Fits 2019 Costco Chair sold in store - Easy Install
Great product and easy to install. I ordered it due to the sales volume of over 1K sold in past month - so no extensive research. I bought this for a Costco Office chair purchased in 2019. It's about 5/8" longer base than the original and it raises about 1.5" higher than the original. It took about 10 min to put this in.I used a small pipe wrench to release from the base. I then placed the base over a bucket and used a short piece of 2x2 and larger hammer and knocked it out of the base. It all slipped back together as planned.

Measure and compare
Easy 10 minute job. Check out You tube for installation tips. I used pipe wrench, hammer. and a garbage can. Stick the base upside down in the can and give the lift a whack. Done. My old base was not the exact size as the new so measure first. As a result, I am sitting higher than my old lift. I am going to give it a few days to see if that will be acceptable. As a further review. I discovered that my original unit was a smaller size at the bottom portion and that this unit did not insert fully. I had to return to get the right one.

Solid product so far, feels sturdy, and added some height to my chair.
So far so good! I just got this installed on my office chair. I knew it was going to be a bit taller than my original, but that is okay, I am 6'7" and a chair being a little taller is quite alright with me.However, it ended up being about 5 inches taller once fully extended! When I lean back in my chair MY FEET ACTUALLY DANGLE IN THE AIR!!!! I have not had this happen in quite a long time!1000% would DEFINITELY buy again!

Works very well.
Bought the bigger cylinder so at its lowest point is the desired chair height and therefore acts as a solid mount. (Because I don’t need to raise the chair).

Superb!
EXACTLY what I was looking for. Fits perfect, made of strong material, and the 5.5” is an extra bonus. I’m 6’2” and my feet now dangle off my chair! Would definitely recommend to those who don’t want to replace the entire chair.

Directions would have been helpful.
I'm very handy and have many tools to help out. The piston was the right diameter but the bottom part (sleeve) was to big to fit. I had to swap out the old sleeve with the new to get it to work.You will need a stillson wrench to free the piston from the seat. And something to support the legs and a small sledge hammer to knock out the bottom part of the piston. (I used a partially open vice)Works very well so far.
