Turn chair upside down. Detach the seat from the stand. The gas cylinder will usually be stuck in the wheel base. Get a large pair of channel locks or locking pliers and someone with some muscle to force the old cylinder out. You may have to use oil or a few whacks with a mallet to loosen it. Then simply insert new cylinder into base and replace seat. Hope this helps.

Check Youtube, there's a couple videos on there I used. Basically hammer off the wheel base, (Wrap in towel to prevent damage if worried) by tapping each wheel leg until it pops off. Then Pipe wrench or vice grip the cylinder loose, or remove cylinder base then hammer out cylinder from the top.

the way I did mine was by using a hammer. turn the whole chair upside down an tap the center of the cylinder until it falls out of the chair base while kinda holding the base up .the harder part is tapping the mounting where the top of the cylinder shaft installs to the chair seat bottom. hold the cylinder an rest of the chair off the floor an tap harder next to the shaft mount until it falls off.tap on the steel part not the seat bottom. have fun.

There are plenty of videos on Youtube to show you how to replace the gas cylinder. It's not difficult, the hardest part is getting the base to release from the old cylinder. Reassembly is almost foolproof. It only goes together one way.

It is a compression mount to the seat bottom (top of cylinder) just like it is a compression mount for the wheels (bottom of cylinder. Remove the bracket from the bottom of the seat (4 bolts). To remove the old cylinder, I put mine in a vise and used a hammer and large punch to knock it out of the seat bracket. If you don't have a vise, use something that you can put the cylinder in between and rest the bracket on either side. It took diligence, but I finally got the old cylinder out. The new cylinder went in very easily. It will "set" the first time you sit in the chair.

Hi Melody, you can remove the glass cylinder, and if you need to you can order replacement cylinders.

I seem to recall a kit on Amazon for just that purpose. Do a search for it. Probably will come up if you first bring up the chair and scroll down the same page.

Hi Nikhil, if you look in the back of the lid, there is a button. press on that button and pull forward. this should slide out the seat cover and you replace it. Hope this was helpful.

Contact HON directly. They'll ship you a replacement. Google should get you contact information for their CS department. They may ask for proof of your purchase date which you can do by printing an Amazon invoice (assuming you bought the chair from Amazon).

Hi Jan, The stem and the wheel are all one unit permanently attached. It is usually the plastic part of the wheel that breaks but you need to pull the whole unit straight out of the bottom of the chair to put in the new unit. The old unit is in there tight and usually needs a strong pull to get it out. Depending on how your chair is set up it may help to use a strong flathead screwdriver to slip between the old wheel unit and the chair base to pry it out from the side. You can see the new unit has a little collar on the stem that catches inside the hole in the base. You just need to pry it enough to break that collar free from its place inside the hole. Once that is done it should come out fairly easy. I hope that helps. Good luck.

I guess that is the lift. Here is a link for a picture of how to measure.Rolland Office Chair Gas Lift Cylinder - Universal Size Fit All - Heavy Duty - Black

Most office chairs that have a lift mechanism use a standard socket for the base, and fit the socket under the seat where the adjusting lever does its job. Here's the thing -- if you order it from Amazon and it turns out not to fit, you can return it pretty easily for a credit. I've used these on "place" chairs, and manager's chairs. When it is time to remove the failed lift cylinder I recommend getting some BIG channel-lock pliers to twist the old one out of upper and lower sockets. Lay the chair on its side, grab the cylinder and turn both the cylinder and the leg-wheel base in opposite directions, then twist it out of the bottom of the seat. The new one just pops in-- no sweat.

The cylinder is held in the under chair mount and the bottom base by friction only. Remove the cylinder mount from the underside of the chair by removing the screws. Hit the top of the cylinder(extending through the chair mount) with a hammer while holding the mount. This should dislodge it from the mount. Now hit the bottom of the mount that extends through the chair base while holding the base. This should dislodge the cylinder from the base. You can place a piece of wood on the cylinder ends and hit the wood with the hammer if you are concerned about hitting the cylinder directly.

I've heard good things about SquareTrade but are they going to require you to ship the broken chair at your expense? That's the key question. If they don't require that, it's clearly worth it, for any chair. Even if it turns out to be worthless, it would be worth $20 to me just to get experience with SquareTrade to find out why people recommend them. And I've never had any office chair whose gas cylinder didn't loosen up and make the chair wobbly within a year or two. Would that be covered? It would be interesting to find out.

Hello Tony H! It would be best to use the Contact Seller option under your oder history and explain the issue. Replacement parts can be ordered for some furniture items, but not all. They can examine all options for you. I hope this helps. Thank you for choosing OfficeMax!

First, you get out of the chair! Then face the front of the chair, put you arms (both) down, on the inside of the arm rests, grab the edges of the seat and pry the edges of the seat together. I will require a little pressure but you can do it.

It sounds like you're talking about the bottom of the gas cylinder itself, which has a little clip keeping the parts from sliding free. The answer is "probably", if the chair originally came in multiple pieces (most likely) then you should be able to use a mallet to pound the base off the gas cylinder, and then use a pipe wrench to twist the cylinder free from the chair itself. You can find quite a few youtube videos showing this process, some recommend taking the base off first, others recommend removing the chair end first. I went with the former, and while it took some muscle, it definitely worked.Good luck!
