Repairing a Pneumatic Chair?

November 4, 2020

I have an air lift saddle stool that will not stay down! The minute I stand up, the seat rises all the way! It's exactly the opposite of everyone else's problem! I can't find that issue anywhere for advice! Can someone help?

It appears that some of the issues with these chairs deal with the screws that are holding the chair in place. One suggestion was to take all the screws off the seat, arms, and back of the chair. They said to use a screwdriver or even a socket wrench to do this with. Once off they said to use a strong adhesive on the threads of all the screws and allow this to dry. Now once dried put them back in place. I have seen the repair suggestion for the sunken seat you are talking about and what they suggest that you do. However, this is not your problem. Your problem seems to be the opposite to this one. In your case, I am wondering if the screws are not holding the seat in the lower position and allow it to go up.

In adjustable chairs, there are several levels that are used to adjust the chairs. It sounds like your friend has fiddled around with some of these and has either stripped the screws or broken a part that is necessary to adjust the chair correctly. They do offer a few replacement parts online that you can buy to see if you can fix this issue. Some of the parts seem rather expensive and would almost be better to buy a new chair than to fix it. I would try fixing the screws first to see if this one helps then buying one or two replacement parts to see if you can get the chair working again.

You are stating an 'air lift saddle stool' and the Pneumatic system may work the same as in the chair, but, just in case; be sure whoever you talk to knows what type of stool/chair you're talking about.

I'm not familiar with this system but it does not sound like you need a new gas cylinder which means you will probably have to take it apart to do any repairs.
I believe that when you loaned your chair out it was probably either twisted or possibly raised high and picked up by the seat while in that position which could have pulled something loose or thrown it out of adjustment.
I did find a YouTube video that might help - check it out because it seems to be very clear.

I did find that most people just want to toss a chair when they start having problems.
One solution seems to be to set the chair in the position you like and then fix it so it just stays and will not adjust to another height. I do not think your chair is to that point.

I'm including this link because some people do have the chairs and this 'saver kit' is what a lot of forums are recommending. If you decide to go this route you would need to contact the company to make sure it would work on your stool. Note: I know absolutely nothing about this company.

This is a 'do it yourself fix' for an office chair pneumatic gas lift cylinder repair idea from one of the fix-it forums.

If you cannot find a way to do the repairs yourself, you might consider taking your stool to the Sears Service Center to see if they can help you (if they are open in your area).
Sometimes they will just look at it in their shop to see what parts you might need and just fix it on the spot. You can ask what the charge will be and decide at that time. Sears shops usually can make repairs to any brand and I'm sure they are familiar with pneumatic chairs/stools.

My computer chair won't stay up. It goes down with the lever, but not back up when I sit in it. When I turn it on its side and put it up, I sit down and it goes down. Help.

I used an Office Chair Buddy to fix my sinking desk chair. I'm pretty handy, but didn't want to waste time replacing the cylinder. This Office Chair Buddy literally fixed my issue in just a couple of minutes (and that included me opening the package....haha). Got it on Amazon for around $20-$25

The chair raises and lowers by air pressure (I think) or hydraulic (less likely) when a handle is pressed. It fails to remain in the "up" position and sinks to the lowest position when the seat is occupied. Is it repairable ? If so how (manufacturer is unknown)?

Thanx.

Might be there is some mechanical problem in the chair. To get it repaired in a better way, you must contact some expert manufacturer and get it done easily. As experts have years of experience in repairing the chair, they can help you in a better way.

You need to replace the cylinder that lets the chair go up and down. Replacement cylinders are available from the manufacturer or eBay. Here is a how-to article. www.ebay.com/.../g.html
