MYFULLY Gas Lift Cylinder Replacement | Heavy Duty 385lb/175kg Office Chair Gas Lift Cylinder 5 inch Long Stroke Adjust Universal Size Lift Cylinder Fits Most Executive Chair Swivel Chair : Amazon.ca: Home

My chair's cylinder wore out and I needed a replacement. I thought I'd take a chance on this one since it has an extended reach and claims it's "Heavy Duty 385lb." However, when I received the item it was very lightweight and marked with a Class 2 rating. My old cylinder was Class 3, so I did some research and learned that Class 2 uses thinner gauge steel and shouldn't be used for more than 220 lbs. There's no way this listing is accurate, but I used it anyways and after less than a week it started to leak oil. Don't bother with this cheap junk.
