[Maakuth]

I have used a number of Markus-chairs and they are pretty good indeed, and not that expensive. The most surprising thing was when the cylinder in mine, after years of use, started to slowly drift (some internal gasket leaking or something) downwards after raising the seat. I contacted IKEA if I could get a new cylinder for it, but it turned out the 9 year old chair still had some warranty left. A delivery man brought me a brand new replacement chair and took away the old one.
