How can I fix the hydraulic lift on my computer chair - without having to lose weight?
Posted by: Jerry®
Date: July 30, 2011 11:21AM
It has started to slip and I slowly end up with my chin in line with my desktop. Anyone handy enough to know if there's some sort of thing I can tighten....or??

thanks

Usually the lift cylinders are sealed units, nothing to be tightened, etc. Once the internal valve starts leaking not much you can do but replace the cylinder. Better chairs the part is available as a replacement item, cheap chairs you just buy another chair. So if you have something like a Steelcase or Herman Miller chair, contact them for repair parts.

Well it's most likely a cheap chair. I got it at WalMart for $150 - not cheap to me but still.....

$150? - a midrange chair. Parts might be available, but you most likely will have to pay for them. That is if you can find the manufacturer. Higher end chairs you might get the part for free as many have lifetime or long term warranties.

Isn't that what cinderblocks are for?

Replacement cylinders:

Replacing a gas cylinder:

I get my office chairs from office supply stores when they have sales and stackable coupons at prices so low they're practically disposable. If a replacement cost $150 bucks, I'd probably try to repair the chair before replacing it.

I've found that the cheapo chairs pretty much have the same cylinder assemblies. I've saved a few chairs over the years and have cobbled together parts to extend the life of seemingly "trashed" chairs.

Maybe keep an eye out for parts on trash day?

This is a great and funny post ~!~ First of all I want to offer that a lot of the chairs presented to us are made in China. They are sheet ~!~ I currently have 3 in my Apartment. 2 broken and """won"""" still functional. Daves idea is perfect. We need more cinder blocks.

Another thread is why do we keep buying such crap from China.

I hear you Jerry. Fortunately as I am laughing my current chair is maintaining its limited integrity *(:>*

Just as a scientific suggestion and for the sake of research why not try some helium enemas and lighten your loaf tongue sticking out smileygrinning smiley cartman smiley devil smiley jest smiley

Up to a certain price point they all have the same crappy hydraulic units.
If you have any experience drilling steel (or a friend with a drill press) I would seriously consider drilling it out at the height you want and sticking a bolt in it-- done.

Going along with Black's thought of drilling through the cylinder, you might be able to put a c-clamp around the tubing so it can't drop down. I've done this on a hydraulic-operated kitchen stool. Easier than drilling. This is with the assumption you want to keep the chair at one specific level. Post a pic and maybe we can throw out some other ideas.

I had the same problem and one day I got lucky…

… one of my neighbors had left a similar chair by the dumpster.

Sure enough, it had the lift cylinder that I needed, so I grabbed it, took it apart, switched bases and I was back in business.

I don't know where you might find a chair that you could cannibalize, but perhaps a thrift store, Goodwill, or maybe a large company with lots of office chairs that has some to dispose of?

Do you live in an area where there are places you could call to check whether they have some throw aways? If you do, as they use to say, "let your fingers do the walking" on Monday. smiling smiley

I know how you feel. Not a lot of money to just go out and buy another chair and feeling frustrated because your chair is fine except for this "little" kink. sad smiley

Or just buy a new cheap chair and swap cylinders.
