## Questions & Answers

**Q: what does the 7" relate to?**
A: It relates to the length of the gas lift body (black bit). Hope that helps?

**Q: Will this fit my ikea markus office chair?**
A: Hi

They are standard fit for most chairs but the only way to be sure is to measure the top and bottom of the existing lift. If 25mm at top and 50mm at the bottom then all OK

**Q: Is the 8 inch cylinder available**
A: HiNo, but either the 7" or 9" will fit

**Q: Does this really lift 250kg? i bought one rated at 200kg from other amazon seller  (good ratings) and it couldn't support my weight of 112kg.**
A: Sorry I can't say as I only weigh 12 stone. But it as lasted a lot of years longer than the original one

## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great replacement for original unit
  

*by R***P on Reviewed in the United Kingdom on 16 July 2022*

I bought this to replace the original unit in my Ikea office chair that was tired and leaking oil.I followed the guidance given by another reviewer and removed the base and wheels from the chair.I found that holding the wheels in my hand and hitting the bottom of the old gas strut a couple of times with a club hammer released it.Getting the gas strut to release from the chair base plate itself was slightly harder, but again I followed the guidance, clamped the chair base plate in a vice and used stilsons on the gas strut.  It took a couple of firm taps on the stilsons with a hammer, but the gas strut then released.Once the old unit was removed, fitting the new unit was simple, and the chair has a new lease of life.Unit seems high quality, was a direct replacement for the old one I removed and seems to have the same range of travel, albeit the chair sits slightly higher at full "up", as the new unit isn't tired like the old one was.Excellent value.  Highly recommended.

    Good quality cylinder. Easy to install.
  

*by L***T on Reviewed in the United Kingdom on 19 March 2018*

Fits perfectly and works well every time. No leakage of gas so the chair doesn't sink like with my old cylinder.Hardest part of the installation was removing the old one. This one installed with almost no effort.

    Great gas lifter which has given my office chair a new lease of life
  

*by J***N on Reviewed in the United Kingdom on 15 June 2019*

This gas lifter replaced my old chair lifter, which never worked properly from new.This appears to be good quality and easy to fit.It goes up and down with ease and fit my office chair perfectly.The only minor issue is it does make a bit of a clunk as I sit in the chair, I think this is just because it is new. I will update this review if it changes in any way.But at present would I recommend or buy again, yes to both.Note: I watched a few youtube videos on how to release the old lifter, in the end, I removed the base and wheels from the chair (4 Allen bolts). I place the wheels star part upside down between 2 chairs for support and hit the base of the lifter with a lump hammer, this only took 2 hits and the post was free.To remove the post from the seat base I put the base in a bench vice then fitted a mole grip to the post, it only took 2 turns and the post came out.I hope these methods prove helpful to you.
