DOZYANT 6" Long Stroke Office Chair Gas Lift Cylinder Replacement,Hydraulic Pneumatic Shock Piston Heavy Duty (450 lbs) for Tall Person Universal Size Fits Most Executive Chairs, Highest End Class 4

I have some very expensive office chairs, and the cylinder went bad on them. I did not want to spend several hundred dollars for a new chair and was researching replacement of the cylinder online, when I came across this excellent value and easy to replace cylinder for my chairs. Now my chairs function just like as if they were new and give all the proper support. These heavy duty cylinders work excellent because I’m a pretty big guy weighing about 300 pounds and they support my weight all day.

My

Worked as expected. Replacement of the old one was easy and this fit as advertised.

Short and sweet: So far, so good, but be sure to remove the purple cap at the top of the cylinder before installing. If you don't you will have a hard time getting the lift mechanism of your chair to operate the cylinder. I installed the cylinder after a day of trying to remove the old one (WD-40, pipe wrenches, grip cloves, and a rubber mallet are your friends). After installing the new one I quickly realized the lift didn't work: The lever that controls the cylinder was coming to a hard stop. There are no instructions included in the package, so I had no clue there is a protective purple cap the prevents the button that releases the gas from being pressed while in transit. I didn't realize it until I removed the whole lift assembly from my chair and took a flathead screwdriver and mallet to it to see if I could press the button manually. The purple cap fell out while attempting to press the button with the screwdriver. Now that everything is in it's proper place, the lift works fine. Supports my 255 lbs easily and is VERY tall. I added some 4" nylon wheels to assist rolling on thick pile carpet, so my chair now sits almost as high as a barstool. I love it!

It works great, now I'm not slowly sinking down every time I use my desk.

Cumple su función y a muy buen precio

Easy installation. 50mm diameter. Worked well to replace my dxracer prince series gaming chair. This one is good for taller people.

The item is exactly as offered, and working very smoothly. It was delivered ahead of schedule. Thanks Amazon for a job very well done. Keep up the good work...

رائع جربته مع كرسي هارمن ميلر ايرون ثابت وجيد

Recently picked up a Desky chair and have found it pretty disappointing mainly due to the very low sitting height. After doing some research I found that chair lift cylinders are pretty much standardised so figured I’d give this one a go. After some struggle removing the old one (look up a guide, you’ll need a mallet and a pipe wrench) I was able to replace it and was immediately impressed with the added height. I’m 6’5 and at full extension my feet mostly dangle which is a new experience for me. I’ve been using it at the minimum height and it’s perfect for me. Very pleased with the result and has saved a very expensive chair!
