Style: Cylinder Replacement Kit
I've lived with a bad lift cylinder on my office chair at home for a few years now. Initial look online didn't lead me to believe the hydraulic cylinder would be easy to find or fix. And, it was easy enough to just live with it. Last week, I got fed up with sitting close to the floor while working at my desk;) So, I first browsed YouTube and found a couple of interesting videos about "repairing" the cylinder - at least I learned more about how they work. The button on my cylinder was permanently depressed, and I didn't want to try to rebuild it. Then, I searched Amazon, and this time there were many options available. Knowing that getting the old cylinder off would not be a trivial job, I was intrigued by this product that offered a removal tool and watched their videos. My old cylinder was about 2 inches in diameter and 11-inches long, unextended. So, the 2-inch by 15-inch description of this product led me to believe it would fit. It arrived today, and it took me about an hour to do the replacement (from receiving the package to final cleanup). The first challenge I ran into was the hard plastic cylinder shroud that came with the chair (to hide the cylinder and make it 'look nice'). That shroud prevented me from getting the enclosed Allen-wrench on the screws that cause the shaft to separate from the chair. So, I had to use a pair of channel-locks to grab the heads and rotate the screws about 1/16 of an inch at a time - a pain and time-consuming, but the knurled heads facilitated the process a lot! Great design thought. This step took the most time. After separating the bottom/cylinder/wheels from the chair, I placed the bottom section on two sawhorses and began to hammer away at the cylinder (I had no intention of trying to salvage it; just needed to get it out). After several blows with a regular claw hammer, I sprayed it with PB Blaster Penetrating Oil and waited 5 minutes. A few more taps with the regular hammer convinced me I needed more force. So, I pulled out a small 5-lb mallet. Four swings later, the cylinder popped out! Reassembly was a cinch. (I threw away the hard plastic shroud; this cylinder looks nice enough as is.) Tested the operation and was elated to have a like-new office chair once again. Kudos to The Office Oasis Store for this very functional and affordable product.

Style: Cylinder Replacement Kit
My 2002 Aeron cylinder blew (not bad since I sit in it every day and weigh 220, working from home for the past 2 years) so I was looking for a good replacement that didn't require ordering one through the local HM dealer. After evaluating many options I selected the Oasis kit - I looked at some two stage cylinders closer to the OEM but due to either shipment times or functional need (I don't need to go lower) this seemed like a good and affordable option. And the removal kit bits seemed like a good option after watching the numerous videos and reading plenty of forum posts about the difficulty removing old cylinders. Mine has been installed for 20 years, the past two with relatively hard use so I anticipated a challenge and it did not disappoint in terms of difficulty. I'll comment on the cylinder itself, and removal of the old cylinder as separate (but related) issues. The cylinder itself has worked great - as others have noted it does not sit in the base of the Aeron as deeply as the OEM cylinder, thus it does raise the maximum chair height by an inch or two. If this matters depends on the user - for me I wished for maybe another inch with the OEM fully extended - worked fine but the perfect height for my "desk" (a repurposed drop leaf table) would have been a bit higher. So this replacement works well - I have it lowered just a hair as the highest setting is a bit high for my situation but the flexibility is nice. Do note the instructions online for adjusting the lever screw that presses against the cylinder button - I did have to tweak mine a bit as the prior setting for the OEM cylinder was too long and resulted in the replacement not holding the height when seated but it's a quick and easy adjustment - works perfectly now. The button on the OEM part is shorter than the replacement so this was expected - but for anyone wondering the taller button on the Oasis does work with the Aeron! Removal of the old cylinder... I don't have a 12 or 14" pipe wrench and while I have a good assortment of tools wasn't that driven to get one for this project alone (since I've never needed one otherwise in 20 years of home maintenance). Prior to receiving this new cylinder I'd given removal of the old one a go using 10" slip joint pliers, vise grips, with no success. Soaked the joint with liquid wrench penetrating oil and was getting no result whatsoever. Not a budge. Again my old cylinder was well and truly lodged. So I was anxious to try the removal tool included with this kit and using it I was able to dislodge the seat from the post! So it does work - here are some tips for use: first my cylinder had spewed grease/oil when it blew so I found that just wiping the post with a dry paper towel/cloth did not get the post clean enough for the removal tool part that you clamp down to gain a solid grip. I used some simple green degreaser, then a run of rubbing alcohol to insure the post was really clean. Once I did that I was able to clamp down the collar (and do clamp it down tight!) and it held. At that point it was just a matter of slowly turning the "pressure" screws through the collar - 1/4 to 1/2 turn on one, then the other. I did find steady pressure on both sides worked well. If you go in smaller turns alternating each side you'll not need to apply a ton of torque to the allen wrench to achieve a result. I heard a fairly distinct pop when it first started to loosen and then it went pretty quickly - a few more turns and the seat detached from the post. So the removal tool does work with some patience and materials preparation. I've saved it for future use if needed. I do think it was easier than trying to torque it off with a wrench unless you already own a pretty long and heavy duty pipe wrench. Even then the screw pressure requires less oomph overall than even a pipe wrench I would think. Note that the removal tool gets the seat off but does not remove the old cylinder from the wheel base. Given the ability to use a mallet or dead weight hammer on the base (unlike the seat) it probably isn't needed but do expect to spend some effort getting the base removed as well. I used penetrating oil and a rubber mallet with little success. Here are my tips on that part of the job if yours is stuck. First expect to take some whacks at it - like maybe not 2 or 3 ;) I used the edge of my lower deck (around 2 feet off the ground) with some padding to make sure when it released it hit the ground and didn't take off a toe. You'll need a stable surface for sure. I decided to leave mine outside for an hour or two in 40s temps to shrink the metal and that seemed to help. I also alternated hitting the bottom of the cylinder with sitting the cylinder bottom on the deck and alternating hitting the base with a rubber mallet on opposing legs (which gets the benefit of the longer leg leverage, as well as some offset pressure to eventually break the seating). It did eventually release but it does take some time. Have patience! New cylinder install is super easy - I did put some "no seize" lubricant on each end of the cylinder to give some minor aid if I ever need to replace this again - whether it will help I don't know but can't hurt anything.

Style: Cylinder Replacement Kit
Used this kit to replace a 400# lift piston that was only about 2 years old and not holding its position. As advertised, this kit includes a seat removal kit consisting of two lock rings (with Allen wrench and expansion screws) that are placed on the lift cylinder to slowly pry off the seat from the piston, and a very nice pair of stretchy work gloves to keep oil and grease from the old piston off of your hands as you work. The only problem I had (due to not fully reading the instruction sheet) was aligning the collars in the same position. They should be placed a little askew to prevent the separation screw from leaving one collar and entering the other -- the separation screw should go THROUGH the first collar and push on the second to leverage the seat off. The entire process was not as flawless as the video demo, but it is accurately portrayed. Overall, this kit (and video) made the removal/replacement very easy to do. And the extension of this piston is more than my old one. -- fully extended, I need to tip-toe to touch the floor. I love the extra height even if I don't plan to really use it. The final plus is that the piston has a lifetime warranty, but you have to register it. I think the kit is a great value and highly recommend it. especially if you want to rescue a heavy-duty office chair that you enjoy using.
