I need a new chair, this Markus is getting on a bit and is becoming pretty damn uncomfortable now. I spend way to much time sat at this desk and feel I should probably buy something semi decent. I have been looking at new Mirra's which come to around £630ish fully loaded. Second hand on ebay for around £250-300, same for the Leap v2. Also taken a look at some of the DX/AK race seat style chairs. Are these any good at all? Leaps seem difficult to find other than the bay. For those with one I assume that is where you got yours? I think I prefer the mesh style of the Mirra over the fabric of the leap. So many decisions and so difficult to try them out first.
