When you are shopping for office chairs, you have to think about price, comfort, and ergonomics all at the same time. You likely have a budget that you have to stick to, but you don't want to buy chairs that no one can sit in either. There are standard features that most office chairs come with, which you should look for when doing your shopping. These features can really add to your comfort when sitting in the chairs, and should be considered a necessity.
To me, one of the most important features that every good office chair should have is an adjustable back rest. Since no two people are built the same way, this can really help make certain that whoever sits in the chair is comfortable and ready to work. You should be able to adjust the height of the backrest so that your lower back is fully supported, and the back of the chair should also tilt as well, so that you can find and set your most comfortable position. To make certain that the chairs you purchase can accommodate the needs of everyone in the office, you should also look for one that has a backrest that can be widened and tightened as needed.Another feature on your office chairs that you shouldn't do without is the ability to raise and lower the height of the chair as needed. It should be easily adjustable, so that with the push of a button you can raise or lower the chair to a more ergonomic position. Your feet should comfortably rest flat on the floor, and if they can't reach, then you need to lower the height of the chair. This feature can help prevent back strain and injury associated with sitting for long periods of time.
You also want to look at the seat of the chair, starting with the edge of the cushion. You want it to be rounded, so that it doesn't create pressure points on the legs, especially after long periods of time. A seat that can tilt is also a good idea, which can help make sure that everyone who sits in it is comfortable. You want to make certain that the chair is covered in a durable fabric that is easy to clean, and one that won't hold or attract heat.
Your office chair should have armrests, and they should be adjustable for optimum use. You also want to make certain that they are padded, which will make them more comfortable while in use.
Last but certainly not least, you want to think about safety when purchasing your office chair. You want to chose a chair that can support weight adequately, and that looks like it can hold up to a lot of use.
