My chair used to go down and stuck there, it takes extremely high strength to pull it back to original position, I was really fed up and thought of buying a new chair, but with some youtube videos i was able to find the problem is with the Gas lift cylinder and was able to find this product in amazon, highly recommend this product, though my review is after short term usage only but the product seems strong and i hope i can easily use it for 2 yrs or so. Just spent an hour and taking youtube videos help, i was able to fit it myself

Its is a great gas lift for generic office chairs.Please check if your chair has a generic gas lift before purchasing.Installation of this gas lift requires some mechanical skills.1. Remove the red cap plastic cover on top of the piston, just hold it with a plier and pull it off.2. Remove the chair upholstery from the bottom half of the chair, so that the chair seat is taken out of its resting plate.3. Keep some cushion / similar material to avoid floor damage and turn the bottom half upside down so that the wheelbase is at the top and the metal plate is slightly above the ground.4. Hammer the old central gas lift rod present in the chair, that sticks out from the wheel base; while hammering, you will notice that it's sinking until it eventually comes off.5. Keeping the same upside down position, hold the gas lift and hammer the plate evenly from all the sides , forcing the plate to fall on the ground. Hit the plate as close to the gas lift rod, with the plate facing downward slightly above the ground. After a lot of hammering, eventually this would give way as well.6. Remove and replace the plastic hosing (if present).7. Place the new gas lift with its red button facing upward onto the wheel base of the chair. Place the plastic hosing back on the wheel base through the gas lift.8. Now place the plate back on the gas lift so that its flat portion faces upward and it sits above the red button of the gas lift.9. Simply sit on the plate and release the lock to check if everything works. Move up and down a couple of times and your weight is enough to hold them back together.10. Place the seat back on the plate and that's it! Enjoy your chair.The product is as good as how my old gas lift used to be working, go for it as its less expensive but of good quality.

I saw a video showing how to replace the chair lift mechanism. It seemed simple. When i saw the replacement on Amazon, I thought I'll be saving some money. Since it was an old chair and 15 years since I got replacement of the mechanism, I found it hard to remove the old one. Finally I removed it and ordered the replacement. Unfortunately, it was too big for the Godrej chair. All the products are showing same size of 120 mm. So I have to contact the local dealer for replacing the mechanism.

Its full length is only 5 inches more than the contracted length. I dont blame the seller coz it clearly mentions 15 inches. But if you are looking for something with a higher lift, then go for a product which has more than 15 inches length when fully extended.Otherwise, the product is good quality. Have been using for a month, no issues at all.

When my chair started sinking on its own, the first thing I did was call up the local furniture store who sought 1.5k to fix it. I looked up online to know what the cause could be and found that I just had to replace the hydraulic cylinder and I could do it myself with a spanner & a hammer. I did. It worked. The product is as described by the seller. Seems sturdy enough. Will update the review after a few months of usage.
