Bar stools are very popular in bars, restaurants, and homes, and they can be quite expensive. A hydraulic bar stool consists of the stool itself, which is usually made from metal or plastic, and a hydraulic system that allows the user to adjust the height of the stool. If your bar stool is not working properly, it can be frustrating and annoying. Fortunately, fixing a hydraulic bar stool is relatively easy, and in this article, we will discuss how to fix a hydraulic bar stool.

Determine the Problem

Before you start to fix your hydraulic bar stool, you need to determine what the problem is. The most common problem with hydraulic bar stools is that they will not stay at a certain height. This is usually caused by a leak in the hydraulic system. To determine if your bar stool is leaking, remove any decorations at the base of the stool and try to raise it up. If the stool goes down by itself, then it is definitely leaking. Another common problem is that the stool will not raise up or go down after you press the lever. This is usually due to air trapped in the hydraulic system. To release the air, you will need to bleed the hydraulic system.

Fixing a Leaking Hydraulic Bar Stool

To fix a leaking hydraulic bar stool, you will need to remove the seat from the base. This is usually done by unscrewing it. Once you have done this, check the hydraulic cylinder for any visible cracks or damage. If the cylinder is damaged, it will need to be replaced. If the cylinder looks ok, then check the seals for any damage or dirt. If they are damaged, replace them. If they are dirty, clean them with a cloth. Reassemble the hydraulic bar stool, and the leak should be fixed.

Fixing the Hydraulic Bar Stool That Won't Raise or Lower

To fix a hydraulic bar stool that won't raise or lower, you will need to bleed the hydraulic system. Bleeding the system releases any air that may be trapped in it. To do this, remove the seat from the base of the stool. Locate the bleeder valve and open it using a crescent wrench. Then, turn the lever to raise or lower the stool. As the air releases, oil will come out of the valve. Keep going until only oil comes out. Once this is completed, tighten the bleeder valve and reassemble the stool. It should now work properly.


In conclusion, fixing a hydraulic bar stool is relatively easy. The most important thing is to determine the problem first. Once you know what the problem is, you can proceed with fixing it. Whether it's a leak in the hydraulic system or trapped air, there is a solution. The key is to take your time and follow the steps carefully. With a little bit of patience and know-how, you can save money by fixing your hydraulic bar stool and avoid having to buy a new one.
