Holds position well. *by on Reviewed in the United States May 29, 2025* I got this to replace a faulty cylinder on a Staples mesh office chair. The old cylinder would weep down over the course of about 20 minutes, forcing me to raise myself back up many times per day. I considered getting a new office chair, but aside from the faulty cylinder, this chair is still in great condition and is very comfortable.At first I ordered one that was too tall. It wouldn't let me adjust the chair so that my feet would touch the floor. So I bought this one instead. This one is a bit taller than the original cylinder, but I never needed the chair to be really low so that's fine. This one does allow the chair to be adjusted much taller than the old cylinder. The old one needed to be all the way up for the chair to be at a comfortable height and with this one the best height is about halfway up which is great!Since I was going to be performing surgery on my chair, I also ordered a set of polyurethane double wheels for it and I love them too! I will never use plastic wheels on an office chair anymore. These poly wheels are super nice.Overall, I turned my mediocre but comfortable office chair into a super-nice, smooth, adjustable chair that holds its height. So far I am very happy. Will it last? Time will tell. I expect run-of-the-mill chair cylinders probably last about three or four years, but my Herman Miller Aeron cylinder is probably 20 years old and still works fine.If your office chair cylinder is failing and you like your chair otherwise, then get this one. You won't be disappointed!! ### ⭐⭐⭐⭐⭐ Heavy-Duty and Reliable — Just Measure First *by on Reviewed in the United States June 24, 2025* This replacement cylinder is a beast—strong, sturdy, and a great value for the price. It was easy to install and instantly made my chair feel more solid and secure. The product claims to hold up to 1000 pounds, and it really does feel that strong. No wobble, no slow sinking over time like my old one. My wife comes into my office and i'm not worried to have her hop onto my lap.That said, I made the mistake of not measuring beforehand. I was using this on a Lazyboy executive chair, and the new lift was taller than expected. Now my knees bump into the underside of the desk, which was on me for not double-checking specs. I’ve since ordered a shorter one, but I’m saving this for another chair because the quality is excellent.If you need a tall, heavy-duty gas lift and have the space for it, this is a solid choice. Just be sure to measure your setup first! ### ⭐⭐⭐⭐⭐ GREAT *by on Reviewed in the United States September 10, 2026* GREAT ## Frequently Bought Together - HOSALI 2.5 inch Office Chair Gas Lift Cylinder-Office Chair Replacement Parts, Heavy-Duty Gas Lift Cylinder Fits Most Chairs,Highest End Class 4 Hydraulic Pneumatic Piston,Universal Size - MASTERY MART 28" Heavy Duty Office Chair Base Replacement Parts, 2500 Lbs, Desk Chair Reinforced Metal Leg with Universal Gas Cylinder Hole and Casters Sockets, Matte Black - Besitu 500Lbs Office Chair Replacement Parts, w/ 6'' x 10.2" Mounting Holes Chair Base Heavy Duty Plate Swivel Tilt Control Seat Mechanism for Executive and Gaming Chairs --- ## 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/530483637-hosali-2-5-inch-office-chair-gas-lift-cylinder-office](https://www.desertcart.tn/products/530483637-hosali-2-5-inch-office-chair-gas-lift-cylinder-office) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-18*
