Diagnose Your Chair Problems

Diagnose Your Chair Problems

After going through different ergonomic chairs, the multiple parts of three very popular chairs and what they all do – it’s time to diagnose what might be wrong with your chair and how to fix it. Overall, chairs should not be very difficult to fix, but for the purpose of this post, we will only be focusing on office chairs. 

Let’s look at some of the most asked questions when it comes to office chairs. 

1. Can I still use my chair if it has a broken component?

Broken chair components happen to all office chairs. It is important to the manufacturer that a chair is working with all of its components. However, sometimes they break. If the chair has arrived with a broken chair component then contact the manufacturer immediately to inform them of the issue. Otherwise, have a look at the damage yourself if you have broken your chair. The best advice is to use a chair that is working just right, so you don’t hurt yourself. 

2. My office chair is hurting my back, why is that?

Well, this can be a sign of many things, but one of the first things to think about is the lumbar support. When your chair has poor lumbar support, you are more likely to have back pain. This can also happen if the armrests are too high or too low because this will affect your shoulders. Backs tend to hurt when an office chair that is not ergonomic is being used because they’re not designed to help relieve the tension from your body while you’re working. Take some time to read the manual of the chair, so it can be used to its fullest potential. Otherwise, look at buying an ergonomic chair, like the ones at the beginning of this post. 

3. One of the wheels on my chair broke, what do I do now?

One of the wheels on my chair broke, what do I do now

This is a good question because the wheels on a chair move around a lot on the ground. Most of the time, if it snags onto a piece of rug or a wire, it can be easily removed from the wheel and stay intact. However, there are times when the wheel can break, whether it is from pulling a foreign object out of the wheel with too much force or it has fallen over awkwardly. If this happens then you may be able to repair your wheel yourself. By doing this, you will save money by not buying a new chair. Read the manual to see if there is advice on how to fix your wheel. Otherwise, look on the internet. Also, check out our post on wheel replacement for office chairs for more advice. 

4. I want to change the base of my chair. Can I do that?

Of course! Many people change the base of their chairs from one with wheels to one without because of the increase in productivity when it comes to their work. Also, it can help save your floors. We have a post that talks about replacing the base of your office chair. It will break down the different bases and the benefits of them, while explaining how to change the base of the chair yourself. Bases of chairs need to be changed and that’s quite normal, whether it’s a style preference or because it’s broken – there is a base that is just right for you. 


Chairs are a lot more complicated than people realize and they are used all the time. It’s important to know the different parts of chairs and how to fix them when they break. Having this knowledge can impact your decision on which ergonomic chair to buy for yourself when it comes to your home office. Remember, pick a chair that best supports you mentally and physically.
