If you own a Herman Miller Aeron, you know how tricky it is to replace the gas cylinder on your own. The brand discourages its customers to do DIY on any of its units.

Where to buy

VDE no tools required office cylinder replacement – Best Budget

Our first option comes complete with tools for easier installation. But if you want to go tooless and have a more simple DIY, this product may suit your needs better. Though at first glance, it does not seem that it can do the job. It looks like a 3D plastic clamp aka toy. 

Well, yeah it is composed of 3 plastic clamps that measure 4 cm tall. You just need to open the clap and prop it on the hydraulic shaft and close it. And it does work. For something that can look close to a toy, it does seem to hold up pretty well. And since it has 3 clamps so you can stack ’em up, use 3 or just use one. So you can find a more comfortable height for the chair. 

One of our qualms, however, the three clamps are of the same size. It could have been more valuable if it is available in several sizes. 

As for the installation, you will be able to finish it in 5 minutes, 10 minutes tops. So it will not take a huge chunk of your time. It’s tooless, fast and easy. 

The downside is that it seems to hold up pretty well but not for tall and big chairs. We wouldn’t recommend it for tall and heavy users. Since it’s made of entirely plastic and doesn’t have a latch, there’s a danger of the snap hinge failing with a very heavy load. So we recommend this one for those who are skinny to average size users.

And the warranty is not also that clear, so this is more of a light-duty chair cylinder replacement tool.

HOTTHAT Heavy duty office chair cylinder replacement kit – Best for Big and Tall chairs

If number two is meant for light-duty chairs, this HOTTHAT replacement tool is what you need for tall and big office chairs. It is heavy duty and can bear a weight of over 500 lbs. It is also quite universal and can be used for most chair styles and brands.

What sets this product apart is not only its robust build. This also ensures that there will be no explosions. It’s also easier to change the chair height and it will not make any noise. The inside of the cylinder is made of stainless steel material, so you can expect it to perform better than the cheaper gas cylinders. 

One of the downsides, however, is meant for big and tall chairs. Even at the lowest setting, petite size users might still find the char too high. But in terms of stability and wear and tear, this can take on several abuses but still, there isn’t any creaking sound or any shaking at all. 

And since it does go higher than your old chair, this is also a good option if you want to bring your old office chair a bit higher. You’ll be able to add on a few more inches without having to buy a whole new office chair altogether. 

All in all, this gas cylinder replacement tool means serious business. It’s durable and has a higher weight capacity. It is a great fit for tall and big chairs.

Owl store gas cylinder replacement tool – Best Heavy Duty

If you find the number three option still lacking, this product from Owl Store can accommodate a whopping 1000 lbs. It is very heavy duty and can withstand such hefty weight. So even if you accidentally bounced your butt on the chair, this will be able to hold itself pretty well.

The removal tool is very easy to use. It has two rings to tighten the old cylinder. And you can easily push them apart. At the same time, the hex rings push the ring against the spring. And this motion easily props the column or the old cylinder out. You don’t need to use extra brute force just to remove the old cylinder. I also work for an old Aeron chair.

Though it will take you longer than 30 minutes to completely prop the old column out. The good news is, you don’t even have to sweat yourself out, you just need patience. The instructions are also pretty clear so you will not have to guess what to do next. So even if you are not mechanically inclined, you can still do it on your own. And it will not give you a headache. So pretty much everyone can follow the steps. 

It also looks kind of gorg compared to the other items on our list. The matte black finish lends a posh and sophisticated look. And oh, like option number three, this can also bring your old office chair a few inches higher.
