actually help to improve your overall posture while making your sitting position more comfortable.

As a result, you'll be able to work for longer periods of time without discomfort. Specifically, you'll have the support your elbows need when you're typing at your computer keyboard.

Lack of Adjustments

No matter which office chair you end up going with, one of the most important features to look for is the ability to make adjustments as needed. A chair that claims to be "one size fits all" should be immediately overlooked, as there's no way such a chair is going to provide the support your body needs.

Ideally, the chair's height should be completely adjustable so you can ensure your feet just properly touch the ground. Furthermore, adjustable arm rests and an adjustable head rest (for taller people) is an added bonus you may want to look for as you shop for your next office chair.

By avoiding these common mistakes when shopping for your next office chair, you'll be well on your way to making the right decision.
