Customer Reviews
Both my son and my chair are about 3 years old now and will sink. Saw a few videos online about replacing it yourself and was discouraged by the amount of work and tools they took to do the job. Then I found one video that wasn't as popular that noted that all standard chairs are identical with respect to the installation of the lift cylinder. It's only a tight fit and they are all the same width.Following those very basic instructions I flipped the chair upside down and twisted the top of the old cylinder with a pipe wrench and it came right out. Did the same at the base and was done with removal in under a minute. puting the new one in was even easier -- just slide it into the vacated bottom and top holes and flip it back over then sit down hard. done.Now I have two perfectly working chairs. Holds its height and goes up and down smoothly. Very quick and easy installation -- if you don't own a large pipe wrench borrow one from a neighbor.The height is the only thing you have to match. I got this one because it was about an inch longer than the originals and my son and I are tall.
