I read the reviews and checked that my chair was compatible with this Cylinder replacement. Google told me that my chair had the most common cylinder with a 2" (50mm) base. I ordered this Huiguli cylinder to replace my old one. Taking the old cylinder off was a little tough, as mentioned in many other reviews. I tried to hammer the swivel base with casters off the chair, but had no room to work and no luck. So, I unscrewed the baseplate from the chair. I turned the base upside down in my workbench and proceeded to knock out the old cylinder with a hammer. I destroyed it, because I had to hit it so hard and directly in the center to dislodge it from the base. But that did the trick. I then used vice grips to grab hold of the old cylinder and turned & "unscrewed" it from the base. The new cylinder was simple to put on. After screwing the baseplate back onto the chair, I then replaced the old plastic cylinder protector onto the new cylinder, then slid the cylinder into the baseplate. I then replaced the old base with the casters. The new base is fantastic. I have no evidence of durability because it is brand new. But, it works great and goes "extremely" high if needed. It is a little higher than the old base at it's bottom position, but that is fine, as the old one was very short at it's bottom position. I am extremely happy with my purchase, that came within 6 hrs of ordering. It sure beats having to buy a new $400+ big and tall chair. Review: Great replacement cylinder - I was ready to haul my chair to the dump when I noticed that replacement cylinders were available. My chair was not high enough for my workbench so I ordered a cylinder that was a few inches longer. It fit perfectly and now my chair is the right height. Works great. ## Features - Extra-Wide Adjustable Height Range: Enjoy a generous 5.9-inch (150mm) lift range, from a minimum of 11.8" to a maximum of 17.7". To ensure a perfect fit, please measure your old cylinder before ordering, as the installed height may differ and result in a higher seating position than expected. - Drop-In Compatibility: With a 2" (50mm) outer diameter, 1.1" (28mm) piston diameter, and 1.77" (45mm) base shaft, this gas lift cylinder is built to match most standard office chairs that accept a 2-inch mounting hole. Check dimensions to ensure compatibility. - Reliability & Safety: Upgrade your office chair with this Class-4 hydraulic gas lift cylinder, which has passed international SGS & BIFMA certifications. Supporting up to 1000 lbs without wobble, leakage, or failure, it is engineered from thickened steel with an anti-explosion decompression design, making it the ultimate office chair cylinder replacement for long-term peace of mind. - 360° Swivel & Ultra-Smooth Lift: Thanks to precision sealing and gas-powered shock absorption, you’ll experience silky-smooth height adjustments and quiet 360° rotation. No creaks, no jerks—just seamless movement and a more peaceful workspace. - Ease of Installation: Simply remove the protective cap (if present), remove the old pneumatic lift (rubber mallet recommended), insert this new office chair piston, and you’re done—no extra screws or complex steps required. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Huiguli | | Color | Black | | Compressed Length | 30 centimeters | | Extended Length | 17.7 inches | | Material | Stainless Steel | | Material Type | Stainless Steel | | Number of Packs | 1 | | Operating Force | 1000 pound_force | | Operating force | 1000 pound_force | ## Product Details - **Brand:** Huiguli - **Color:** Black - **Extended Length:** 17.7 Inches - **Material:** Stainless Steel - **Operating force:** 1000 Pound Force ## Images ![Office Chair Cylinder Replacement 5.9" Stroke Heavy Duty Class 4 | Hydraulic Pneumatic Gas Lift Cylinder, 1000 lbs Capacity, 12-18" Extended, Universal Fit for Most Executive Office Chairs - Image 1](https://m.media-amazon.com/images/I/61mTffAKHcL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Must Read, GREAT product! *by T***K on February 1, 2026* So my Real Space DRG gaming chair was sinking.

My chair was not high enough for my workbench so I ordered a cylinder that was a few inches longer. It fit perfectly and now my chair is the right height. Works great. ### ⭐⭐⭐⭐⭐ If you need extra height, this is the cylinder to buy. *by I***R on June 29, 2026* If you need extra height, this is the cylinder to buy. I purchased this office chair replacement cylinder because I needed one that's taller than average. Our original cylinder kept sinking, and since we're using the chair at an assembly workstation, the extra height was important. This heavy-duty Class 4 gas lift (12" to 18" adjustable with a 1,000 lb capacity) has been perfect for the job. It raises the chair higher than a standard cylinder and has no trouble supporting heavier loads. On a funny note, it has so much lifting force that my wife, who weighs under 120 pounds, can't get it to compress. It actually gives me a chuckle every time she tries. If you're looking for a heavy-duty, extra-tall replacement cylinder, this one has worked great for us. ## Frequently Bought Together - Huiguli Office Chair Cylinder Replacement, Heavy-Duty Class 4 Hydraulic Pneumatic Gas Lift Cylinder (Supports 1000 lbs), Universal Size Chair Piston, Fits Most Chairs, Office Chair Parts - 9 Inches to 13 Inches Office Chair Cylinder Replacement, 4" Stroke, Heavy Duty 1000lbs, Hydraulic Pneumatic Shock Piston, Universal Gas Cylinder Fit for Most Office Chairs, Class 4, Black - MySit Gas Lift Cylinder Removal Tools 28mm/1.1-Inch, Removal Tools Sets for Replace Office Chair Cylinder, Fix Sinking Office Chair Stainless Steel Chair Saver for Stop Sinking - 2 Pieces --- ## 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.ro/products/686903737-office-chair-cylinder-replacement-5-9-stroke-heavy-duty-class](https://www.desertcart.ro/products/686903737-office-chair-cylinder-replacement-5-9-stroke-heavy-duty-class) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-08-13*
