The Original Office Chair Cylinder Removal Tool (As Seen On PBS) - Easily Remove Your Old Gas Lift Piston from Any Office Chair

Works perfect for getting the top part of the lift out of my Herman Miller Aeron! I tried a pipe wrench no luck this easily popped it out and a couple blows from a hammer loosened the base of the lift, install was so easy.

As others say, it's the right tool for the job! One thing to check before buying is the diameter of your chair's cylinder: The cylinder grabber tool has an inside diameter of about 1.00 inch. If your cylinder diameter is too much different from that, near the seat bottom, the tool will have a hard time grabbing the cylinder. It worked perfectly with my Staples office chair.To quantify the problem of not enough room under the chair: the thickness of the two doughnuts plus the exposed length of the extraction screw plus the Allen wrench amounts to about 3.3 inches. You need to have that much clear distance to work, or else the tools are going to be bumping into things.

I will probably never use this again, I can see myself lending it to friends and family, to fix their chairs. I can tell you that having the right tool for the job was more than worth the price, what this would have cost to have a professional fix it was astronomical. My total cost all in is right around $50. This thing worked like a charm.😊

Works great, as stated. You can remove the piston with ease using this. However, you can also do it without this tool by placing you foot firmly on chair base, grabbing the armrests, and shaking the chair side to side while pulling upward. Requires quite a bit of effort, but it can be done. This tool makes it easy with no physical exertion. You will still net a hammer or mallet to bang the bottom of the piston out of the base. You can find several YouTube videos on this.

Worked where a pipe wrench had failed. Sprayed cylinder with wd40 and left overnight then used this and the cylinder popped right out.

Worked perfectly to remove the cylinder from an Embody chair. I cleaned both the cylinder surface and the inside contact surfaces of the provided collars prior to application, and had no issues with grip. Less than one turn on each drive screw once they had been finger threaded to contact and the cylinder was free with no risk of damage to the chair.

I was ready to throw away a Steelcase Leap V1 I picked up from surplus at work due to a worn-out cylinder that refused to budge. The suggested method from the replacement cylinder manufacturer (a pipe wrench) simply didn’t work no matter how hard I tried.I found this tool on Amazon and decided to give it a shot since I had already spent sixty dollars on the replacement cylinder and didn’t want it all to go to waste.The tool worked perfectly. In literally a matter of minutes I had the old cylinder removed from the seat with almost no effort. Hugely thankful this item exists!

Why did they design these so that they're the same thickness as the bottom of gas cylinders? That's zero insight. They should be thicker so that the bolts don't interfere with the gas cylinder. As such, this tool does NOT work well for low-profile gas cylinders. And yes, I have the cylinder in the highest position prior to using this product. Worse, the intended longer bolts will not fit since there is not enough room between the cylinder base and the bottom ring you mount. So I had to use the longer bolts in one of the rings, and then steal the shorter bolts to use for pushing the two rings apart. This means I had to push the rings apart a little, re-seat the lower ring, and repeat about 3-4 times. And the shorter bolts are not tampered as much at their ends like the longer bolts, so applying pressure will deform the last bit of thread, making them more difficult to remove later. I even had to cut off my chair's plastic dust covers just to use the shorter bolts, which means throwing them away afterwards.Finally, using this tool is destructive, as the bolts will scrape away metal from the rings when used (see photos).This "original" office chair cylinder removal tool isn't so great. So many oversights make this tool a poor purchase.
