Was definitely worth spending a few bucks to get the removal tool. I used the interior piston only for my chair which makes the installation process even more easier. Review: Worked Perfectly, Needed Stubby Hex Keys - During the pandemic, safer at home days, I started to notice that my posture was a little off and my lower back was starting to hurt. I then noticed that the chair wasn't in the proper position any longer and I was not able to raise it any higher. I knew immediately that I needed a new chair or the back pain would progressively start getting worse. However, knowing that desertcart sells everything, I decided to see if they sold just the cylinder replacement since a new chair would cost me about $200 (and my current chair was in really good condition other than the cylinder height). I opted to purchase this item due to it being a full kit as well as offering a coupon discount. When the kit arrived, my initial install try failed miserably. First, I was not able to remove the chair as I couldn't slip the hex key between the bottom collar and the stock plastic sleeve that covers the "unsightly" cylinder. I know I could've cut the sleeves off, giving me the clearance. But, I wanted to maintain the original look of the chair as much as possible. Second, no matter how hard I hammered at the bottom of the cylinder with the rubber mallet, it refused to budge and I couldn't get it to detach from the base. I even soaked the seam with WD-40 and let it sit overnight. Still, no movement at all. Try number two. I turned back to desertcart to see if they sold stubby hex keys, which I immediately ordered. Day number two, the stubbies were delivered and voila, fit perfectly between the collars and the plastic sleeves. Next thing you know, the chair was detached. I then turned my attention back to the base... I took the base and placed it on top of a five-gallon bucket and again, soaked the seam with WD-40. After an hour, I hammered the cylinder again with the mallet and to no avail. I finally turned to a metal hammer and used the side of the hammer to equally disperse the energy to the edge of the cylinder base. After a couple of strong strikes, the cylinder popped right out. Excitedly, I cleaned off the WD-40 from the base, installed the new cylinder on the base, removed the plastic button cap, and installed the chair. The cylinder worked perfectly and at its highest height, I couldn't even place my feet flat on the ground (and I'm 6'1"). This cylinder replacement, even with the stubby hex key set purchase, saved me about $140. For those who prefer a tl;dr version/tips: 1.) Buy a stubby hex key kit if the included hex key will not work between the bottom collar and plastic cylinder sleeves 2.) Remove the chair using the included collars 3.) Place chair base and cylinder upside down into a five-gallon bucket 4.) Hammer the cylinder through using the flat side of the hammer (or use a block of wood between the cylinder and hammer) 4a.) A rubber mallet was not strong enough ## Features - EASY INSTALLATION WITH ALL REQUIRED TOOLS INCLUDED.

A rubber mallet was not strong enough ### ⭐⭐⭐⭐ Nice Cylinder, Good Support, DOES NOT Work with Steelcase Leap Chair v1 out of box *by J***N on July 29, 2021* I ordered this cylinder to replace the cylinder that came with my refurbished Steelcase Leap Chair v1 that I ordered in March 2020. TL;DR The cylinder needs modification in order to work with the Leap Chair v1. You may want to look at different cylinders if that is the chair you have. The cylinder fits in the chair perfectly and seems higher quality that what came with my refurbished chair. The installation kit was excellent, the hardest part was removing the old cylinder from the base. If you don't have a rubber mallet, go to Harbor Freight and get a cheap one. It makes removal much easier and quieter than using a board and hammer. With regards to the Steelcase Leap Chair v1 issue: the plastic button at the top of the cylinder that activates moving the chair up or down is too tall for the Leap v1, the button ends up always being activated. If you take a hacksaw to that plastic button and cut it off flush with the metal cylinder housing it will work. The portion I cut through was all plastic so I don't expect any issues. I did have to put the set screw under the seat almost all the way down after cutting the cylinder activation button. Prior to that I had almost removed the set screw to attempt to get the cylinder to work. When I initially got the cylinder I contacted support and they got back to me within 24 hours and once they had a good understanding of the issue they sent me a second cylinder to try. This cylinder had the same issue when it came to my chair because the issue is not a defect but rather an aspect of the design. I was offered a refund, but at this point I decided to try cutting the button down and seeing if it worked. It did, so I declined the refund. While I wish the process had been a bit faster and it had worked with my chair out of the box, I can't complain too much since my chair works at this point. ## Frequently Bought Together - Office Chair Gas Cylinder Replacement Kit, Heavy Duty Class 4 Hydraulic Piston for Desk and Gaming Chairs, Kit Includes Removal Tool, Gloves, Universal Fit Gas Cylinder - The Office Oasis Original Rollerblade Office Chair Wheels (As Seen On PBS) - Smooth & Quiet Casters - Safe for Hardwood Floors & Carpet - Easy Installation with Universal Fit - Set of 5 - Red - Office Chair Replacement Parts-28'' Heavy Duty Base Replacement(2200Lbs) - Desk Chair Reinforced Metal Leg,Universal Caster and Gas Cylinder Size --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/71028725-office-chair-gas-cylinder-replacement-kit-heavy-duty-class-4](https://www.desertcart.tn/products/71028725-office-chair-gas-cylinder-replacement-kit-heavy-duty-class-4) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-03*
