Description

Description: Frustrated to find that the office chair you sit on for years start sagging or can’t go up and down anymore? But not ready to buy a new one because the rest of the chair is in perfect shape? Why not get to fix it by changing the gas lift cylinder by yourself? How to make sure the gas lift cylinder fits your office chair? Check the outer and inner diameter of your broken gas lift cylinder. This replacement part fits the one with an outer diameter of 2" and inner diameter of 1.1". How to install the gas lift cylinder on your own? 1. Tip the chair onto its side. 2. Use the rubber mallet to tap and remove the base of the chair away from the seat. 3. Use the pipe wrench to clamp tightly onto the top of the cylinder. Twist and then pull up in order to remove the cylinder. 4. Remove the orange cap of the new cylinder. Insert the bottom of the cylinder into the center of the chair base. 5. Carefully lift both the chair base and the chair cylinder into the chair mechanism. The parts will then fasten on their own.

    • Good product as the height adds comfort. The value is not just in the price but also the product.
Take a look at this product, it is well worth the purchase. For a taller chair seat, this does the job. It was a better and more sturdy lift-tube than my old one. It put my feet, knees and hips in a more neutral position for better comfort. Less cramped = more Comfort. A word though: it is an easy install once the old one is removed. Removing the old lift-tube can be tough. ... show more

    • Updated review: May need to adjust your chair's adjustment lever tolerance
Updated review: I ordered a replacement from another brand. Upon installation, I noticed the exact same issue: When sitting down, the seat would slowly drop. It occurred to me that the button on the top of the cylinder that activates the height adjustment was ever so slightly depressed. The cylinder had gone into a Herman Miller Classic Aeron chair, which is cable driven and has a lever that activates the push button on the cylinder. The lever has an adjustment screw which needed to be backed out slightly. Once I adjusted the screw in combination with the new cylinder, it worked perfectly. Apologies for blaming this on the product. I'm sure if I had adjusted this screw properly, this cylinder would have worked just fine as well. Original review: Noticed today, 52 days after I purchased it, that the chair no longer stays at the set height when sitting down. I bought this for two reasons: the extra-long height, and the additional weight capacity. I'm 6'5" and 300lbs, so I need both to sit without hip and knee joint pain. I expected the 450lb capacity would be plenty, but here I am, sitting low once again, with knee and hip pain. Can't return since it's past the 30 day return window. I feel scammed. ... show more

    • It managed 2 brutal years of use
I work from home and also tend to hibernate in my office in my spare time. This thing got 12+ hours of use on average, nearly daily for the last 26 months. Overall, it was great, but there was a minor drawback when it started making some squeaking sounds for several months after about 6 months of use. Luckily that did stop with time, but now the unit automatically raises itself every time you stand up. Luckily, it still holds the height correctly, but it requires you to lower the seat every time you sit down. I used it at about 75% of it's max height for the entire life of the unit. I probably won't buy it again due to the potential squeaking sound, but generally speaking, this thing held up well to the daily use and abuse. ... show more

    • This thing is Huge. Way too big for me
Can't leave it a bad review but I will ay this thing is ENORMOUS. I'm 5'8" and my feet don't even come CLOSE to touching the ground, I took all the wheels off the chair and I'm still a couple inches away. Unless you're like 6'2" I cannot imagine you'll enjoy this.

    • Pretty easy!
Get a pipe wrench and a mallet and it’s nearly seamless! Made my chair tall enough for my standing desk :)

Great product, drastically improved the height of my chair for further comfort.
