How to Fix an Office Chair that Won’t Stay up Quickly?

Before you go ahead and get to know how to fix an office chair that won’t stay up, it’s important to know about the mechanism of these chairs. Normally these chairs use pneumatic cylinders which control the chair height using pressurized air. The pneumatic cylinders provide the support system for the chairs to stay at a fixed height using the suspension mechanism. This type of system normally consists of a valve as well which makes sure that the chair rises or sinks according to your requirement. So, now that you have a faulty chair at your disposal, let’s start and see if you can fix this using the DIY methods.

1. Using a hose Clamp: 

Before you proceed with this repairing method, keep in mind that you won’t be able to adjust the height of your chair afterward. Okay, since you have made up your mind, let’s start with the process right away:

Step 1: In most cases, you will find a plastic tube surrounding your metal cylinder. So, before you can proceed, you need to slide up or down this plastic tube and find the pneumatic cylinder underneath.

Step 2: As you know, once you fix your chair, there is no way you will be able to adjust the height. So, you need to choose your preferred height at which you want to fix your chair. In case the chair isn’t staying up even when nobody is sitting on it, you have to lay it sidewise. You might need to remove the plastic skirt that covers the cylinder.

Step 3: you need to buy a hose clamp. Find the screw on the hose clamp and loosen it. Pull the belt end out. Wrap the cylinder using the clamp carefully and tighten it but do not try and overdo it.

Step 4: to make sure that the chair remains at the fixed height that you require, make sure that the clamp is tight enough to hold the chair seat up. To do so, you can either use a strip of rubber or duct tape to wrap the cylinder. Doing so, the clamp will have a better surface to hold the chair up for longer durations.

Step 5: Before you use the screw on the hose clamp to tighten it, double-check that the height of your chair is fine. Once you feel that the arrangements are simple yet comfortable for you then you can tighten the screw.

Step 6: once you are done with this, try and sit on the chair and check whether the clamp slides down or not. If the chair keeps on malfunctioning you need to try the other method and see if that works properly or not.

2. Using PVC pipes:

Step 1: The first thing is to measure the cylinder diameter. To do so, you need to remove the plastic skirt and use a ruler horizontally. Remember to measure the cylinder length as well. Make sure the chair is at the required height before you measure the cylinder length.

Step 2: Now you have to buy a PVC pipe. While buying the PVC pipe, make sure that the pipe diameter is slightly larger than the cylinder. Buy straight pipes of proper height so that it fits in the gap properly and maintain the height. You can use small pipe pieces or you can use a single piece of pipe to fix your chair.

Step 3: Remember to use a hacksaw to do the cutting work. Cut through the pipe lengthwise from tip or tip but you need to slit the pipe in only one side of it. In case you do not have a saw to cut the pipe, you can just remove the while base and then slid the pipe up to adjust the height of the seat.

Step 4: Now you need to fit the pipe on the cylinder. To do so, you have to first pull the plastic skirt up or down. Once the metal cylinder is out, snap it around the cylinder. Your seat should be at your required height now and the pipe around the cylinder will ensure that it does not sink at all.

Step 5: Remember to use smaller pieces of pipes to fill the gap properly and cover the cylinder. In case the chair height is not what you want, you can add another piece of pipe to increase the chair height a bit more.
