Husband had a heck of a time removing the old one, but this replacement popped right into place and works perfectly.

We've used this hydraulic cylinder twice to replace the worn out cylinders on two office chairs. Superb product that fits perfectly. Works as intended and we've not had any issues or problems with these cylinders. This hydraulic cylinder works better than the original. Very easy to install. Will definitely buy again if we need another chair hydraulic cylinder.

Purchased this lift to bring new life to my home office chair. The rest of the chair (tilt and tension) still works fine and the upholstery still looks good and is supportive. It just would not stay at the height I wanted. It had a slow leak. I would set it and an hour later it would be all the way down. I watched a couple of videos on replacing the cylinder and it was pretty straight forward. The hardest part was removing it from the seat. Even with a pipe wrench (aka monkey wrench), it was tough to remove. It is a friction fit - ever so slightly tapered to get tight and stay tight. It’s made that way so the legs won’t if you pick up the chair. Then, removed the cylinder from the legs (just hit it twice with a mallet), and it was off. Assembly was quick and easy: small end into the bottom of the chair, big end down into the leg assembly, sit on it and done. Good to not have to keep raising the chair every hour!

Pros: It works, relatively simple to put on and it fits but not perfectly but not a real big issue Cons: my hyken chairs lowest setting is now a lot higher than before with this lift, approximately 3-5 inches taller than with the stock hyken lift, the bottom fits well, but the top portion that goes into the hyken chair is slightly smaller than the original There was no struggle putting it into the chair, the only gripes i can say is the lowest setting is a lot higher than the stock lift

This office chair replacement pneumatic shock/lift cylinder (#S6111) from Amazon fits the "Thomasville Edinger Bonded Leather Big & Tall High-Back Chair" and likely others. There's some descriptions and instructions on the attached photo which can be zoomed in. You're saving yourself a lot of time and work by using the existing outer cylinder on your chair while just using the new inner cylinder. There's no need to remove the chair back or arms off of your Thomasville chair and just turn it face down supported by the back top and arms against the floor. Then remove the clip and washer off of the cylinder on the bottom of the star-base with a small screwdriver. Remove the star-wheeled base and it should come right off. The 1" diameter shock top will be stuck in the hole in the chair seat base. Take a pipe wrench and spray some WD-40 where the shock is in. Turn with a pipe wrench until it spins some then I used a pair of vice-grips to snap on the shock and smack it with a sideways hammer head to remove where it should come out. Take the new chair shock and remove the clip with washer on the bottom of the shaft where you then remove the outer cylinder. You won't even need this if your outer cylinder is in good shape. Make sure the washers, bearing, and any other small parts are transferred from the new cylinder/shock shaft to the old outer cylinder. The old washers, bearing and clip can be discarded. Then you can stick the upper 1" diameter cylinder attached to the base in the chair seat hole. Flip the chair right-side up and sit on it a few times to anchor the cylinder in the bottom of the seat bracket. No need to make any adjustment to the plastic button on top for the Thomasville chair and seat height can be adjusted even if the new shock is a little higher. Good luck and hope this helps.

This is day one review... I will edit and update as necessary. The product includes no instructions... see YouTube. For my 2005 Steelcase Leap chair, I could not get to the end of shaft that was in the chair seat assembly with the pipe wrench. I had to twist the outer section about 15 times with a bit of pressure away from the seat. It gave me enough space to just get the jaws of the pipe wrench around the seat shaft. I did this with the chair on its side on the floor. Once I got the wrench on the proper shaft, it took a bit of effort to get it to turn. Use WD 40 and whack it a few times to start up some vibration. Once it breaks free it will come right out. I then placed the caster base ("legs") over a large trash can with the shaft pointed down. I used a hard mallet (you can use a hammer, but don't miss and hit a chair leg as they will break) and had to strike the shaft protruding from the bottom of the castor base with a sharp blow to free it. Once free, I inserted this new cylinder into the castor base and then into the seat base. Immediately the chair rose... I had to remove the seat using the slide release and a screwdriver to release the catch (keeps the seat from coming off during normal use). This procedure is also on YouTube. There is a allen head screw over the cylinder and I had to back it out about 2 full turns counterclockwise). I kept checking as you only want to back it out just enough as to not engage the cylinder button release unless the chair lever is being used to adjust height. Hope this helps...
