This is exactly what I was looking for! I wanted a high seat to go with my uplift desk and this worked perfect with my chair, which was also purchased on Amazon.

If you are reading this review you are about to attempt to change the gas cylinder in your office chair.These are the tools: a medium hammer, a hex driver for removing the seat bottom, and a place to work where you can make noise.Steps are simple: 1. Put the chair on its side and whack the plastic base off while holding on to the top. It make take a few blows; you can also strike the bottom of the lift cylinder to get it moving; 2. Remove the seat bottom of the chair by loosening the screws on the bottom -these are usually hex drive screws; 3. The tricky part I learned by accident is take the chair and hold it upside down by the old cylinder and strike the flat part of the metal frame; you may have hit more than once; this where it is handy to have heavier hammer; I did this over a low table outside; 4. The weight of the metal chair structure will help separate off the cylinder; 5. Put the chair bottom on the frame; 6. Insert the new cylinder and then put on the plastic spider base;6. Put the chair right side up. Note: I put a higher lift cylinder to get more positions. Cost of the cylinder was about $22.

Installation was easy. Removing the old one was terrible. I’m 6’ 4” and over 300 lbs. so the old one was practically welded in it was so snug. But once this was in, what a difference. I’m fairly evenly distributed so my legs aren’t extremely long but most chairs are way too low. With the new 3” wheels and this new piston, my chair is perfect. The piston is fully collapsed at the lowest height and it’s perfect for my legs and posture now. I’m having to raise my desk 3 inches to be able to slide under it because it is also too short. Overall, it’s nice to finally have a chair that fits right and won’t fail on me because this piston is the right size. Maybe even a bit too tall.

This thing went so high I couldn't get in the chair. If you want a really high chair, or are very tall - this will be the one for you. Easy enough to install. The hardest part was removing the old cylinder

Wow! I tried to cancel this order, but Amazon wouldn't let me. Glad they didn't. Lol. This goes up to 2.7ft! Yes I measured it lol! I don't need that much height though. Hopefully this is sturdy & will pass the test of time. This comes w/ a 12 month warranty fyi. Hope it lasts for years!

I am not much for writing reviews but found it annoying that this broke right outside the return period. Doesn’t hold its height for more than a second before sinking down to the lowest point. Waste of time and money.

This was a good replacement cylinder to make my chair higher on an taller desk. It fit my chair perfectly and is smooth to go up and down. Installation was easy and this was my first time replacing a cylinder.No complaints so far, would recomend.Just a general note: If your replacing an older chair I would recommend to buy some lubricant and a pipe wrench. The old chair cylinder was very hard to get out. This new cylinder went in easy.𝗣𝗿𝗼𝘀:• Very tall• Good quality𝗖𝗼𝗻𝘀:• None

Lo compre porque el piston de mi silla era demasiado bajo y necesitaba uno mas alto y este cumple con todas mis expectivas. Facil de poner, muy alto y robustoAVISO: el de 55cm es MUY alto. Yo mido 1,87 y al minimo llego de puntillas al suelo (no me importa porque lo que buscaba era que el reposabrazos quedase a la altura de la mesa y eso lo cumple perfecto) pero si es verdad que con el modelo de 45 cm hubiese tenido mas que suficiente
